<div>----<br />
Wireless Cyber-Physical Simulator (WCPS) is an open-source simulation environment for wireless control systems.

== WCPS Architecture ==<br />
<br />
[[File:Wcps_framework.png|600px|thumb|right|Figure 1. WCPS Architecture]] <br />
<br />
As shown in the right figure, WCPS simulates<br />
the feedback control loop of the control system as follows.<br />
Sensor data is generated from structural models. Through a cross-platform function call from Simulink, sensor data is injected to the<br />
corresponding wireless sensors in TOSSIM. Following the routes<br />
and transmission schedule calculated by the network manager module,<br />
TOSSIM simulates the end-to-end wireless communication of<br />
the sensor data packets from the sensors to the base station, and<br />
then return the packet delay and loss to the Interfacing Block in<br />
Simulink through the Python interface. The Packet Collector module<br />
then extracts packet delivery information(the delay and loss)from the message pool. Sensor<br />
data and their loss and delay are then provided to the Data Block,<br />
which then feed the sensor data to the controller at the right time<br />
based on the packet delay (if the packet is not lost). WCPS utilizes<br />
basic API (e.g., the dos, UNIX command) of MATLAB to<br />
do cross-platform function calls. In TOSSIM, we re-implement a<br />
printf method in TinyOS to send simulation results to the<br />
Interfacing Block.<br />
<br />
User inputs to WCPS includes excitation signals to the structure<br />
(e.g., acceleration caused by earthquakes) and wireless traces used<br />
as input to TOSSIM. Excitation signal of the structure is provided<br />
to the structure models in the format of MAT files.<br />
The scheduler module calculates transmission schedules. Networking<br />
schedule is then deployed into the MAC layer code of<br />
wireless nodes and becomes effective after a TinyOS compilation.<br />
The TDMA MAC layer in WCPS is developed based on the MAC<br />
Layer Architecture (MLA) library and further adapted for<br />
TOSSIM under TinyOS 2.1.1. Received Signal Strength Indication(<br />
RSSI) and wireless noises traces are collected from real-world<br />
environments and provided to the wireless model used by TOSSIM<br />
for realistic wireless network simulations.<br />
The interfaces between the Simulink model<br />
and TOSSIM are encapsulated as two MATLAB embedded functions<br />
in Simulink: the Interfacing Block and the Data Block. The<br />
Interfacing Block extracts delay and loss information from TOSSIM<br />
messages, and the Data Block decides what data will be used for<br />
discrete control during each sampling period. The federated architecture<br />
of WCPS provides great flexibilities to incorporate different<br />
structural models and implement alternative scheduling-control<br />
approaches.<br />
<br />
== WCPS Capabilities ==<br />
<br />
This section briefly reviews application of WCPS in extensive Wireless Structural Control studies, which shows capability of WCPS enabling<br />
in-depth tradeoff among sensing synchronization, wireless network delays, as well as reliability of the wireless network. Specifically for the wireless network presented in this section,<br />
wireless traces in TOSSIM were collected from a 5-sensor testbed located at Bryan Hall of Washington University, as in Fig. 2. All results presented here uses the TDMA MAC layer.<br />
[[File:Building_network.png|200px|thumb|left|Figure. 2. Wireless Network in A Building]]<br />
<br />
[[File:Wcps building prr statistics.png|300px|thumb|right|Figure. 3. Network Statistics]]<br />
Fig. 3 shows end-to-end network ratio changes with different re-transmission mechanisms in WCPS.<br />
Sensor 1 has the lowest delivery ratio because it has a 2-hop route to the base station. Since OTDC-1<br />
does not perform any retransmission, while OTDC-2 and OTDC-3<br />
performs retransmit each packet once and twice, respectively. Under<br />
OTDC-1 Sensors 1 and 4 have delivery ratios of 70% and over 95%, respectively. As expected more retransmissions improve the<br />
deliver ratios of all sensors at the cost of longer delays as described earlier. <br />
<br />
[[File:Control perf building 1.png|300px|thumb|right|Figure 4. Tradeoff Among Data Synchronization, Network Reliability and Network Delay. ]]<br />
<br />
Fig. 4 shows changes of required resource for building control. Underlying tradeoffs are: better sensing synchronization vs. larger delays (e.g., OTDC-1 vs. SC), and <br />
larger network delays trading for better reliability (e.g., OTDC-3, OTDC-2 vs. OTDC-1). In Fig.4(a), OTDC-k approaches consistently require<br />
less control power than SC. As k increases, OTDC-k requires slightly less control power. Similarly, as shown in Fig. 2(b), OTDC-1 reduces control force by 80% when compared to SC. The<br />
differences in control force among different OTDC-k approaches are negligible. The results that OTDC-1 outperforms SC in both<br />
metrics indicate resource requirements are more sensitive to data synchronization than to sensing delays in this building control system.<br />
OTDC-k with larger k results in negligible reduction of control power and force, indicating resource requirements are not sensitive<br />
to network reliability in this case study.<br />
<br />
Fig. 5 shows control performance regarding structural response. In term of peak inter-story drift in Fig. 5(a), OTDC-<br />
k achieves more reduction in inter-story drift than SC. Interestingly, higher k in OTDC-k increases peak inter-story drift. Recall a higher k leads to higher communication reliability but longer<br />
sensing delay. Inter-story drift is thus more sensitive to sensing delays than to data loss in this case study. Similarly, as shown in Fig. 5(b), OTDC-3 causes worse peak acceleration than all the<br />
other approaches. Hence, building structural responses are more sensitive to sensing delays than to data loss. In addition, OTDC-1 only slightly outperforms SC, which indicates limited impact of<br />
data synchronization on structural response.<br />
<br />
[[File:Control perf building 2.png|300px|thumb|right|Figure 5. Tradeoff Among Data Synchronization, Network Reliability and Network Delay.]]<br />
WCPS has efficiently integrated TOSSIM and Simulink. Fig. 2-4 shows that there exist complex tradeoffs among data synchronization, sensing<br />
delay, and network reliability under realistic wireless structural control settings. A realistic, integrated wireless control simulator like WCPS is critical in exploring these design tradeoffs<br />
in wireless control design. Our cyber-physical simulation methodology and scheduling-control co-design approaches presented here not<br />
only represent a promising step toward smart civil infrastructure, but also provide useful insights and tools that can be generalized<br />
to other cyber-physical systems employing wireless control.<br />
<br />
==Environment Installation==<br />
* Install TinyOS<br />
<br />
<pre><br />
WCPS is implemented and tested on MacOS X (snowleopard), Windows XP, and Windows 7. Current release of WCPS is under TinyOS 2.1.1, which can be installed following the two methods.<br />
</pre><br />
* Follow the TinyOS official tutorial on installation of TinyOS for your specific platform: [http://docs.tinyos.net/tinywiki/index.php/Getting_started#User_Contributed_Methods Link]<br />
* Directly download the pre-tested TinyOS 2.1.1 image from here: [http://research.engineering.wustl.edu/~boli/downloads/tinyos-2.1.1.dmg TinyOS2.1.1 for SnowLeopard(and possibly later versions)] [Cygwin package coming soon.]<br />
<br />
* Install Mac Layer Architecture(MLA)<br />
<pre><br />
The MAC Layer Architecture (MLA) provides a component-based architecture for MAC protocols in wireless sensor networks. MLA extends the Unified Power <br />
Management Architecture to provide the hardware-independent interfaces required by timing sensitive MAC protocols, and defines platform-independent <br />
reusable components that implement MAC layer logic on top of them. The MLA architecture can be used to develop a large number of platform-independent <br />
MAC implementations, with little or no further effort required to adapt these implementations to new hardware platforms. Our current implementation of MLA<br />
is built on top of TinyOS 2.1.1. It currently supports platforms which use the CC2420 radio stack and has been tested on TelosB motes. In addition to providing<br />
interfaces and components for building new MAC layer implementations, MLA includes implementations of five representative MAC layers. Specifically for WCPS, we <br />
adopt and further change the pure-TDMA MAC protocol for centralized data communication. <br />
</pre><br />
<br />
* Follow the instructions here: [http://wsn.cse.wustl.edu/index.php?title=MAC_Layer_Architecture Install MLA].<br />
<br />
* Install MATLAB and Simulink<br />
* If you already have MATLAB MATLAB 7.11.0.584 (2010b) or later version, skip this step. Otherwise, follow the tutorial here: [http://www.mathworks.com/help/install/index.html install MATLAB]<br />
<br />
* Install Python<br />
If you already have Python 2.7.2 or later version installed, skip this step. Otherwise, follow the manual here: [http://www.python.org/getit/ install Python]<br />
<br />
== Download WCPS ==<br />
* [http://research.engineering.wustl.edu/~boli/downloads/cygwin.zip A complete package of Cygwin with TinyOS 2.1.1, MLA, TOSSIM pre-installed] with a [http://research.engineering.wustl.edu/~boli/downloads/WCPS_Cygwin_Installation_Usage_Tutorial.txt WCPS Cygwin Installation & Usage Tutorial]<br />

