摘要
使用NS-2(Network Simulator Version 2)仿真软件,选取分组投递率、端到端平均时延、归一化路由开销和路由发现频率4个指标对按需距离矢量路由(AODV,Ad hoc On-Demand Distance Vector Routing)、多径按需距离矢量路由(AOMDV,Ad Hoc On-Demand Multipath Distance Vector Routing)和乌普萨拉大学开发的按需距离矢量路由(AODV-UU,Ad Hoc On-Demand Distance Vector Routing developed by Uppsala University)进行了性能仿真,通过改变节点最大运动速度和业务源连接对数分析比较这些参数对3个协议性能的影响,研究结果表明了AODV-UU协议的优越性。并提出了对AODV-UU协议的改进。
The simulation soft tool NS-2 is used and chooses the packet delivery rate, average end-to-end delay, normalized routing overhead and route discovery frequency are used to evaluate the performance of Ad hoe On-Demand Distance Vector Routing （AODV） , Ad Hoe On-Demand Multipath Distance Vector Routing（AOMDV） and Ad Hoe On-Demand Distance Vector Routing developed by Uppsala University （AODV-UU）. The effects of these parameters on the performance are analyzed and compared by changing the maximum velocity of the nodes and the CBR connection numbers. The research indicates that the AODV-UU protocol has better performance. The improvement on AODV-UU is also proposed.
