Abstract : In recent years, Information and Communications Technology (ICT) has totally changed the people daily life in the Digital Home. Meanwhile, not only the amount of CO2 emission of ICT, so called ''footprint'', is increasing without cease, but also the price of electricity is constantly rising. Thus, it is quite important to reduce energy consumption in the home network and home devices for the environmental and economic reasons. In order to cope with this context, the thesis concerns the design, the evaluation, and the implementation of a novel set of mechanisms with the purpose of responding to home network energy consumption problems. We proposed firstly an Overlay Energy Control Network which is formed by the overlay energy control nodes. Each node is connected to one device which forms an overlay control network to coordinate the power states of the device. Then, a testbed for HOme Power Efficiency system (HOPE) is implemented to demonstrate the technical solution for energy control in a real home network environment with several frequently used scenarios. After analyzing user's way of use of their home network equipment, we propose a power management which controls the devices based on the analysis of the collaborative services. These frequently used collaborative services require different functional blocks in different devices. This model provides the possibility to turn on the right requested functional blocks in the right device at the right moment. Finally, based on the former contribution, the collaborative overlay power management offers several possible tradeoffs between the power consumption and the waiting delay in the home network.