<br />
== Use WCPS ==<br />
<br />
Wireless network plays a critical role in close-loop wireless control system. Sitting on top of WCPS, simulating <br />
a wireless TDMA network is as easy as collecting these NesC files below:<br />
<br />
* "Makefile" takes advantage of the fact that it's not necessary to recompile all the files not changed while specifying all necessary libraries.<br />
* "TestNetwork.h" defines necessary message structures for the wireless communication.<br />
* "TestNetworkAppC.nc" connects claimed application interfaces to interfaces that are defined in the hardware library.<br />
* "TestNetworkC.nc" implements send/receive functionality of a wireless node.<br />
* "tossim-call.py" configures TOSSIM network and does packet injection into the Tossim network.[http://research.engineering.wustl.edu/~boli/downloads/TinyosFiles.zip All above necessary files.].<br />
* Re-implemented TOSSIM libraries for TDMA simulation.[http://research.engineering.wustl.edu/~boli/downloads/pure-tdma.zip TDMA components for TOSSIM.].<br />
* Wireless traces: [http://research.engineering.wustl.edu/~boli/downloads/building_noise_n_rssi.zip Traces for 5-sensor wireless network in a building].<br />
<br />
Put all the above files into the same folder, prompt a terminal (or a Cygwin window), and in the terminal run <br />
<pre><br />
Make micaz sim<br />
</pre><br />
<br />
If TinyOS and python is configured correctly, go ahead and run in the terminal:<br />
<pre><br />
./tossim-call.py<br />
</pre><br />
<br />
Having collected aforementioned TinyOS files, a simplified example that uses key networking Interfacing Block and Data Block of WCPS is shown in Fig. 6.<br />
[[File:Simple_wcps_example.png|500px|thumb|center|Figure 6. A Simple Example that uses Interfacing and Data Block of WCPS. ]]<br />
<br />
This examples shows:<br />
<br />
* How input data in Simulink is injected to TOSSIM network; <br />
* How TOSSIM Interfacing Block runs as a Matlab Embedded function; <br />
* What type of data is output from the Interfacing Block;<br />
* How data usage strategies are applied to the data in the Data Block.<br />
* What type of data is eventually output from the Data Block and provided for future control use.<br />
<br />
Source code for the example can be found [http://research.engineering.wustl.edu/~boli/downloads/simple_example.zip here].<br />

== Introduction ==<br />
<br />
The objective of this research is to develop wireless distributed monitoring and control systems to enhance the resiliency of our civil infrastructure. We employ a cyber-physical co-design approach that integrates wireless sensor-actuator networks and structural monitoring and control algorithms. The unified cyber-physical system architecture and abstractions employ reusable middleware services to develop hierarchical structural monitoring and control systems. <br />
<br />
The intellectual merit of this multi-disciplinary research includes:<br />
* A unified middleware architecture and abstractions for hierarchical sensing and control; <br />
* A reusable middleware service library for hierarchical structural monitoring and control; <br />
* Customizable time synchronization and synchronized sensing routines; <br />
* A holistic energy management scheme that maps structural monitoring and control onto a distributed wireless sensor-actuator architecture; <br />
* Dynamic sensor and actuator activation strategies to optimize for the requirements of monitoring, computing, and control;<br />
* Deployment and empirical validation of structural health monitoring and control systems on representative lab structures and in-service multi-span bridges. <br />
<br />
While the system constitutes a case study, it will enable the development of general principles that would be applicable to a broad range of engineering cyber-physical systems. <br />
<br />
This research will result in a reduction in the lifecycle costs and risks related to our civil infrastructure. The multi-disciplinary team is disseminating results throughout the international research community through open-source software and sensor board hardware as well as international summer schools and workshops.<br />

<br />
[[File:Wcps_framework.png|600px|thumb|right|Figure 1. WCPS Architecture]] <br />
<br />
As shown in the right figure, WCPS simulates<br />
the feedback control loop of the control system as follows.<br />
Sensor data is generated from structural models. Through a cross-platform function call from Simulink, sensor data is injected to the<br />
corresponding wireless sensors in TOSSIM. Following the routes<br />
and transmission schedule calculated by the network manager module,<br />
TOSSIM simulates the end-to-end wireless communication of<br />
the sensor data packets from the sensors to the base station, and<br />
then return the packet delay and loss to the Interfacing Block in<br />
Simulink through the Python interface. The Packet Collector module<br />
then extracts packet delivery information(the delay and loss)from the message pool. Sensor<br />
data and their loss and delay are then provided to the Data Block,<br />
which then feed the sensor data to the controller at the right time<br />
based on the packet delay (if the packet is not lost). WCPS utilizes<br />
basic API (e.g., the dos, UNIX command) of MATLAB to<br />
do cross-platform function calls. In TOSSIM, we re-implement a<br />
printf method in TinyOS to send simulation results to the<br />
Interfacing Block.<br />
<br />
User inputs to WCPS includes excitation signals to the structure<br />
(e.g., acceleration caused by earthquakes) and wireless traces used<br />
as input to TOSSIM. Excitation signal of the structure is provided<br />
to the structure models in the format of MAT files.<br />
The scheduler module calculates transmission schedules. Networking<br />
schedule is then deployed into the MAC layer code of<br />
wireless nodes and becomes effective after a TinyOS compilation.<br />
The TDMA MAC layer in WCPS is developed based on the MAC<br />
Layer Architecture (MLA) library and further adapted for<br />
TOSSIM under TinyOS 2.1.1. Received Signal Strength Indication(<br />
RSSI) and wireless noises traces are collected from real-world<br />
environments and provided to the wireless model used by TOSSIM<br />
for realistic wireless network simulations.<br />
The interfaces between the Simulink model<br />
and TOSSIM are encapsulated as two MATLAB embedded functions<br />
in Simulink: the Interfacing Block and the Data Block. The<br />
Interfacing Block extracts delay and loss information from TOSSIM<br />
messages, and the Data Block decides what data will be used for<br />
discrete control during each sampling period. The federated architecture<br />
of WCPS provides great flexibilities to incorporate different<br />
structural models and implement alternative scheduling-control<br />
approaches.<br />
<br />
== WCPS Capabilities ==<br />
<br />
This section briefly reviews application of WCPS in extensive Wireless Structural Control studies, which shows capability of WCPS enabling<br />
in-depth tradeoff among sensing synchronization, wireless network delays, as well as reliability of the wireless network. Specifically for the wireless network presented in this section,<br />
wireless traces in TOSSIM were collected from a 5-sensor testbed located at Bryan Hall of Washington University, as in Fig. 2. All results presented here uses the TDMA MAC layer.<br />
[[File:Building_network.png|200px|thumb|left|Figure. 2. Wireless Network in A Building]]<br />
<br />
[[File:Wcps building prr statistics.png|300px|thumb|right|Figure. 3. Network Statistics]]<br />
Fig. 3 shows end-to-end network ratio changes with different re-transmission mechanisms in WCPS.<br />
Sensor 1 has the lowest delivery ratio because it has a 2-hop route to the base station. Since OTDC-1<br />
does not perform any retransmission, while OTDC-2 and OTDC-3<br />
performs retransmit each packet once and twice, respectively. Under<br />
OTDC-1 Sensors 1 and 4 have delivery ratios of 70% and over 95%, respectively. As expected more retransmissions improve the<br />
deliver ratios of all sensors at the cost of longer delays as described earlier. <br />
<br />
[[File:Control perf building 1.png|300px|thumb|right|Figure 4. Tradeoff Among Data Synchronization, Network Reliability and Network Delay. ]]<br />
<br />
Fig. 4 shows changes of required resource for building control. Underlying tradeoffs are: better sensing synchronization vs. larger delays (e.g., OTDC-1 vs. SC), and <br />
larger network delays trading for better reliability (e.g., OTDC-3, OTDC-2 vs. OTDC-1). In Fig.4(a), OTDC-k approaches consistently require<br />
less control power than SC. As k increases, OTDC-k requires slightly less control power. Similarly, as shown in Fig. 2(b), OTDC-1 reduces control force by 80% when compared to SC. The<br />
differences in control force among different OTDC-k approaches are negligible. The results that OTDC-1 outperforms SC in both<br />
metrics indicate resource requirements are more sensitive to data synchronization than to sensing delays in this building control system.<br />
OTDC-k with larger k results in negligible reduction of control power and force, indicating resource requirements are not sensitive<br />
to network reliability in this case study.<br />
<br />
Fig. 5 shows control performance regarding structural response. In term of peak inter-story drift in Fig. 5(a), OTDC-<br />
k achieves more reduction in inter-story drift than SC. Interestingly, higher k in OTDC-k increases peak inter-story drift. Recall a higher k leads to higher communication reliability but longer<br />
sensing delay. Inter-story drift is thus more sensitive to sensing delays than to data loss in this case study. Similarly, as shown in Fig. 5(b), OTDC-3 causes worse peak acceleration than all the<br />
other approaches. Hence, building structural responses are more sensitive to sensing delays than to data loss. In addition, OTDC-1 only slightly outperforms SC, which indicates limited impact of<br />
data synchronization on structural response.<br />
<br />
[[File:Control perf building 2.png|300px|thumb|right|Figure 5. Tradeoff Among Data Synchronization, Network Reliability and Network Delay.]]<br />
WCPS has efficiently integrated TOSSIM and Simulink. Fig. 2-4 shows that there exist complex tradeoffs among data synchronization, sensing<br />
delay, and network reliability under realistic wireless structural control settings. A realistic, integrated wireless control simulator like WCPS is critical in exploring these design tradeoffs<br />
in wireless control design. Our cyber-physical simulation methodology and scheduling-control co-design approaches presented here not<br />
only represent a promising step toward smart civil infrastructure, but also provide useful insights and tools that can be generalized<br />
to other cyber-physical systems employing wireless control.<br />
<br />
==Environment Installation==<br />

reusable components that implement MAC layer logic on top of them. The MLA architecture can be used to develop a large number of platform-independent <br />
MAC implementations, with little or no further effort required to adapt these implementations to new hardware platforms. Our current implementation of MLA<br />
is built on top of TinyOS 2.1.1. It currently supports platforms which use the CC2420 radio stack and has been tested on TelosB motes. In addition to providing<br />
interfaces and components for building new MAC layer implementations, MLA includes implementations of five representative MAC layers. Specifically for WCPS, we <br />
adopt and further change the pure-TDMA MAC protocol for centralized data communication. <br />

Wireless Cyber-Physical Simulator (WCPS) is an open-source simulation environment for wireless control systems. By integrating Simulink and the TOSSIM wireless sensor simulator in a holistic simulation environment, WCPS accurately captures the dynamics of both the physical systems and the wireless sensor-actuator networks used for control. WCPS has been used for [http://research.engineering.wustl.edu/~boli/papers/iccps13.pdf realistic case studies of wireless structural control systems for civil infrastructure]. The broad application of WCPS is to support cyber-physical systems research on large-scale wireless control systems through high-fidelity joint cyber and physical simulations. This site includes the code release, tutorial, and simulation examples for wireless structural control systems. WCPS is developed as part of [http://bridge.cse.wustl.edu the cyber-physical systems project on wireless structural health monitoring and control systems], a collaborative effort by Washington University, Purdue and UIUC. <br />

