基于WSAN的协同灯光控制系统

Wireless sensor and actuator network (WSAN) is a new generation of wireless sensor network (WSN) and has been widely used in various applications. WSANs are not only able to monitor physical environment, but also to change the environment by appropriate action. In this paper, with respect to a typical WSAN application:light control, we present a collaborative light control system for intelligent lighting control based on an illuminance distribution model . The system focuses on meeting human illuminance and human uniformity requirements as far as possible simultaneously. To reach the goal, a collaborative control method is used. For calculating the control signals, a simple yet efficient gradient descent algorithm is applied. Simulation is presented to verify the effectiveness of our design and a prototype is also constructed for a further practical research.
