两种无线Mesh网络路由协议仿真与性能比较

当前,对无线Mesh网络(Wireless Mesh Network,WMN)研究的主要方向之一就是无线路由技术。主要分析研究了无线Mesh网络AODV和AOMDV路由协议,并利用NS2网络仿真软件,分别在不同运动速度、不同业务负载、不同节点数目以及不同拓扑变化下对这两种路由协议进行了仿真。最后,从分组投递率、端到端平均时延和路由发现频率三个方面进行了详细分析,比较总结出了各自的优缺点。研究成果表明,AOMDV多径路由协议比AODV协议更适合于无线Mesh网络。

Simulation and performance comparison of two Wireless Mesh Network routing protocols

At present, one of the main directions to research the Wireless Mesh Network (WMN) is the wireless routing technology. This paper mainly analyzed the Wireless Mesh Network AODV and AOMDV routing protocols, then used the NS2 network simulation software to simulate the two kinds of routing protocol respectively in different speed, different traffic load, under different number of nodes and different topology changes. Finally, from three parties that include the packet delivery fraction, average end-to-end delay of data packet and route discovery frequency, a detailed analysis is used to summarize their advantages and disadvantages. Research results show that AOMDV multipath routing protocol is more suitable than AODV protocol for Wireless Mesh Network.
