End-user's Tutorial on using WCPS: The Wireless Cyber-Physical Simulator
WCPS is design for, but not limited to, realistic Wireless Structural Control simulations. The layered infrastructure and efficient integration of state-of-the-art control and wireless networking tools, i.e., Simulink and TOSSIM, have made WCPS an ideal choice for general wireless control simulations with Simulink and TOSSIM.
The following tutorial introduces how to configure general MATLAB, TinyOS, and PYTHON environments, as well as the WCPS framework. The tutorial herein is specifically organized for end-users who do not do much development but instead trying to do wireless control simulations with Simulink and TOSSIM.

Software Environment Setup
Install TinyOS
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 three methods.
- (1) Follow the TinyOS official tutorial on installation of TinyOS for your specific platform: Link
- (2) Directly download the pre-tested TinyOS 2.1.1 image from here: [under construction Cygwin] [under construction Mac OS X]
Install Mac Layer Architecture(MLA)
Follow the instructions here: Install MLA.
Install MATLAB and Simulink
If you already have MATLAB MATLAB 7.11.0.584 (2010b) or later version, skip this step. Otherwise, follow the tutorial here: install MATLAB
Install Python
If you already have Python 2.7.2 or later version installed, skip this step. Otherwise, follow the manual here: install Python
Environment Setup Testing
To test if TinyOS, Python and WCPS were configured correctly, pleas read ahead and do the following example.
Building a 5-node Network in TOSSIM
Makefile
"Makefile" takes advantage of the fact that it's not necessary to recompile all the project files that has not been changed. To have the "Makefile" for our project, copy the code below into a txt file and save as "Makefile" without any suffix.
TestNetwork.h
"TestNetwork.h" defines necessary message structures for the wireless communication. Copy the code below into a txt file and save as "TestNetwork.h".
TestNetworkAppC.nc
"TestNetworkAppC.nc" connects claimed application interfaces to interfaces that are defined in the hardware librare. Copy the code below into a txt file and save as "TestNetworkAppC.nc".
TestNetworkC.nc
"TestNetworkC.nc" Implements send/receive functionality of a wireless node. Copy the code below into a txt file and save as "TestNetworkC.nc".
tossim-call.py
"tossim-call.py" configures TOSSIM network and does packet injection into the Tossim network. Copy the code below into a txt file and save as "tossim-call.py".
=== Make ===
Put all the above files into the same folder, prompt a terminal (or a Cygwin window), and: 1. In the terminal, Make micaz sim and hit return 2. In the terminal ./tossim-call.py
Wireless traces
To run the network simulation above, we need wireless RSSI (strength of the wireless communication signal) and wireless Noise for Tossim to build Signal to Noise Ratio (SNR) model. Two options to do are:
1) Use the provided RSSI and noise traces for test purposes.
2) Use the code [rssi.zip] to collect the RSSI values and use code [noise.zip] to collect the wireless noise traces.
Test run
And you are ready to go for the wireless network setup.
