摘要

针对LEACH分簇路由协议存在的簇头数目和分布位置不合理等问题导致能耗不均衡、网络周期不理想

提出了一种基于能量和距离加权的簇头选择优化算法。通过加入节点到基站的距离和节点剩余能量作为簇头选取的参考因素

依据改进后的阈值公式使得选取的簇头数达到预设最优值

并通过簇头的二次选择

最终确定最佳的簇头。仿真结果表明:相比于LEACH协议

该算法可以有效地延长网络生命周期

使网络能耗更加均衡。

Abstract

Aiming at problems of unbalanced energy consumption and unideal network lifetime

caused by cluster head number and unreasonable distribution location of LEACH clustering routing protocols

a cluster head selection optimal algorithm is proposed based on energy and distance weighted. Considering distance from node to base station and residual energy of nodes as reference factors of cluster head selection

according to improved threshold formula

make the number of selected cluster head reach preset optimal value

and the optimal cluster head is confirmed by reselection of the cluster head. Simulation result shows compared with LEACH protocol

the proposed algorithm can effectively prolong lifetime of network and network energy consumption is more balanced.
