| 摘 要： | 移动自组织网络（Mobile Ad hoc Network,MANET）的一个典型特点就是网络拓扑结构的动态变化,这个特点造成了在通信过程中路由的频繁切换。而路由频繁切换的过程往往会给上层的服务应用带来不利影响。以在移动场景中综合性能最优的AODV（Ad hoc on-demand distance vector）协议为研究对象,通过NS2仿真分析了在一个连接运行过程中路由切换的特点,包括路由切换的触发原因、切换时延、切换丢包率等因素。该文对路由切换性能的详细分析结果为将来优化路由维护策略及提升路由切换效率提供了参考和依据。

| Abstract: | The typical characteristic of MANET(Mobile Ad hoc Network) is the dynamic network topology,which leads to frequent route changes in correspondent progress.This phenomenon will generate defective affects to up layer applications.The characteristics of route handover are studied in this work through NS2 simulation by using AODV(Ad hoc on-demand vector)routing protocol.The evaluation metric includes route handover delay,route handover packet loss and the reasons for them.There aren't any literatures considerin... |
