首发时间:2011-06-01
摘要:本文在全面分析LEACH算法的基础上,通过对LEACH算法中随机簇头选择方法、簇形成阶段以及簇头传输数据方式的改进,提出了一种新的算法--基于权值的无线传感器网络簇内多跳传输算法(LEACH-N算法)。最后用MATLAB对改进后的算法进行了仿真。仿真结果表明,LEACH-N算法均衡了节点的能耗,有效地延长了整个网络的生存时间。

Cluster Formation With Multi-hop Transimission Based on Weighted Clustering Algorithm in WSN
Abstract:This paper entirely analyzes LEACH routing protocols, and modify LEACH's stochastic clusterhead selection algorithm、the cluster formation phase and the transmission way of cluster head.Then we present a new agreement An Cluster Formation With Multihop Transimission Based on Weighted Clustering Algorithim in WSN. Finally, we use MATLAB to simulate the algorithm.The simulation result shows that the protocol improved the energy balance of a node, effectively and extended the survival time of the entire network.
Keywords: WSN LEACH Cluster-Head Cluster Formation
