WSAN-based energy efficient system in building: A monitoring and scheduling

In response to environmental issues about energy saving and reducing CO2 emissions, energy consumption monitoring is desirable particularly in office or school premise. In this paper, we propose a system to monitor and control electrical devices in a building. The system consists of pervasive layer, controller, and application layer. Wireless Sensor Network is utilized to actuate the appliances and sense the electricity usage. The system was deployed and analyzed in a University's test-bed. To measure the system performance, comparison between with and without scheduling state of electrical devices is performed. The result shows energy efficiency of 41.79%.
