Abstract

Energy limitation has become a performance bottleneck for mobile ad hoc networks. IEEE 802.11 has been adopted as the current standard MAC protocol for ad hoc networks. However, it has not the ability of adjusting power level dynamically, that reduces the performance of network. 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.
