Balance-Aware Energy-Efficient Geographic Routing for Wireless Sensor Networks

Geographic routing is an attractive localized routing scheme for wireless sensor networks (WSNs). Most WSNs are consisted of nodes which are all limited in power, so how to employ a proper routing protocol to save energy consumption is a hot topic for research. In this paper, a balance-aware energy-efficient geographic routing protocol BEGR is proposed. Both energy consumption in communication and residual energy at nodes are considered in BEGR. We prove that our protocol is loop-free and can adapt to dynamic scenarios. Simulation results demonstrate that BEGR is better than other protocols in prolonging network lifetime greatly based on first-dead time.
