Smart Outlet Network for Energy-Aware Services Utilizing Various Sensor Information

This paper describes the construction of a smart outlet network as a system for automated energy-aware services utilizing various sensor information. With high-granularity sensing of power consumption of each electrical appliance in home, and with environmental (humidity, temperature, light) sensors and a motion sensor installed on the smart outlets, the appliances are under policy-based automatic control. The authors have deployed the system in real-life environments, and have implemented the following functions and power management policies, 1) visualization of power consumption data of appliances for enhancing energy-awareness, 2) policy-based power control utilizing various sensor information collected at the smart outlets, 3) automatic coordination of multiple or different appliances in both centralized and distributed manners.
