Abstract

Energy limitation is a critical issue in wireless ad hoc networks. Researchers have developed some power-aware mechanisms in routing area to prolong the lifetime of connections in networks. The existed power-aware routing protocols often use residual energy, transmission power, or link distance as the metrics to select an optimal path. The investigation in this paper indicates that these route selections will cause rapid energy exhaustion in parts of the network, thus degrade the survivability of whole network. To average the energy consumption over the network with higher energy efficiency, a novel route selection mechanism, based on novel metrics, the relay capacity and the relay efficiency, is proposed. Simulation results show that this method saves energy with significantly more robust connectivity.
