Energy-Efficient Routing Protocol Based on Probability of Wireless Sensor Network

摘要

This chapter mainly discusses the problem of wireless sensor network routing protocols. Based on analysis of the disadvantages of information implosion and overlapping caused from implementation mechanisms of the flooding protocol, energy-efficient routing protocol based on probability of wireless sensor network (ERPBP) is proposed and evaluated. It uses the node distance and residual energy as the weights to calculate the forwarding probability of neighbor nodes and chooses some of maximum forwarding probability nodes as router. It saves the energy by avoiding redundancy packet copies produced and improves the disadvantage of flooding routing protocol. Performance analysis and simulation experiment show that the new protocol effectively reduces the data redundancy, reduces the energy consumption, and prolongs the network lifetime.
