Energy efficient street lighting control system using wireless sensor networks

The Street lighting systems is one of the greedy consumers of electricity. It represents a financial burden on local authority. Reducing its cost is the purpose of many research projects.The idea presented in this paper, is the development of a street lighting control system based on wireless sensor networks to reduce the power consumption.Our new method is around a control system, where the Street lighting functionality is proportional to the density of traffic. A wireless sensor node composed of a distance-measuring sensor, used as a traffic detector,a control unit and a radio transmitter are installed in every lamppost along the road. This set of nodes forms a wireless network configured as one-dimensional wireless network to control the street lighting.
