Summary:We propose a number of techniques to reduce energy consumption for mobile computers. We use extra dedicated low power modules to cut processor cycles of the main CPU, i.e., hardware and software decomposition. These modules are autonomous and can be powered down individually. Furthermore, as networking consumes a large part of a mobile system's battery resources, much effort is put into reducing energy consumption in this part. We use intelligent network interfaces with a power aware network protocol, and a MAC protocol that minimizes the 'on-time' of network interfaces to reduce energy. There is a direct link between QoS and energy consumption. Therefore we move power management into the QoS domain.
