An Novel Energy Balanced Dynamic Routing Protocol Based on Probability in Wireless Sensor Netwoks
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. The authors introduce the typical energy model to compute energy consumption and state conversion to reduce energy consumption. In addition, they 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.
