摘要
Ad hoc网络是一种无需依赖于事先布设的基础设施,而仅依靠网络内部节点之间的协作,就能够完成节点间通信的网络。比较了Ad hoc网络两种主流的按需路由协议:动态源路由协议,自组网按需距离矢量路由协议。使用基于ns-2的仿真模型进行仿真,并通过分组交付率、平均端到端时延、标准化路由负荷、对两种按需路由协议进行评估。实验结果表明即使DSR和AODV协议都是按需路由协议,但它们采取的路由机制的不同,导致它们的性能表现的巨大差异。
Ad hoc networks are self-organizing networks that can be organized anywhere and at any time without the aid of any established infrastructure and centralized administration.The two on-demand routing protocols for mobile ad hoc networks are compared,that is,Ad Hoc On-Demand distance Vector Routing(AODV),Dynamic Source Routing(DSR).These two on-demand routing protocols are simulated and evaluated with ns2 network simulation software on packet delivery ratio,average end-to-end delay,normalized routing load.Experiment indicates that although DSR and AODV have a similar on-demand behavior,their different protocol mechanisms lead to significant performance differences.
