大规模无线传感网络的混合LEACH协议研究
Research on Hybrid LEACH Protocol for Large Scale Wireless Sensor Networks
摘要
Abstract
In large scale wireless sensor networks,how to reduce energy consumption is the most important techni⁃cal challenge. Therefore,the design of energy-efficient routing protocol has become a hot research topic. In order to reduce the energy consumption of sensor nodes,based on the LEACH algorithm,this paper proposes a hybrid wire⁃less sensor network energy saving routing algorithm which is suitable for large scale wireless sensor networks. First⁃ly,according to distance information,a routing algorithm was designed,in which a cluster member can transmit data to the base station via cluster head or can directly transmit data to the base station. Then the condition that the meth⁃od must satisfy is derived from the energy consumption. Simulation results obtained by MATLAB show that,com⁃pared with the existing LEACH protocol and M-LEACH protocol,the hybrid routing protocol can effectively im⁃prove the life of the nodes around the base station,and thus prolong the lifetime of the whole network.关键词
