基于能量异构的无线传感器网络的分簇算法研究

分簇路由算法是无线传感器网络中减少能量消耗的关键技术之一，因而成为目前国际上的研究重点。考虑到大多数分簇算法都是在同构网络中提出的，对异构网络的适应性差，本文提出一种新的异构网络分簇算法，该算法采用ECS网络结构，在选举簇头时将节点刺余能量和与所在簇的质心间的距离结合起来考虑。仿真结果表明算法在延长网络生存时间上比LEACH和基于ECS结构的分簇算法有很大的提高。

Research on Unequal Energy- based Clustering Algorithm for Wireless Sensor Networks

Cluster-based routing protocols is a kind of key technique used to reduce energy consumption in wireless sensor networks,so it becomes a hotspot in international research.obtained in homogeneous networks,most of Clustering Algorithm isn' t adapt the heterogeneous network..This paper proposed a new clustering algorithm,which uses ECS network structure.We combine nodes' remaining energy with the distance between nodes to the centroid of the cluster in the process of cluster heads elec- tion.The simulation result shows that the algorithm in this paper is much better than LEACH and ECS-based clustering algo- rithm in prolonging the network lifetime.
