Abstract ” In other to save energy, several countries recently made laws related to standby power consumption. To success this exertion, we should consider not only power reduction of consumer electronics itself but also efficient automatic control in networked home environment. In this paper, we present a design approach and implementation result of control mechanism for standby power reduction. Proposed mechanism has the Host-Agent based structure and uses the IEEE 802.15.4 based ZigBee protocol for communication and security between Host and Agents. We verified reliability of proposed mechanism and reduction effect of standby power; also, we applied implemented device to scenario which is similar to user living pattern. Experimental results demonstrate that in the proposed mechanism, standby power consumption of Agent which is connected to consumer electronics can be reduced by 203mW

I. INTRODUCTION
Standby electricity is the energy consumed by appliances when they are not performing their main functions or when they are switched off. As more and more appliances are being used in households and offices, their energy consumption during standby periods represent a significant share of the total energy used. Household appliances and office equipments such as televisions (TVs), video recorders, audio players, telephone answering and facsimile machines, computers, printers and copiers contribute to this standby loss which is relatively low, with typical loss per appliance ranging from less than 1W to as much as 25W. According to the IEA (International Energy Agency), on an average, 10% of a total household (OECD) power consumption is being wasted in the form of standby power. Moreover, due to the special characteristics of home network devices such as set top box, xDSL modem, home gateway, PC and TV can all be connected to the external communication system in standby mode; an increase of standby power consumption is expected.
