Networked Power Management for Home Multimedia

The digitalization of home multimedia brings with it increased numbers of different kind of new devices. Although adding new user experiences, this will significantly increase energy consumption at home and globally. In this article we present one potential solution to enable more aggressive power management in networked home devices. This solution is based on UPnP Low power which allows devices in power save modes to be discovered and waken up. It is also shown based on implemented prototype that efficient power management system can be built on top of UPnP low power, particularly if home router manufacturers support the UPnP low power proxy service in their devices.
