An Novel Energy Balanced Dynamic Routing Protocol Based on Probability in Wireless Sensor Netwoks

Abstract

Nodes in most wireless sensor networks (WSNs) are powered by batteries with limited energy. So it requires energy efficiency techniques to increase the lifetime of the network.In this paper, an novel energy balanced dynamic routing protocol based on probability(EBDRP-P) is proposed,which is able to prolong network lifetime and balance energy consumption between cluster heads. We introduce the typical energy model to compute energy consumption and state conversion to reduce energy consumption. In addition,we use residual energy,distance and neighbor cluster head number to compute probability of a head becomes the next hop,then reference the ideas of minimum cost spanning routing tree to constructure dynamic routing,namely,always select the maximum probability head as the next hop,which can balance the energy consumption between cluster heads and to prolong network lifetime.Further, simulation experiments are conducted to compare the EBDRP-P with some wellknown clustering algorithms and simulation results show that the proposed methods overcomes the existing methods in the aspects of energy consumption and network lifetime in wireless sensor networks.
