An Adaptive Energy Efficient MAC Protocol for Wireless Ad Hoc Networks

Several transmit power control MAC protocols have been designed primarily to reduce the energy consumption in wireless ad hoc networks. On the other hand, many adaptive rate MAC protocols have been mainly proposed to improve the network throughput. In this paper, we proposed a new energy efficient MAC protocol for the distributed coordination function (DCF) IEEE 802.11 b based ad hoc networks which also maximize the overall network throughput. This protocol is known as traffic sensing adaptive rate power (TSRP) control MAC protocol. The basic idea of the TSRP protocol is that, rather than just matching the channel condition, the sender sense outgoing traffic based on the traffic load and the queue condition. Then the MAC layer chooses the energy efficient rate-power combination that is suitable to deliver all the packets comes from upper layer or schedule the transmission of the packets waiting in its queue with minimum delay. Our analytical and simulation results show that, TSRP protocol can provide more energy saving and at the same time can achieve maximum throughput.
