摘要
在分析了Ad Hoc路由协议的基础上,提出了较为清晰合理的Ad Hoc路由协议性能评价标准。使用NS2仿真软件对Ad Hoc网络三种经典路由协议DSDV、DSR和AODV进行了仿真数据分析,比较了它们的平均端到端时延、包投递率、路由开销以及能量消耗等性能指标。仿真结果表明在节点移动速度增加、节点停留时间变短的情况下,三种路由协议性能都有着不同程度的下降,但AODV协议的稳定性要好于DSR和DSDV。
In the base of alanysising the ad hoc routing protocols,give a more clear and reasonable performance evaluation criteria of the ad hoc routing protocols . And using ns2 alanysis three sutra ad hoc routing protocols dsdv, dsr and aodv, comparison to their average end -to -end delay the package delivery ratio, route expenses and energy consumption. Simulation results indicate when the node movement speed and the node residence time shorten, three different routing protocols performance degradation, but the aodv agreement stability is better than dsr and dsdv.
