基于 OPNET 的 AODV 与 DSR 协议的性能分析

摘要

Ad Hoc 网络是由一组带有无线收发装置的移动节点组成的一个无线移动通信网络，它不依赖于预设的基础设施而临时组建，节点利用自身的无线收发设备交换信息，当相互之间不在通信范围内时，可以借助其他中间节点中继来实现通信。文中分析了 Ad Hoc 网络中 AODV 和 DSR 路由协议的优缺点，然后利用 OPNET 网络仿真软件搭建仿真模型，分别在10个和30个通信节点的小规模网络环境下，对 AODV 和 DSR 协议的性能进行了初步分析，为以后的研究提供依据。%Ad Hoc network is a wireless mobile communication network with a set of mobile nodes containing wireless sending and receiving device,which is set up temporarily without depending on the preset infrastructure.The mobile node utilizes its own wireless sending and receiving device to exchange information.When two nodes are beyond the communica-tion range of each other,they can realize communication with the aid of the relay nodes between them.A comprehensive a-nalysis of advantages and disadvantages of AODV and DSR,two typical Ad Hoc network routing protocols,is presented in the article,and then simulation model is built using OPNET network simulation software.In the small-scale network envi-ronment of 10 and 30 communication nodes,performance of AODV and DSR is preliminarily analyzed,which can provide a basis for future research.
