Abstract
Energy efficiency is a measure of the performance of IEEE 802. 11 wireless multihop mobile ad-hoc networks. The operating life of the battery can be increased by controlling the contention window size at a node. A new backoff algorithm based on a dynamic adaptation of its maximal limit is proposed. This is a function of the number of nodes in the network and their mobility. In this algorithm, node's percentage of residual energy is also considered. The loss of packets due to the collisions in the MAC layer and mobility is reduced. Thereby the transport protocol performance can be improved. Our extensive ns-2-based simulation results have shown that the proposed scheme provides better performance in terms of energy goodput, throughput, packet delivery ratio, as well as the end-to-end delay.