Wireless Cyber-Physical Simulator (WCPS) is an open-source simulation environment for wireless control systems. By integrating Simulink and the TOSSIM wireless sensor simulator in a holistic simulation environment, WCPS accurately captures the dynamics of both the physical systems and the wireless sensor-actuator networks used for control. WCPS has been used for [http://research.engineering.wustl.edu/~boli/papers/iccps13.pdf realistic case studies of wireless structural control systems for civil infrastructure]. The broad application of WCPS is to support cyber-physical systems research on large-scale wireless control systems through high-fidelity joint cyber and physical simulations. This site includes the code release, tutorial, and simulation examples for wireless structural control systems. WCPS is developed as part of [http://bridge.cse.wustl.edu the cyber-physical systems project on wireless structural health monitoring and control systems], a collaborative effort by Washington University, Purdue and UIUC. <br />

== WCPS Architecture ==<br />
<br />
[[File:Wcps_framework.png|600px|thumb|right|Figure 1. WCPS Architecture]] <br />
<br />
As shown in the right figure, WCPS simulates<br />
the feedback control loop of the control system as follows.<br />
Sensor data is generated from structural models. Through a cross-platform function call from Simulink, sensor data is injected to the<br />
corresponding wireless sensors in TOSSIM. Following the routes<br />
and transmission schedule calculated by the network manager module,<br />
TOSSIM simulates the end-to-end wireless communication of<br />
the sensor data packets from the sensors to the base station, and<br />
then return the packet delay and loss to the Interfacing Block in<br />
Simulink through the Python interface. The Packet Collector module<br />
then extracts packet delivery information(the delay and loss)from the message pool. Sensor<br />
data and their loss and delay are then provided to the Data Block,<br />
which then feed the sensor data to the controller at the right time<br />
based on the packet delay (if the packet is not lost). WCPS utilizes<br />
basic API (e.g., the dos, UNIX command) of MATLAB to<br />
do cross-platform function calls. In TOSSIM, we re-implement a<br />
printf method in TinyOS to send simulation results to the<br />
Interfacing Block.<br />
<br />
User inputs to WCPS includes excitation signals to the structure<br />
(e.g., acceleration caused by earthquakes) and wireless traces used<br />
as input to TOSSIM. Excitation signal of the structure is provided<br />
to the structure models in the format of MAT files.<br />
The scheduler module calculates transmission schedules. Networking<br />
schedule is then deployed into the MAC layer code of<br />
wireless nodes and becomes effective after a TinyOS compilation.<br />
The TDMA MAC layer in WCPS is developed based on the MAC<br />
Layer Architecture (MLA) library and further adapted for<br />
TOSSIM under TinyOS 2.1.1. Received Signal Strength Indication(<br />
RSSI) and wireless noises traces are collected from real-world<br />
environments and provided to the wireless model used by TOSSIM<br />
for realistic wireless network simulations.<br />
The interfaces between the Simulink model<br />
and TOSSIM are encapsulated as two MATLAB embedded functions<br />
in Simulink: the Interfacing Block and the Data Block. The<br />
Interfacing Block extracts delay and loss information from TOSSIM<br />
messages, and the Data Block decides what data will be used for<br />
discrete control during each sampling period. The federated architecture<br />
of WCPS provides great flexibilities to incorporate different<br />
structural models and implement alternative scheduling-control<br />
approaches.<br />
<br />
== WCPS Capabilities ==<br />
<br />
This section briefly reviews application of WCPS in extensive Wireless Structural Control studies, which shows capability of WCPS enabling<br />
in-depth tradeoff among sensing synchronization, wireless network delays, as well as reliability of the wireless network. Specifically for the wireless network presented in this section,<br />
wireless traces in TOSSIM were collected from a 5-sensor testbed located at Bryan Hall of Washington University, as in Fig. 2. All results presented here uses the TDMA MAC layer.<br />
[[File:Building_network.png|200px|thumb|left|Figure. 2. Wireless Network in A Building]]<br />
<br />
[[File:Wcps building prr statistics.png|300px|thumb|right|Figure. 3. Network Statistics]]<br />
Fig. 3 shows end-to-end network ratio changes with different re-transmission mechanisms in WCPS.<br />
Sensor 1 has the lowest delivery ratio because it has a 2-hop route to the base station. Since OTDC-1<br />
does not perform any retransmission, while OTDC-2 and OTDC-3<br />
performs retransmit each packet once and twice, respectively. Under<br />
OTDC-1 Sensors 1 and 4 have delivery ratios of 70% and over 95%, respectively. As expected more retransmissions improve the<br />
deliver ratios of all sensors at the cost of longer delays as described earlier. <br />
<br />
[[File:Control perf building 1.png|300px|thumb|right|Figure 4. Tradeoff Among Data Synchronization, Network Reliability and Network Delay. ]]<br />
<br />
Fig. 4 shows changes of required resource for building control. Underlying tradeoffs are: better sensing synchronization vs. larger delays (e.g., OTDC-1 vs. SC), and <br />
larger network delays trading for better reliability (e.g., OTDC-3, OTDC-2 vs. OTDC-1). In Fig.4(a), OTDC-k approaches consistently require<br />
less control power than SC. As k increases, OTDC-k requires slightly less control power. Similarly, as shown in Fig. 2(b), OTDC-1 reduces control force by 80% when compared to SC. The<br />
differences in control force among different OTDC-k approaches are negligible. The results that OTDC-1 outperforms SC in both<br />
metrics indicate resource requirements are more sensitive to data synchronization than to sensing delays in this building control system.<br />
OTDC-k with larger k results in negligible reduction of control power and force, indicating resource requirements are not sensitive<br />
to network reliability in this case study.<br />
<br />
Fig. 5 shows control performance regarding structural response. In term of peak inter-story drift in Fig. 5(a), OTDC-<br />
k achieves more reduction in inter-story drift than SC. Interestingly, higher k in OTDC-k increases peak inter-story drift. Recall a higher k leads to higher communication reliability but longer<br />
sensing delay. Inter-story drift is thus more sensitive to sensing delays than to data loss in this case study. Similarly, as shown in Fig. 5(b), OTDC-3 causes worse peak acceleration than all the<br />
other approaches. Hence, building structural responses are more sensitive to sensing delays than to data loss. In addition, OTDC-1 only slightly outperforms SC, which indicates limited impact of<br />
data synchronization on structural response.<br />
<br />
[[File:Control perf building 2.png|300px|thumb|right|Figure 5. Tradeoff Among Data Synchronization, Network Reliability and Network Delay.]]<br />
WCPS has efficiently integrated TOSSIM and Simulink. Fig. 2-4 shows that there exist complex tradeoffs among data synchronization, sensing<br />
delay, and network reliability under realistic wireless structural control settings. A realistic, integrated wireless control simulator like WCPS is critical in exploring these design tradeoffs<br />
in wireless control design. Our cyber-physical simulation methodology and scheduling-control co-design approaches presented here not<br />
only represent a promising step toward smart civil infrastructure, but also provide useful insights and tools that can be generalized<br />
to other cyber-physical systems employing wireless control.<br />
<br />
==Environment Installation==<br />
* Install TinyOS<br />
<br />
<pre><br />
WCPS is implemented and tested on MacOS X (snowleopard), Windows XP, and Windows 7. Current release of WCPS is under TinyOS 2.1.1, which can be installed following the two methods.<br />
</pre><br />
* Follow the TinyOS official tutorial on installation of TinyOS for your specific platform: [http://docs.tinyos.net/tinywiki/index.php/Getting_started#User_Contributed_Methods Link]<br />
* Directly download the pre-tested TinyOS 2.1.1 image from here: [http://research.engineering.wustl.edu/~boli/downloads/tinyos-2.1.1.dmg TinyOS2.1.1 for SnowLeopard(and possibly later versions)] [Cygwin package coming soon.]<br />
<br />
* Install Mac Layer Architecture(MLA)<br />
<pre><br />
The MAC Layer Architecture (MLA) provides a component-based architecture for MAC protocols in wireless sensor networks. MLA extends the Unified Power <br />
Management Architecture to provide the hardware-independent interfaces required by timing sensitive MAC protocols, and defines platform-independent <br />
reusable components that implement MAC layer logic on top of them. The MLA architecture can be used to develop a large number of platform-independent <br />
MAC implementations, with little or no further effort required to adapt these implementations to new hardware platforms. Our current implementation of MLA<br />
is built on top of TinyOS 2.1.1. It currently supports platforms which use the CC2420 radio stack and has been tested on TelosB motes. In addition to providing<br />
interfaces and components for building new MAC layer implementations, MLA includes implementations of five representative MAC layers. Specifically for WCPS, we <br />
adopt and further change the pure-TDMA MAC protocol for centralized data communication. <br />
</pre><br />
<br />
* Follow the instructions here: [http://wsn.cse.wustl.edu/index.php?title=MAC_Layer_Architecture Install MLA].<br />
<br />
* Install MATLAB and Simulink<br />
* If you already have MATLAB MATLAB 7.11.0.584 (2010b) or later version, skip this step. Otherwise, follow the tutorial here: [http://www.mathworks.com/help/install/index.html install MATLAB]<br />
<br />
* Install Python<br />
If you already have Python 2.7.2 or later version installed, skip this step. Otherwise, follow the manual here: [http://www.python.org/getit/ install Python]<br />
<br />
== Download WCPS ==<br />
* [http://research.engineering.wustl.edu/~boli/downloads/cygwin.zip A complete package of Cygwin with TinyOS 2.1.1, MLA, TOSSIM pre-installed] with a [http://research.engineering.wustl.edu/~boli/downloads/WCPS_Cygwin_Installation_Usage_Tutorial.txt WCPS Cygwin Installation & Usage Tutorial]<br />

