Ad Hoc网络路由协议性能研究

文章对AdHoe网络中的三种路由协议（DSDV、AODV和DSR）进行了分析和比较，并通过NS-2仿真软件，对三种协议进行了仿真。通过分组传递交率、端到端延迟和路由负载等指标，对协议在不同环境下的性能进行了分析和比较，并详细讨论了仿真结果。结果显示，AODV和DSR协议的总体性能要优于DSDV协议，而AODV和DSR则各有优缺点，分别适用于不同的应用环境。

Research on Performance of Ad Hoc Network Routing Protocols

The paper analyses three kinds of Ad Hoc networks routing protocols （DSDV.AODV and DSR） and makes a comparison to them. Using NS-2 simulating platform, the paper simulates routing protocols. Also, the paper discusses the simulating result through the comparison of the protocol in different circumstances by the quantitative analysis and comparison to the indexes of packet delivery fraction,end-to-end delay and routing overload. The result shows that, it can be concluded that performance of AODV and DSR is better than DSDV. Moreover, AODV.DSDV and DSR have respective advantages and disadvantages, which can be applied to different application.
