Smart Adaptable Indoor Lighting System (SAILS)

The issue of saving energy is the main incentive in many researches. Lighting is the main factor contributing to these problems is lighting. Its costs to be covered by local municipality are heavy. The aim of this work is to propose a smart adaptable lighting system. In particular, we proposed an approach that generates in an intelligent way all possible lighting strategies according to user preferences while respecting lighting norms. Moreover, our automated system control light level to save energy. It dims lighting sources to maintain a required level when needed according to space occupation and light intensity level. Moreover, it detects nodes failure and overcomes resulting lack. Our system implements energy efficient technologies as ZigBee and LEDs. It monitors sensors and lighting sources states in real-time. To assess the usefulness of our system, we compared our system to other works. Experimental results show that it saves remarkable power, which can reach 77%, as compared to conventional systems without sensors and without an intelligent system.
