This manuscript introduces, implements and evaluates a feedback-based adaptation mechanism that adjusts the transmission power of a wireless card on commodity mobile devices. Main focus of this work is to minimize the power consumption by adjusting the transmission power of the wireless card, thus extending the battery life, while negative effects on connection quality are avoided. To achieve that, a mechanism that optimizes the power depending on the quality of the connection is presented…

Interference Analysis and Transmit Power Control in IEEE 802.11a/h Wireless LANs
Simulation results show MiSer's clear superiority to other two-way or four-way frame exchange mechanisms in terms of energy conservation, and the key idea of MiSer is to combine TPC with PHY rate adaptation and compute offline an optimal rate-power combination table.

The initial simulation results show that the PCMA can improve the throughput performance of the non-power controlled IEEE 802.11 by a factor of 2 with potential for additional scalability as source-destination pairs become more localized, thus providing a compelling reason for migrating to a new power controlled multiple access wireless MAC protocol standard.
