WirelessHART is an open
 
wireless sensor-actuator network standard for industrial
 
process monitoring and control that requires real-time data
 
communication between sensor and actuator devices. The
 
standard has been instrumental in the adoption and
 
deployment of wireless network technology in the field of
 
process monitoring and control. Salient features of a
 
WirelessHART network include a centralized network

and redundant routes. The unique characteristics of
 
WirelessHART introduce unique challenges for real-time
 
transmission scheduling.

Wireless control networks represent a new generation of communication technology for industrial process monitoring and control. With the adoption of WirelessHART, an open wireless sensor-actuator network standard, recent years have seen successful real-world deployment of wireless control in process industries. Industrial control systems impose stringent real-time and reliability requirements on wireless control networks. We are developing a new theory and protocols for real-time wireless control networks. Our research addresses both practical problems in current WirelessHART networks and fundamental challenges faced by future wireless control networks.
