Design and implementation of an energy-efficient lighting system driven by wireless sensor networks

A wireless sensor network is a technology that aims to collect real world information by wireless communication which connects many computer to network, and it is expected its practical realization. On the other hand, research on the office environment also has attracted a great deal of attention in recent years. It has been reported that light environment affects the productivity of user. In this paper, we propose wireless sensor network-driven intelligent lighting system (WSN-ILS below). WSN-ILS provides a light environment to each user by innetwork processing in wireless sensor network. WSN-ILS achieves energy-efficient light environment by performing an individual control to each lighting from sensor node. WSN-ILS has two schemes to control lighting from the sensor node. We will examine effectiveness of the WSN-ILS on an existing equipment.
