The inadequacy of the classical media access protocols for considering the transmitter power as the critical resource and a tunable parameter for increasing the throughput, conserving the battery power, and providing the quality of service for the communication has given a new perception for the power controlled media access protocols in ad hoc networks. Former researchers have proposed some modifications of IEEE 802.11 with power control, but most of these protocols degrade network throughput. A novel power controlled MAC protocol based on SNR in mobile Ad hoc networks is presented in this paper. Simulation results demonstrate that compared to the IEEE 802.11 MAC protocol, the proposed protocol can decrease the power consumption greatly, and improve the energy utilization of mobile terminals while maintaining the throughput performance.
