本文首先分析WSN中的LEACH协议,然后针对LEACH协议存在的不足,提出改进算法,在改进算法中将能量作为当选簇头节点的一个参数,每轮选举中选择能量相对较高的节点作为簇头节点,综合考虑了节点能量和阀值大小对簇头选举的影响,最后通过仿真,表明该算法更具健壮性,同时均衡系统能量消耗,延长网络生命周期。
This paper first analyzes the LEACH protocol in WSN, and then proposes the improved algorithm in view of the deficiency of the LEACH protocol. In the improved algorithm, energy is taken as a parameter of the elected cluster head node. In each round of election, the node with the higher energy is selected as the cluster head Node, the effect of node energy and threshold size on cluster head election is considered. Finally, the simulation shows that the algorithm is more robust and balances the system energy consumption and prolongs the network life cycle.
