摘要
针对LEACH协议生成非均匀的簇造成能量损耗的问题,以降低能量损耗为研究目的,结合PEGASIS协议的特点,从选择簇首节点、形成簇、簇间路由等方面对LEACH协议进行了改进。经过理论分析和仿真实验,对该协议的性能进行测试,并使用对比的方法,与LEACH协议进行比较。仿真实验结果表明,该路由协议的设计使各节点较均衡地消耗能量,节点生存时间更长,延长了整个无线传感器网络的生命周期。
Aimed at the problem of energy loss result from nonuniform cluster generated by LEACH protocol, to reduce the energy loss for research purposes, combined with PEGASIS protocol, the first LEACH protocol is improved from the cluster, cluster formation, cluster routing. Through theoretical analysis and simulation experiments to test the performance of this proto- col, and use the contrast method, and compared with the LEACH protocol. Simulation results show that the protocol enables each node in the network more balanced energy consumption, nodes survive longer, thus extending the life cycle of wireless sen sor networks.