<br />
== Use WCPS ==<br />
<br />
Wireless network plays a critical role in close-loop wireless control system. Sitting on top of WCPS, simulating <br />
a wireless TDMA network is as easy as collecting these NesC files below:<br />
<br />
* "Makefile" takes advantage of the fact that it's not necessary to recompile all the files not changed while specifying all necessary libraries.<br />
* "TestNetwork.h" defines necessary message structures for the wireless communication.<br />
* "TestNetworkAppC.nc" connects claimed application interfaces to interfaces that are defined in the hardware library.<br />
* "TestNetworkC.nc" implements send/receive functionality of a wireless node.<br />
* "tossim-call.py" configures TOSSIM network and does packet injection into the Tossim network.[http://research.engineering.wustl.edu/~boli/downloads/TinyosFiles.zip All above necessary files.].<br />
* Re-implemented TOSSIM libraries for TDMA simulation.[http://research.engineering.wustl.edu/~boli/downloads/pure-tdma.zip TDMA components for TOSSIM.].<br />
* Wireless traces: [http://research.engineering.wustl.edu/~boli/downloads/building_noise_n_rssi.zip Traces for 5-sensor wireless network in a building].<br />
<br />
Put all the above files into the same folder, prompt a terminal (or a Cygwin window), and in the terminal run <br />
<pre><br />
Make micaz sim<br />
</pre><br />
<br />
If TinyOS and python is configured correctly, go ahead and run in the terminal:<br />
<pre><br />
./tossim-call.py<br />
</pre><br />
<br />
Having collected aforementioned TinyOS files, a simplified example that uses key networking Interfacing Block and Data Block of WCPS is shown in Fig. 6.<br />
[[File:Simple_wcps_example.png|500px|thumb|center|Figure 6. A Simple Example that uses Interfacing and Data Block of WCPS. ]]<br />
<br />
This examples shows:<br />
<br />
* How input data in Simulink is injected to TOSSIM network; <br />
* How TOSSIM Interfacing Block runs as a Matlab Embedded function; <br />
* What type of data is output from the Interfacing Block;<br />
* How data usage strategies are applied to the data in the Data Block.<br />
* What type of data is eventually output from the Data Block and provided for future control use.<br />
<br />
Source code for the example can be found [http://research.engineering.wustl.edu/~boli/downloads/simple_example.zip here].<br />

<br />
* Install Mac Layer Architecture(MLA)<br />
<pre><br />
The MAC Layer Architecture (MLA) provides a component-based architecture for MAC protocols in wireless sensor networks. MLA extends the Unified Power <br />
Management Architecture to provide the hardware-independent interfaces required by timing sensitive MAC protocols, and defines platform-independent <br />
reusable components that implement MAC layer logic on top of them. The MLA architecture can be used to develop a large number of platform-independent <br />
MAC implementations, with little or no further effort required to adapt these implementations to new hardware platforms. Our current implementation of MLA<br />
is built on top of TinyOS 2.1.1. It currently supports platforms which use the CC2420 radio stack and has been tested on TelosB motes. In addition to providing<br />
interfaces and components for building new MAC layer implementations, MLA includes implementations of five representative MAC layers. Specifically for WCPS, we <br />
adopt and further change the pure-TDMA MAC protocol for centralized data communication. <br />
</pre><br />
<br />
* Follow the instructions here: [http://wsn.cse.wustl.edu/index.php?title=MAC_Layer_Architecture Install MLA].<br />

Wireless Cyber-Physical Simulator (WCPS) is an open-source simulation environment for wireless control systems. By integrating Simulink and the TOSSIM wireless sensor simulator in a holistic simulation environment, WCPS accurately captures the dynamics of both the physical systems and the wireless sensor-actuator networks used for control. WCPS has been used for [http://research.engineering.wustl.edu/~boli/papers/iccps13.pdf realistic case studies of wireless structural control systems for civil infrastructure]. The broad application of WCPS is to support cyber-physical systems research on large-scale wireless control systems through high-fidelity joint cyber and physical simulations. This site includes the code release, tutorial, and simulation examples for wireless structural control systems. WCPS is developed as part of [http://bridge.cse.wustl.edu the cyber-physical systems project on wireless structural health monitoring and control systems], a collaborative effort by Washington University, Purdue and UIUC. <br />

== WCPS Architecture ==<br />
<br />
[[File:Wcps_framework.png|600px|thumb|right|Figure 1. WCPS Architecture]] <br />
<br />
As shown in the right figure, WCPS simulates<br />
the feedback control loop of the control system as follows.<br />
Sensor data is generated from structural models. Through a cross-platform function call from Simulink, sensor data is injected to the<br />
corresponding wireless sensors in TOSSIM. Following the routes<br />
and transmission schedule calculated by the network manager module,<br />
TOSSIM simulates the end-to-end wireless communication of<br />
the sensor data packets from the sensors to the base station, and<br />
then return the packet delay and loss to the Interfacing Block in<br />
Simulink through the Python interface. The Packet Collector module<br />
then extracts packet delivery information(the delay and loss)from the message pool. Sensor<br />
data and their loss and delay are then provided to the Data Block,<br />
which then feed the sensor data to the controller at the right time<br />
based on the packet delay (if the packet is not lost). WCPS utilizes<br />
basic API (e.g., the dos, UNIX command) of MATLAB to<br />
do cross-platform function calls. In TOSSIM, we re-implement a<br />
printf method in TinyOS to send simulation results to the<br />
Interfacing Block.<br />
<br />
User inputs to WCPS includes excitation signals to the structure<br />
(e.g., acceleration caused by earthquakes) and wireless traces used<br />
as input to TOSSIM. Excitation signal of the structure is provided<br />
to the structure models in the format of MAT files.<br />
The scheduler module calculates transmission schedules. Networking<br />
schedule is then deployed into the MAC layer code of<br />
wireless nodes and becomes effective after a TinyOS compilation.<br />
The TDMA MAC layer in WCPS is developed based on the MAC<br />
Layer Architecture (MLA) library and further adapted for<br />
TOSSIM under TinyOS 2.1.1. Received Signal Strength Indication(<br />
RSSI) and wireless noises traces are collected from real-world<br />
environments and provided to the wireless model used by TOSSIM<br />
for realistic wireless network simulations.<br />
The interfaces between the Simulink model<br />
and TOSSIM are encapsulated as two MATLAB embedded functions<br />
in Simulink: the Interfacing Block and the Data Block. The<br />
Interfacing Block extracts delay and loss information from TOSSIM<br />
messages, and the Data Block decides what data will be used for<br />
discrete control during each sampling period. The federated architecture<br />
of WCPS provides great flexibilities to incorporate different<br />
structural models and implement alternative scheduling-control<br />
approaches.<br />
<br />
== WCPS Capabilities ==<br />
<br />
This section briefly reviews application of WCPS in extensive Wireless Structural Control studies, which shows capability of WCPS enabling<br />
in-depth tradeoff among sensing synchronization, wireless network delays, as well as reliability of the wireless network. Specifically for the wireless network presented in this section,<br />
wireless traces in TOSSIM were collected from a 5-sensor testbed located at Bryan Hall of Washington University, as in Fig. 2. All results presented here uses the TDMA MAC layer.<br />
[[File:Building_network.png|200px|thumb|left|Figure. 2. Wireless Network in A Building]]<br />
<br />
[[File:Wcps building prr statistics.png|300px|thumb|right|Figure. 3. Network Statistics]]<br />
Fig. 3 shows end-to-end network ratio changes with different re-transmission mechanisms in WCPS.<br />
Sensor 1 has the lowest delivery ratio because it has a 2-hop route to the base station. Since OTDC-1<br />
does not perform any retransmission, while OTDC-2 and OTDC-3<br />
performs retransmit each packet once and twice, respectively. Under<br />
OTDC-1 Sensors 1 and 4 have delivery ratios of 70% and over 95%, respectively. As expected more retransmissions improve the<br />
deliver ratios of all sensors at the cost of longer delays as described earlier. <br />
<br />
[[File:Control perf building 1.png|300px|thumb|right|Figure 4. Tradeoff Among Data Synchronization, Network Reliability and Network Delay. ]]<br />
<br />
Fig. 4 shows changes of required resource for building control. Underlying tradeoffs are: better sensing synchronization vs. larger delays (e.g., OTDC-1 vs. SC), and <br />
larger network delays trading for better reliability (e.g., OTDC-3, OTDC-2 vs. OTDC-1). In Fig.4(a), OTDC-k approaches consistently require<br />
less control power than SC. As k increases, OTDC-k requires slightly less control power. Similarly, as shown in Fig. 2(b), OTDC-1 reduces control force by 80% when compared to SC. The<br />
differences in control force among different OTDC-k approaches are negligible. The results that OTDC-1 outperforms SC in both<br />
metrics indicate resource requirements are more sensitive to data synchronization than to sensing delays in this building control system.<br />
OTDC-k with larger k results in negligible reduction of control power and force, indicating resource requirements are not sensitive<br />
to network reliability in this case study.<br />
<br />
Fig. 5 shows control performance regarding structural response. In term of peak inter-story drift in Fig. 5(a), OTDC-<br />
k achieves more reduction in inter-story drift than SC. Interestingly, higher k in OTDC-k increases peak inter-story drift. Recall a higher k leads to higher communication reliability but longer<br />
sensing delay. Inter-story drift is thus more sensitive to sensing delays than to data loss in this case study. Similarly, as shown in Fig. 5(b), OTDC-3 causes worse peak acceleration than all the<br />
other approaches. Hence, building structural responses are more sensitive to sensing delays than to data loss. In addition, OTDC-1 only slightly outperforms SC, which indicates limited impact of<br />
data synchronization on structural response.<br />
<br />
[[File:Control perf building 2.png|300px|thumb|right|Figure 5. Tradeoff Among Data Synchronization, Network Reliability and Network Delay.]]<br />
WCPS has efficiently integrated TOSSIM and Simulink. Fig. 2-4 shows that there exist complex tradeoffs among data synchronization, sensing<br />
delay, and network reliability under realistic wireless structural control settings. A realistic, integrated wireless control simulator like WCPS is critical in exploring these design tradeoffs<br />
in wireless control design. Our cyber-physical simulation methodology and scheduling-control co-design approaches presented here not<br />
only represent a promising step toward smart civil infrastructure, but also provide useful insights and tools that can be generalized<br />
to other cyber-physical systems employing wireless control.<br />

in-depth tradeoff among sensing synchronization, wireless network delays, as well as reliability of the wireless network. Specifically for the wireless network presented in this section,<br />
wireless traces in TOSSIM were collected from a 5-sensor testbed located at Bryan Hall of Washington University, as in Fig. 2. All results presented here uses the TDMA MAC layer.<br />

