| 摘 要： | 针对无线传感器网络（WSN）中分簇路由协议LEACH算法中簇首分配不均以及簇首与Sink节点直接通信问题进行研究．提出一种基于LEACH成簇思想的分簇路由协议。该算法基于节点剩余能耗和已担任簇首时间选举簇头。簇头间采用贪婪算法形成一条链，在该链中又选出一个簇头，将整个网络的数据融合后转发给基站。MatLab仿真结果显示，改进后的算法在均衡网络节点能耗和网络的生存时间上比LEACH算法有很大提高。

| Abstract: | Studies the uneven distribution of cluster head and to communicate directly with sink of clus- tering algorithm LEACH routing protocol in WSN, and proposes a sub-cluster routing protocol based on the method of LEACH. This algorithm selects the head of the cluster on the basic of the node residual energy and served cluster time. The heads of the cluster uses greedy algo- rithm to make a chain, and selects another head in this chain, and then the data of the whole network forwards to the base station after amalgamation. The MatLab simulation shows that the protocol improved can balance the node＇s energy consume and the lifetime of network, and it has been greatly improved compared with LEACH. |
