无线传感器网络权值分簇路由协议改进

无线传感器网络是一种无线自组织网络,它由大量能量有限的传感器节点组成。怎样节省能量,高效利用能量,能量负载平衡是延长无线传感器网络服务寿命的重要技术。该文首先分析了典型的无线传感器网络路由协议,随后提出在GSEN协议基础上,利用权值分簇算法改进簇首,从而得到一个全新的高效的分簇路由协议。用MATLAB对LEACH,GSEN,以及改进后的GSEN进行仿真,模拟仿真结果显示,该方案能更好地提高网络寿命。

An Improvement Routing Protocol by Weighted Clustering Algorithm in WSN

The wireless sensor networks（WSN） is a type of the wireless ad - hoc networks. It is composed of nodes with limited battery power. Energy saving, energy efficiency, energy balance are important technologies to prolong service life of WSN. In this paper, we first entirely analyzes LEACH protocol and GSEN protocol, then present a novel clustering muting protocol based GSEN, which elects clusters by using weighted clustering algorithm. At last, simulations are given for the protocol proposed with MATLAB. Simulation results show that this protocol can reduce overall energy.