Fig. 3 shows end-to-end network ratio changes with different re-transmission mechanisms in WCPS.<br />
Sensor 1 has the lowest delivery ratio because it has a 2-hop route to the base station. Since OTDC-1<br />
does not perform any retransmission, while OTDC-2 and OTDC-3<br />
performs retransmit each packet once and twice, respectively. Under<br />
OTDC-1 Sensors 1 and 4 have delivery ratios of 70% and over 95%, respectively. As expected more retransmissions improve the<br />
deliver ratios of all sensors at the cost of longer delays as described earlier. <br />
<br />
[[File:Control perf building 1.png|300px|thumb|right|Figure 4. Tradeoff Among Data Synchronization, Network Reliability and Network Delay. ]]<br />
<br />
Fig. 4 shows changes of required resource for building control. Underlying tradeoffs are: better sensing synchronization vs. larger delays (e.g., OTDC-1 vs. SC), and <br />
larger network delays trading for better reliability (e.g., OTDC-3, OTDC-2 vs. OTDC-1). In Fig.4(a), OTDC-k approaches consistently require<br />
less control power than SC. As k increases, OTDC-k requires slightly less control power. Similarly, as shown in Fig. 2(b), OTDC-1 reduces control force by 80% when compared to SC. The<br />
differences in control force among different OTDC-k approaches are negligible. The results that OTDC-1 outperforms SC in both<br />
metrics indicate resource requirements are more sensitive to data synchronization than to sensing delays in this building control system.<br />
OTDC-k with larger k results in negligible reduction of control power and force, indicating resource requirements are not sensitive<br />
to network reliability in this case study.<br />
<br />
Fig. 5 shows control performance regarding structural response. In term of peak inter-story drift in Fig. 5(a), OTDC-<br />
k achieves more reduction in inter-story drift than SC. Interestingly, higher k in OTDC-k increases peak inter-story drift. Recall a higher k leads to higher communication reliability but longer<br />
sensing delay. Inter-story drift is thus more sensitive to sensing delays than to data loss in this case study. Similarly, as shown in Fig. 5(b), OTDC-3 causes worse peak acceleration than all the<br />
other approaches. Hence, building structural responses are more sensitive to sensing delays than to data loss. In addition, OTDC-1 only slightly outperforms SC, which indicates limited impact of<br />
data synchronization on structural response.<br />
<br />
[[File:Control perf building 2.png|300px|thumb|right|Figure 5. Tradeoff Among Data Synchronization, Network Reliability and Network Delay.]]<br />
WCPS has efficiently integrated TOSSIM and Simulink. Fig. 2-4 shows that there exist complex tradeoffs among data synchronization, sensing<br />
delay, and network reliability under realistic wireless structural control settings. A realistic, integrated wireless control simulator like WCPS is critical in exploring these design tradeoffs<br />
in wireless control design. Our cyber-physical simulation methodology and scheduling-control co-design approaches presented here not<br />
only represent a promising step toward smart civil infrastructure, but also provide useful insights and tools that can be generalized<br />
to other cyber-physical systems employing wireless control.<br />
<br />
==Environment Installation==<br />
* Install TinyOS<br />
<br />
<pre><br />
WCPS is implemented and tested on MacOS X (snowleopard), Windows XP, and Windows 7. Current release of WCPS is under TinyOS 2.1.1, which can be installed following the two methods.<br />
</pre><br />
* Follow the TinyOS official tutorial on installation of TinyOS for your specific platform: [http://docs.tinyos.net/tinywiki/index.php/Getting_started#User_Contributed_Methods Link]<br />
* Directly download the pre-tested TinyOS 2.1.1 image from here: [http://research.engineering.wustl.edu/~boli/downloads/tinyos-2.1.1.dmg TinyOS2.1.1 for SnowLeopard(and possibly later versions)] [Cygwin package coming soon.]<br />
<br />
* Install Mac Layer Architecture(MLA)<br />
<pre><br />
The MAC Layer Architecture (MLA) provides a component-based architecture for MAC protocols in wireless sensor networks. MLA extends the Unified Power <br />
Management Architecture to provide the hardware-independent interfaces required by timing sensitive MAC protocols, and defines platform-independent <br />
reusable components that implement MAC layer logic on top of them. The MLA architecture can be used to develop a large number of platform-independent <br />
MAC implementations, with little or no further effort required to adapt these implementations to new hardware platforms. Our current implementation of MLA<br />
is built on top of TinyOS 2.1.1. It currently supports platforms which use the CC2420 radio stack and has been tested on TelosB motes. In addition to providing<br />
interfaces and components for building new MAC layer implementations, MLA includes implementations of five representative MAC layers. Specifically for WCPS, we <br />
adopt and further change the pure-TDMA MAC protocol for centralized data communication. <br />
</pre><br />
<br />
* Follow the instructions here: [http://wsn.cse.wustl.edu/index.php?title=MAC_Layer_Architecture Install MLA].<br />
<br />
* Install MATLAB and Simulink<br />
* If you already have MATLAB MATLAB 7.11.0.584 (2010b) or later version, skip this step. Otherwise, follow the tutorial here: [http://www.mathworks.com/help/install/index.html install MATLAB]<br />
<br />
* Install Python<br />
If you already have Python 2.7.2 or later version installed, skip this step. Otherwise, follow the manual here: [http://www.python.org/getit/ install Python]<br />
<br />
== Download WCPS ==<br />
* [http://research.engineering.wustl.edu/~boli/downloads/cygwin.zip A complete package of Cygwin with TinyOS 2.1.1, MLA, TOSSIM pre-installed] with a [http://research.engineering.wustl.edu/~boli/downloads/WCPS_Cygwin_Installation_Usage_Tutorial.txt WCPS Cygwin Installation & Usage Tutorial]<br />
* [http://research.engineering.wustl.edu/~boli/downloads/wcpsv0.1.1.zip WCPS v0.1.1 and four extensive case studies] for [http://research.engineering.wustl.edu/~boli/papers/iccps13.pdf ICCPS'13 paper]<br />
<br />
== Use WCPS ==<br />
<br />
Wireless network plays a critical role in close-loop wireless control system. Sitting on top of WCPS, simulating <br />
a wireless TDMA network is as easy as collecting these NesC files below:<br />
<br />
* "Makefile" takes advantage of the fact that it's not necessary to recompile all the files not changed while specifying all necessary libraries.<br />
* "TestNetwork.h" defines necessary message structures for the wireless communication.<br />
* "TestNetworkAppC.nc" connects claimed application interfaces to interfaces that are defined in the hardware library.<br />
* "TestNetworkC.nc" implements send/receive functionality of a wireless node.<br />
* "tossim-call.py" configures TOSSIM network and does packet injection into the Tossim network.[http://research.engineering.wustl.edu/~boli/downloads/TinyosFiles.zip All above necessary files.].<br />
* Re-implemented TOSSIM libraries for TDMA simulation.[http://research.engineering.wustl.edu/~boli/downloads/pure-tdma.zip TDMA components for TOSSIM.].<br />
* Wireless traces: [http://research.engineering.wustl.edu/~boli/downloads/building_noise_n_rssi.zip Traces for 5-sensor wireless network in a building].<br />
<br />
Put all the above files into the same folder, prompt a terminal (or a Cygwin window), and in the terminal run <br />
<pre><br />
Make micaz sim<br />
</pre><br />
<br />
If TinyOS and python is configured correctly, go ahead and run in the terminal:<br />
<pre><br />
./tossim-call.py<br />
</pre><br />
<br />
Having collected aforementioned TinyOS files, a simplified example that uses key networking Interfacing Block and Data Block of WCPS is shown in Fig. 6.<br />
[[File:Simple_wcps_example.png|500px|thumb|center|Figure 6. A Simple Example that uses Interfacing and Data Block of WCPS. ]]<br />
<br />
This examples shows:<br />
<br />
* How input data in Simulink is injected to TOSSIM network; <br />
* How TOSSIM Interfacing Block runs as a Matlab Embedded function; <br />
* What type of data is output from the Interfacing Block;<br />
* How data usage strategies are applied to the data in the Data Block.<br />
* What type of data is eventually output from the Data Block and provided for future control use.<br />
<br />
Source code for the example can be found [http://research.engineering.wustl.edu/~boli/downloads/simple_example.zip here].<br />
To run this integrated example, simply download, unzip the source code, and run Run_delay_data_func.m in Matlab.<br />

Wireless Cyber-Physical Simulator (WCPS) is an open-source simulation environment for wireless control systems. By integrating Simulink and the TOSSIM wireless sensor simulator in a holistic simulation environment, WCPS accurately captures the dynamics of both the physical systems and the wireless sensor-actuator networks used for control. WCPS has been used for [http://research.engineering.wustl.edu/~boli/papers/iccps13.pdf realistic case studies of wireless structural control systems for civil infrastructure]. The broad application of WCPS is to support cyber-physical systems research on large-scale wireless control systems through high-fidelity joint cyber and physical simulations. This site includes the code release, tutorial, and simulation examples for wireless structural control systems. WCPS is developed as part of [http://bridge.cse.wustl.edu the cyber-physical systems project on wireless structural health monitoring and control systems], a collaborative effort by Washington University, Purdue and UIUC. <br />

