A street lamp clustered-control system based on wireless sensor and actuator networks

In order to resolve the problems of city street lamp control and management, a street lamp clustered-control system based on wireless sensor and network (WSANs) is proposed in this paper. In the system, the related information of vehicles running on the road will be detected by the sensors deploying along the both side of the road, and then the sensing data will be passed to the actuators being equipped on the lamps through multi-hop wireless communication. The actuators gather the information from the sensors and regulate the brightness of the lamp by the distributed and cooperated control algorithm. According the security rulers of driving a vehicle, a certain number of lamps in a security distance before and after the vehicle will be turned on. The street lamp clustered-control system is good at energy saving and validated by the experiment results.
