Micro power management of active 802.11 network interfaces
Master of Science
Micro power management (muPM), a standard-compliant MAC level solution to save power for active 802.11 interfaces is developed. muPM enables an 802.11 interface to enter unreachable power-saving modes even between MAC frames, without noticeable impact on the traffic flow. To control data loss, muPM leverages the retransmission mechanism in 802.11 and controls frame delay to adapt to demanded network throughput with minimal cooperation from the access point. Extensive simulation has been conducted to systematically investigate an effective and efficient implementation of muPM. A prototype muPM on an open-access wireless hardware platform has been presented. Measurements show that more than 30% power reduction for the wireless transceiver can be achieved with muPM for various applications without perceptible quality degradation.