== WCPS Architecture ==<br />
<br />
[[File:Wcps_framework.png|600px|thumb|right|Figure 1. WCPS Architecture]] <br />
<br />
As shown in the right figure, WCPS simulates<br />
the feedback control loop of the control system as follows.<br />
Sensor data is generated from structural models. Through a cross-platform function call from Simulink, sensor data is injected to the<br />
corresponding wireless sensors in TOSSIM. Following the routes<br />
and transmission schedule calculated by the network manager module,<br />
TOSSIM simulates the end-to-end wireless communication of<br />
the sensor data packets from the sensors to the base station, and<br />
then return the packet delay and loss to the Interfacing Block in<br />
Simulink through the Python interface. The Packet Collector module<br />
then extracts packet delivery information(the delay and loss)from the message pool. Sensor<br />
data and their loss and delay are then provided to the Data Block,<br />
which then feed the sensor data to the controller at the right time<br />
based on the packet delay (if the packet is not lost). WCPS utilizes<br />
basic API (e.g., the dos, UNIX command) of MATLAB to<br />
do cross-platform function calls. In TOSSIM, we re-implement a<br />
printf method in TinyOS to send simulation results to the<br />
Interfacing Block.<br />
<br />
User inputs to WCPS includes excitation signals to the structure<br />
(e.g., acceleration caused by earthquakes) and wireless traces used<br />
as input to TOSSIM. Excitation signal of the structure is provided<br />
to the structure models in the format of MAT files.<br />
The scheduler module calculates transmission schedules. Networking<br />
schedule is then deployed into the MAC layer code of<br />
wireless nodes and becomes effective after a TinyOS compilation.<br />
The TDMA MAC layer in WCPS is developed based on the MAC<br />
Layer Architecture (MLA) library and further adapted for<br />
TOSSIM under TinyOS 2.1.1. Received Signal Strength Indication(<br />
RSSI) and wireless noises traces are collected from real-world<br />
environments and provided to the wireless model used by TOSSIM<br />
for realistic wireless network simulations.<br />
The interfaces between the Simulink model<br />
and TOSSIM are encapsulated as two MATLAB embedded functions<br />
in Simulink: the Interfacing Block and the Data Block. The<br />
Interfacing Block extracts delay and loss information from TOSSIM<br />
messages, and the Data Block decides what data will be used for<br />
discrete control during each sampling period. The federated architecture<br />
of WCPS provides great flexibilities to incorporate different<br />
structural models and implement alternative scheduling-control<br />
approaches.<br />
<br />
== WCPS Capabilities ==<br />
<br />
This section briefly reviews application of WCPS in extensive Wireless Structural Control studies, which shows capability of WCPS enabling<br />
in-depth tradeoff among sensing synchronization, wireless network delays, as well as reliability of the wireless network. Specifically for the wireless network presented in this section,<br />
wireless traces in TOSSIM were collected from a 5-sensor testbed located at Bryan Hall of Washington University, as in Fig. 2. All results presented here uses the TDMA MAC layer.<br />
[[File:Building_network.png|200px|thumb|left|Figure. 2. Wireless Network in A Building]]<br />
<br />
[[File:Wcps building prr statistics.png|300px|thumb|right|Figure. 3. Network Statistics]]<br />
Fig. 3 shows end-to-end network ratio changes with different re-transmission mechanisms in WCPS.<br />
Sensor 1 has the lowest delivery ratio because it has a 2-hop route to the base station. Since OTDC-1<br />
does not perform any retransmission, while OTDC-2 and OTDC-3<br />
performs retransmit each packet once and twice, respectively. Under<br />
OTDC-1 Sensors 1 and 4 have delivery ratios of 70% and over 95%, respectively. As expected more retransmissions improve the<br />
deliver ratios of all sensors at the cost of longer delays as described earlier. <br />
<br />
[[File:Control perf building 1.png|300px|thumb|right|Figure 4. Tradeoff Among Data Synchronization, Network Reliability and Network Delay. ]]<br />
<br />
Fig. 4 shows changes of required resource for building control. Underlying tradeoffs are: better sensing synchronization vs. larger delays (e.g., OTDC-1 vs. SC), and <br />
larger network delays trading for better reliability (e.g., OTDC-3, OTDC-2 vs. OTDC-1). In Fig.4(a), OTDC-k approaches consistently require<br />
less control power than SC. As k increases, OTDC-k requires slightly less control power. Similarly, as shown in Fig. 2(b), OTDC-1 reduces control force by 80% when compared to SC. The<br />
differences in control force among different OTDC-k approaches are negligible. The results that OTDC-1 outperforms SC in both<br />
metrics indicate resource requirements are more sensitive to data synchronization than to sensing delays in this building control system.<br />
OTDC-k with larger k results in negligible reduction of control power and force, indicating resource requirements are not sensitive<br />
to network reliability in this case study.<br />
<br />
Fig. 5 shows control performance regarding structural response. In term of peak inter-story drift in Fig. 5(a), OTDC-<br />
k achieves more reduction in inter-story drift than SC. Interestingly, higher k in OTDC-k increases peak inter-story drift. Recall a higher k leads to higher communication reliability but longer<br />
sensing delay. Inter-story drift is thus more sensitive to sensing delays than to data loss in this case study. Similarly, as shown in Fig. 5(b), OTDC-3 causes worse peak acceleration than all the<br />
other approaches. Hence, building structural responses are more sensitive to sensing delays than to data loss. In addition, OTDC-1 only slightly outperforms SC, which indicates limited impact of<br />
data synchronization on structural response.<br />
<br />
[[File:Control perf building 2.png|300px|thumb|right|Figure 5. Tradeoff Among Data Synchronization, Network Reliability and Network Delay.]]<br />
WCPS has efficiently integrated TOSSIM and Simulink. Fig. 2-4 shows that there exist complex tradeoffs among data synchronization, sensing<br />
delay, and network reliability under realistic wireless structural control settings. A realistic, integrated wireless control simulator like WCPS is critical in exploring these design tradeoffs<br />
in wireless control design. Our cyber-physical simulation methodology and scheduling-control co-design approaches presented here not<br />
only represent a promising step toward smart civil infrastructure, but also provide useful insights and tools that can be generalized<br />
to other cyber-physical systems employing wireless control.<br />
<br />
==Environment Installation==<br />
* Install TinyOS<br />
<br />
<pre><br />
WCPS is implemented and tested on MacOS X (snowleopard), Windows XP, and Windows 7. Current release of WCPS is under TinyOS 2.1.1, which can be installed following the two methods.<br />
</pre><br />
* Follow the TinyOS official tutorial on installation of TinyOS for your specific platform: [http://docs.tinyos.net/tinywiki/index.php/Getting_started#User_Contributed_Methods Link]<br />
* Directly download the pre-tested TinyOS 2.1.1 image from here: [http://research.engineering.wustl.edu/~boli/downloads/tinyos-2.1.1.dmg TinyOS2.1.1 for SnowLeopard(and possibly later versions)] [Cygwin package coming soon.]<br />
<br />
* Install Mac Layer Architecture(MLA)<br />
<pre><br />
The MAC Layer Architecture (MLA) provides a component-based architecture for MAC protocols in wireless sensor networks. MLA extends the Unified Power <br />
Management Architecture to provide the hardware-independent interfaces required by timing sensitive MAC protocols, and defines platform-independent <br />
reusable components that implement MAC layer logic on top of them. The MLA architecture can be used to develop a large number of platform-independent <br />
MAC implementations, with little or no further effort required to adapt these implementations to new hardware platforms. Our current implementation of MLA<br />
is built on top of TinyOS 2.1.1. It currently supports platforms which use the CC2420 radio stack and has been tested on TelosB motes. In addition to providing<br />
interfaces and components for building new MAC layer implementations, MLA includes implementations of five representative MAC layers. Specifically for WCPS, we <br />
adopt and further change the pure-TDMA MAC protocol for centralized data communication. <br />
</pre><br />
<br />
* Follow the instructions here: [http://wsn.cse.wustl.edu/index.php?title=MAC_Layer_Architecture Install MLA].<br />
<br />
* Install MATLAB and Simulink<br />
* If you already have MATLAB MATLAB 7.11.0.584 (2010b) or later version, skip this step. Otherwise, follow the tutorial here: [http://www.mathworks.com/help/install/index.html install MATLAB]<br />
<br />
* Install Python<br />
If you already have Python 2.7.2 or later version installed, skip this step. Otherwise, follow the manual here: [http://www.python.org/getit/ install Python]<br />
<br />
== Download WCPS ==<br />
* [http://research.engineering.wustl.edu/~boli/downloads/cygwin.zip A complete package of Cygwin with TinyOS 2.1.1, MLA, TOSSIM pre-installed] with a [http://research.engineering.wustl.edu/~boli/downloads/WCPS_Cygwin_Installation_Usage_Tutorial.txt WCPS Cygwin Installation & Usage Tutorial]<br />

<br />
== Use WCPS ==<br />
<br />
Wireless network plays a critical role in close-loop wireless control system. Sitting on top of WCPS, simulating <br />
a wireless TDMA network is as easy as collecting these NesC files below:<br />
<br />
* "Makefile" takes advantage of the fact that it's not necessary to recompile all the files not changed while specifying all necessary libraries.<br />
* "TestNetwork.h" defines necessary message structures for the wireless communication.<br />
* "TestNetworkAppC.nc" connects claimed application interfaces to interfaces that are defined in the hardware library.<br />
* "TestNetworkC.nc" implements send/receive functionality of a wireless node.<br />
* "tossim-call.py" configures TOSSIM network and does packet injection into the Tossim network.[http://research.engineering.wustl.edu/~boli/downloads/TinyosFiles.zip All above necessary files.].<br />
* Re-implemented TOSSIM libraries for TDMA simulation.[http://research.engineering.wustl.edu/~boli/downloads/pure-tdma.zip TDMA components for TOSSIM.].<br />
* Wireless traces: [http://research.engineering.wustl.edu/~boli/downloads/building_noise_n_rssi.zip Traces for 5-sensor wireless network in a building].<br />
<br />
Put all the above files into the same folder, prompt a terminal (or a Cygwin window), and in the terminal run <br />
<pre><br />
Make micaz sim<br />
</pre><br />
<br />
If TinyOS and python is configured correctly, go ahead and run in the terminal:<br />
<pre><br />
./tossim-call.py<br />
</pre><br />
<br />
Having collected aforementioned TinyOS files, a simplified example that uses key networking Interfacing Block and Data Block of WCPS is shown in Fig. 6.<br />
[[File:Simple_wcps_example.png|500px|thumb|center|Figure 6. A Simple Example that uses Interfacing and Data Block of WCPS. ]]<br />
<br />
This examples shows:<br />
<br />
* How input data in Simulink is injected to TOSSIM network; <br />
* How TOSSIM Interfacing Block runs as a Matlab Embedded function; <br />
* What type of data is output from the Interfacing Block;<br />
* How data usage strategies are applied to the data in the Data Block.<br />
* What type of data is eventually output from the Data Block and provided for future control use.<br />
<br />
Source code for the example can be found [http://research.engineering.wustl.edu/~boli/downloads/simple_example.zip here].<br />

