WSAN QoS Driven Control Model for Building Operations

Currently wireless based control systems lack appropriate development methodologies and tools, indeed the control model and its underlying wireless network are developed separately which often lead to unstable and suboptimal implementations. In this paper we introduce a hybrid-based design methodology that considers Wireless Sensors and Actuators Network (WSAN) performance parameters in order to develop an optimized control system tailored to the specific application environment and sensor network conditions. We first identify the boundaries of the control parameters that maintain stable and optimal control model. Within these boundaries, we determine the optimal WSAN Quality of Service (QoS) parameters through a tuning process in order to reach to optimal Control/WSAN design as illustrated in the case study. The methodology has been illustrated through a distributed lighting control developed using our hybrid/multi-agent platform.
