Wireless sensor and actuator networks (WSANs) combine a large number of sensor nodes and a lower number of actuator nodes that are connected with wireless medium, providing distributed sensing and executing appropriate tasks to the events monitored in a special region of interest. The design of coordination mechanisms among nodes is considered in this paper. First, we formulate the mathematical models for WSANs system. Then, a strategy is proposed to assign proper tasks to actuators based on the characteristics of current events. Finally, according to system requirements, a distributed PID neural network control scheme is adopted to take coordinated actions of actuators on the given tasks. The simulations demonstrate the effectiveness of our proposed methods.