<br />
[[File:Wcps_framework.png|600px|thumb|right|Figure 1. WCPS Architecture]] <br />
<br />
As shown in the right figure, WCPS simulates<br />
the feedback control loop of the control system as follows.<br />
Sensor data is generated from structural models. Through a cross-platform function call from Simulink, sensor data is injected to the<br />
corresponding wireless sensors in TOSSIM. Following the routes<br />
and transmission schedule calculated by the network manager module,<br />
TOSSIM simulates the end-to-end wireless communication of<br />
the sensor data packets from the sensors to the base station, and<br />
then return the packet delay and loss to the Interfacing Block in<br />
Simulink through the Python interface. The Packet Collector module<br />
then extracts packet delivery information(the delay and loss)from the message pool. Sensor<br />
data and their loss and delay are then provided to the Data Block,<br />
which then feed the sensor data to the controller at the right time<br />
based on the packet delay (if the packet is not lost). WCPS utilizes<br />
basic API (e.g., the dos, UNIX command) of MATLAB to<br />
do cross-platform function calls. In TOSSIM, we re-implement a<br />
printf method in TinyOS to send simulation results to the<br />
Interfacing Block.<br />
<br />
User inputs to WCPS includes excitation signals to the structure<br />
(e.g., acceleration caused by earthquakes) and wireless traces used<br />
as input to TOSSIM. Excitation signal of the structure is provided<br />
to the structure models in the format of MAT files.<br />
The scheduler module calculates transmission schedules. Networking<br />
schedule is then deployed into the MAC layer code of<br />
wireless nodes and becomes effective after a TinyOS compilation.<br />
The TDMA MAC layer in WCPS is developed based on the MAC<br />
Layer Architecture (MLA) library and further adapted for<br />
TOSSIM under TinyOS 2.1.1. Received Signal Strength Indication(<br />
RSSI) and wireless noises traces are collected from real-world<br />
environments and provided to the wireless model used by TOSSIM<br />
for realistic wireless network simulations.<br />
The interfaces between the Simulink model<br />
and TOSSIM are encapsulated as two MATLAB embedded functions<br />
in Simulink: the Interfacing Block and the Data Block. The<br />
Interfacing Block extracts delay and loss information from TOSSIM<br />
messages, and the Data Block decides what data will be used for<br />
discrete control during each sampling period. The federated architecture<br />
of WCPS provides great flexibilities to incorporate different<br />
structural models and implement alternative scheduling-control<br />
approaches.<br />
<br />
== WCPS Capabilities ==<br />
<br />
This section briefly reviews application of WCPS in extensive Wireless Structural Control studies, which shows capability of WCPS enabling<br />
in-depth tradeoff among sensing synchronization, wireless network delays, as well as reliability of the wireless network. Specifically for the wireless network presented in this section,<br />
wireless traces in TOSSIM were collected from a 5-sensor testbed located at Bryan Hall of Washington University, as in Fig. 2. All results presented here uses the TDMA MAC layer.<br />
[[File:Building_network.png|200px|thumb|left|Figure. 2. Wireless Network in A Building]]<br />
<br />
[[File:Wcps building prr statistics.png|300px|thumb|right|Figure. 3. Network Statistics]]<br />
Fig. 3 shows end-to-end network ratio changes with different re-transmission mechanisms in WCPS.<br />
Sensor 1 has the lowest delivery ratio because it has a 2-hop route to the base station. Since OTDC-1<br />
does not perform any retransmission, while OTDC-2 and OTDC-3<br />
performs retransmit each packet once and twice, respectively. Under<br />
OTDC-1 Sensors 1 and 4 have delivery ratios of 70% and over 95%, respectively. As expected more retransmissions improve the<br />
deliver ratios of all sensors at the cost of longer delays as described earlier. <br />
<br />
[[File:Control perf building 1.png|300px|thumb|right|Figure 4. Tradeoff Among Data Synchronization, Network Reliability and Network Delay. ]]<br />
<br />
Fig. 4 shows changes of required resource for building control. Underlying tradeoffs are: better sensing synchronization vs. larger delays (e.g., OTDC-1 vs. SC), and <br />
larger network delays trading for better reliability (e.g., OTDC-3, OTDC-2 vs. OTDC-1). In Fig.4(a), OTDC-k approaches consistently require<br />
less control power than SC. As k increases, OTDC-k requires slightly less control power. Similarly, as shown in Fig. 2(b), OTDC-1 reduces control force by 80% when compared to SC. The<br />
differences in control force among different OTDC-k approaches are negligible. The results that OTDC-1 outperforms SC in both<br />
metrics indicate resource requirements are more sensitive to data synchronization than to sensing delays in this building control system.<br />
OTDC-k with larger k results in negligible reduction of control power and force, indicating resource requirements are not sensitive<br />
to network reliability in this case study.<br />
<br />
Fig. 5 shows control performance regarding structural response. In term of peak inter-story drift in Fig. 5(a), OTDC-<br />
k achieves more reduction in inter-story drift than SC. Interestingly, higher k in OTDC-k increases peak inter-story drift. Recall a higher k leads to higher communication reliability but longer<br />
sensing delay. Inter-story drift is thus more sensitive to sensing delays than to data loss in this case study. Similarly, as shown in Fig. 5(b), OTDC-3 causes worse peak acceleration than all the<br />
other approaches. Hence, building structural responses are more sensitive to sensing delays than to data loss. In addition, OTDC-1 only slightly outperforms SC, which indicates limited impact of<br />
data synchronization on structural response.<br />
<br />
[[File:Control perf building 2.png|300px|thumb|right|Figure 5. Tradeoff Among Data Synchronization, Network Reliability and Network Delay.]]<br />
WCPS has efficiently integrated TOSSIM and Simulink. Fig. 2-4 shows that there exist complex tradeoffs among data synchronization, sensing<br />
delay, and network reliability under realistic wireless structural control settings. A realistic, integrated wireless control simulator like WCPS is critical in exploring these design tradeoffs<br />
in wireless control design. Our cyber-physical simulation methodology and scheduling-control co-design approaches presented here not<br />
only represent a promising step toward smart civil infrastructure, but also provide useful insights and tools that can be generalized<br />
to other cyber-physical systems employing wireless control.<br />

reusable components that implement MAC layer logic on top of them. The MLA architecture can be used to develop a large number of platform-independent <br />
MAC implementations, with little or no further effort required to adapt these implementations to new hardware platforms. Our current implementation of MLA<br />
is built on top of TinyOS 2.1.1. It currently supports platforms which use the CC2420 radio stack and has been tested on TelosB motes. In addition to providing<br />
interfaces and components for building new MAC layer implementations, MLA includes implementations of five representative MAC layers. Specifically for WCPS, we <br />
adopt and further change the pure-TDMA MAC protocol for centralized data communication. <br />

Wireless Cyber-Physical Simulator (WCPS) is an open-source simulation environment for wireless control systems. By integrating Simulink and the TOSSIM wireless sensor simulator in a holistic simulation environment, WCPS accurately captures the dynamics of both the physical systems and the wireless sensor-actuator networks used for control. WCPS has been used for [http://research.engineering.wustl.edu/~boli/papers/iccps13.pdf realistic case studies of wireless structural control systems for civil infrastructure]. The broad application of WCPS is to support cyber-physical systems research on large-scale wireless control systems through high-fidelity joint cyber and physical simulations. This site includes the code release, tutorial, and simulation examples for wireless structural control systems. WCPS is developed as part of [http://bridge.cse.wustl.edu the cyber-physical systems project on wireless structural health monitoring and control systems], a collaborative effort by Washington University, Purdue and UIUC. <br />

Wireless Cyber-Physical Simulator (WCPS) is an open-source simulation environment for wireless control systems. By integrating Simulink and the TOSSIM wireless sensor simulator in a holistic simulation environment, WCPS accurately captures the dynamics of both the physical systems and the wireless sensor-actuator networks used for control. WCPS has been used for [http://research.engineering.wustl.edu/~boli/papers/iccps13.pdf realistic case studies of wireless structural control systems for civil infrastructure]. The broad application of WCPS is to support cyber-physical systems research on large-scale wireless control systems through high-fidelity joint cyber and physical simulations. This site includes the code release, tutorial, and simulation examples for wireless structural control systems. WCPS is developed as part of [http://bridge.cse.wustl.edu the cyber-physical systems project on wireless structural health monitoring and control systems], a collaborative effort by Washington University, Purdue and UIUC. <br />

