无线Ad hoc网络路由协议的分析比较

无线adhoc的路由算法是adhoc领域的研究难点。论文分析了四种路由协议DSDV、CGSR、AODV、DSR的机制,并进行了网络模拟试验,在网络时延、吞吐量、路由开销、平均跳数等方面进行了对比。试验结果表明按需路由在无线adhoc网络环境下具有更好的性能。

A Analysis of Routing Protocols for Wireless Ad hoc Networks

An ad hoc network is a collection of wireless mobile nodes dynamically forming a temporary network without the use of any existing network infrastructure.Some routing protocols have been implemented like Dynamic Source Routing(DSR),Ad-hoc On-Demand Distance Vector Routing(AODV).They are based on on-demand reactive policy,which are different from traditional proactive ones.This paper analyzes those protocols and compares their performance by simulation.The work is done by using ns-2's mobile extensions developed by the Rice Monarch Project.The conclu-sion is that on-demand reactive policy is better than proactive ones in ad hoc network scene.
