分簇式路由协议LEACH随机地将节点设置成首领节点均衡整个网络的能量消耗.提出一种簇头选择优化的方法,将簇首选择能耗计算到网络的整个能耗中,推导出最优簇首数,然后利用距离关系将所有节点群组化,使群组的数量与期望最优簇头个数相同,簇首的实际个数与期望的簇头个数相同,从而提高了网络生命周期,节省了网络能耗.

LEACH is a typical level routing protocols which randomly set the clusterhead to balance energy consumption of the whole network.This paper presented a cluster head selection optimization method.Firstly,the energy consumption of the cluster head selection was calculated in the entire network,from which the optimal cluster head derived.Secondly,all nodes were grouped by distance relationship,ensuring that the number of group was equal to the expected number of the optimal cluster head,and the actual number cluster head was equal to the expected number of cluster head,which increased the network life and saved energy consumption of the network.