== WCPS Architecture ==<br />
<br />
[[File:Wcps_framework.png|600px|thumb|right|Figure 1. WCPS Architecture]] <br />
<br />
As shown in the right figure, WCPS simulates<br />
the feedback control loop of the control system as follows.<br />
Sensor data is generated from structural models. Through a cross-platform function call from Simulink, sensor data is injected to the<br />
corresponding wireless sensors in TOSSIM. Following the routes<br />
and transmission schedule calculated by the network manager module,<br />
TOSSIM simulates the end-to-end wireless communication of<br />
the sensor data packets from the sensors to the base station, and<br />
then return the packet delay and loss to the Interfacing Block in<br />
Simulink through the Python interface. The Packet Collector module<br />
then extracts packet delivery information(the delay and loss)from the message pool. Sensor<br />
data and their loss and delay are then provided to the Data Block,<br />
which then feed the sensor data to the controller at the right time<br />
based on the packet delay (if the packet is not lost). WCPS utilizes<br />
basic API (e.g., the dos, UNIX command) of MATLAB to<br />
do cross-platform function calls. In TOSSIM, we re-implement a<br />
printf method in TinyOS to send simulation results to the<br />
Interfacing Block.<br />
<br />
User inputs to WCPS includes excitation signals to the structure<br />
(e.g., acceleration caused by earthquakes) and wireless traces used<br />
as input to TOSSIM. Excitation signal of the structure is provided<br />
to the structure models in the format of MAT files.<br />
The scheduler module calculates transmission schedules. Networking<br />
schedule is then deployed into the MAC layer code of<br />
wireless nodes and becomes effective after a TinyOS compilation.<br />
The TDMA MAC layer in WCPS is developed based on the MAC<br />
Layer Architecture (MLA) library and further adapted for<br />
TOSSIM under TinyOS 2.1.1. Received Signal Strength Indication(<br />
RSSI) and wireless noises traces are collected from real-world<br />
environments and provided to the wireless model used by TOSSIM<br />
for realistic wireless network simulations.<br />
The interfaces between the Simulink model<br />
and TOSSIM are encapsulated as two MATLAB embedded functions<br />
in Simulink: the Interfacing Block and the Data Block. The<br />
Interfacing Block extracts delay and loss information from TOSSIM<br />
messages, and the Data Block decides what data will be used for<br />
discrete control during each sampling period. The federated architecture<br />
of WCPS provides great flexibilities to incorporate different<br />
structural models and implement alternative scheduling-control<br />
approaches.<br />
<br />
== WCPS Capabilities ==<br />
<br />
This section briefly reviews application of WCPS in extensive Wireless Structural Control studies, which shows capability of WCPS enabling<br />
in-depth tradeoff among sensing synchronization, wireless network delays, as well as reliability of the wireless network. Specifically for the wireless network presented in this section,<br />
wireless traces in TOSSIM were collected from a 5-sensor testbed located at Bryan Hall of Washington University, as in Fig. 2. All results presented here uses the TDMA MAC layer.<br />
[[File:Building_network.png|200px|thumb|left|Figure. 2. Wireless Network in A Building]]<br />
<br />
[[File:Wcps building prr statistics.png|300px|thumb|right|Figure. 3. Network Statistics]]<br />
Fig. 3 shows end-to-end network ratio changes with different re-transmission mechanisms in WCPS.<br />
Sensor 1 has the lowest delivery ratio because it has a 2-hop route to the base station. Since OTDC-1<br />
does not perform any retransmission, while OTDC-2 and OTDC-3<br />
performs retransmit each packet once and twice, respectively. Under<br />
OTDC-1 Sensors 1 and 4 have delivery ratios of 70% and over 95%, respectively. As expected more retransmissions improve the<br />
deliver ratios of all sensors at the cost of longer delays as described earlier. <br />
<br />
[[File:Control perf building 1.png|300px|thumb|right|Figure 4. Tradeoff Among Data Synchronization, Network Reliability and Network Delay. ]]<br />
<br />
Fig. 4 shows changes of required resource for building control. Underlying tradeoffs are: better sensing synchronization vs. larger delays (e.g., OTDC-1 vs. SC), and <br />
larger network delays trading for better reliability (e.g., OTDC-3, OTDC-2 vs. OTDC-1). In Fig.4(a), OTDC-k approaches consistently require<br />
less control power than SC. As k increases, OTDC-k requires slightly less control power. Similarly, as shown in Fig. 2(b), OTDC-1 reduces control force by 80% when compared to SC. The<br />
differences in control force among different OTDC-k approaches are negligible. The results that OTDC-1 outperforms SC in both<br />
metrics indicate resource requirements are more sensitive to data synchronization than to sensing delays in this building control system.<br />
OTDC-k with larger k results in negligible reduction of control power and force, indicating resource requirements are not sensitive<br />
to network reliability in this case study.<br />
<br />
Fig. 5 shows control performance regarding structural response. In term of peak inter-story drift in Fig. 5(a), OTDC-<br />
k achieves more reduction in inter-story drift than SC. Interestingly, higher k in OTDC-k increases peak inter-story drift. Recall a higher k leads to higher communication reliability but longer<br />
sensing delay. Inter-story drift is thus more sensitive to sensing delays than to data loss in this case study. Similarly, as shown in Fig. 5(b), OTDC-3 causes worse peak acceleration than all the<br />
other approaches. Hence, building structural responses are more sensitive to sensing delays than to data loss. In addition, OTDC-1 only slightly outperforms SC, which indicates limited impact of<br />
data synchronization on structural response.<br />
<br />
[[File:Control perf building 2.png|300px|thumb|right|Figure 5. Tradeoff Among Data Synchronization, Network Reliability and Network Delay.]]<br />
WCPS has efficiently integrated TOSSIM and Simulink. Fig. 2-4 shows that there exist complex tradeoffs among data synchronization, sensing<br />
delay, and network reliability under realistic wireless structural control settings. A realistic, integrated wireless control simulator like WCPS is critical in exploring these design tradeoffs<br />
in wireless control design. Our cyber-physical simulation methodology and scheduling-control co-design approaches presented here not<br />
only represent a promising step toward smart civil infrastructure, but also provide useful insights and tools that can be generalized<br />
to other cyber-physical systems employing wireless control.<br />
<br />
==Environment Installation==<br />
* Install TinyOS<br />
<br />
<pre><br />
WCPS is implemented and tested on MacOS X (snowleopard), Windows XP, and Windows 7. Current release of WCPS is under TinyOS 2.1.1, which can be installed following the two methods.<br />
</pre><br />
* Follow the TinyOS official tutorial on installation of TinyOS for your specific platform: [http://docs.tinyos.net/tinywiki/index.php/Getting_started#User_Contributed_Methods Link]<br />
* Directly download the pre-tested TinyOS 2.1.1 image from here: [http://research.engineering.wustl.edu/~boli/downloads/tinyos-2.1.1.dmg TinyOS2.1.1 for SnowLeopard(and possibly later versions)] [Cygwin package coming soon.]<br />
<br />
* Install Mac Layer Architecture(MLA)<br />
<pre><br />
The MAC Layer Architecture (MLA) provides a component-based architecture for MAC protocols in wireless sensor networks. MLA extends the Unified Power <br />
Management Architecture to provide the hardware-independent interfaces required by timing sensitive MAC protocols, and defines platform-independent <br />
reusable components that implement MAC layer logic on top of them. The MLA architecture can be used to develop a large number of platform-independent <br />
MAC implementations, with little or no further effort required to adapt these implementations to new hardware platforms. Our current implementation of MLA<br />
is built on top of TinyOS 2.1.1. It currently supports platforms which use the CC2420 radio stack and has been tested on TelosB motes. In addition to providing<br />
interfaces and components for building new MAC layer implementations, MLA includes implementations of five representative MAC layers. Specifically for WCPS, we <br />
adopt and further change the pure-TDMA MAC protocol for centralized data communication. <br />
</pre><br />
<br />
* Follow the instructions here: [http://wsn.cse.wustl.edu/index.php?title=MAC_Layer_Architecture Install MLA].<br />
<br />
* Install MATLAB and Simulink<br />
* If you already have MATLAB MATLAB 7.11.0.584 (2010b) or later version, skip this step. Otherwise, follow the tutorial here: [http://www.mathworks.com/help/install/index.html install MATLAB]<br />
<br />
* Install Python<br />
If you already have Python 2.7.2 or later version installed, skip this step. Otherwise, follow the manual here: [http://www.python.org/getit/ install Python]<br />
<br />
== Download WCPS ==<br />
* [http://research.engineering.wustl.edu/~boli/downloads/cygwin.zip A complete package of Cygwin with TinyOS 2.1.1, MLA, TOSSIM pre-installed] with a [http://research.engineering.wustl.edu/~boli/downloads/WCPS_Cygwin_Installation_Usage_Tutorial.txt WCPS Cygwin Installation & Usage Tutorial]<br />

<br />
== Use WCPS ==<br />
<br />
Wireless network plays a critical role in close-loop wireless control system. Sitting on top of WCPS, simulating <br />
a wireless TDMA network is as easy as collecting these NesC files below:<br />
<br />
* "Makefile" takes advantage of the fact that it's not necessary to recompile all the files not changed while specifying all necessary libraries.<br />
* "TestNetwork.h" defines necessary message structures for the wireless communication.<br />
* "TestNetworkAppC.nc" connects claimed application interfaces to interfaces that are defined in the hardware library.<br />
* "TestNetworkC.nc" implements send/receive functionality of a wireless node.<br />
* "tossim-call.py" configures TOSSIM network and does packet injection into the Tossim network.[http://research.engineering.wustl.edu/~boli/downloads/TinyosFiles.zip All above necessary files.].<br />
* Re-implemented TOSSIM libraries for TDMA simulation.[http://research.engineering.wustl.edu/~boli/downloads/pure-tdma.zip TDMA components for TOSSIM.].<br />
* Wireless traces: [http://research.engineering.wustl.edu/~boli/downloads/building_noise_n_rssi.zip Traces for 5-sensor wireless network in a building].<br />
<br />
Put all the above files into the same folder, prompt a terminal (or a Cygwin window), and in the terminal run <br />
<pre><br />
Make micaz sim<br />
</pre><br />
<br />
If TinyOS and python is configured correctly, go ahead and run in the terminal:<br />
<pre><br />
./tossim-call.py<br />
</pre><br />
<br />
Having collected aforementioned TinyOS files, a simplified example that uses key networking Interfacing Block and Data Block of WCPS is shown in Fig. 6.<br />
[[File:Simple_wcps_example.png|500px|thumb|center|Figure 6. A Simple Example that uses Interfacing and Data Block of WCPS. ]]<br />
<br />
This examples shows:<br />
<br />
* How input data in Simulink is injected to TOSSIM network; <br />
* How TOSSIM Interfacing Block runs as a Matlab Embedded function; <br />
* What type of data is output from the Interfacing Block;<br />
* How data usage strategies are applied to the data in the Data Block.<br />
* What type of data is eventually output from the Data Block and provided for future control use.<br />
