Wireless Sensor-Actuator Networks (WSANs) represent a new generation of communication technology for industrial process control. A feedback control system in process industries (e.g., oil refineries) is implemented in a WSAN for process monitoring and control applications (Figure 2). Networked control loops impose stringent reliability and real-time requirements for communication between sensors and actuators. With the adoption of WirelessHART, recent years have seen successful real-world deployment of WSANs for process monitoring and control. As they continue to evolve in process industries, real-time transmission scheduling issues are becoming increasingly important for WirelessHART networks.
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 management architecture, multi-channel TDMA transmission, and redundant routes. The unique characteristics of WirelessHART introduce unique challenges for real-time transmission scheduling.
