基于OPNET仿真平台的MANET路由协议性能分析

摘要

The particular function of MANET determines the significance of its routing protocols. For enhancing the function of the routing protocol, two kinds of typical MANET routing protocols (AODV protocol and DSR protocol) is compared in this essay. The schematization interface OPNET is adopted as the simulation tool. The conclusion which is relatively identical to the theoretical analysis was obtained after comparison and analysis of the simulation results. That is, the AODV protocol is generally superior to DSR protocol and more suitable for the larger-scaled MANET network. The simulational result presented in this essay provides some further efficient evidences to improve the routing protocol and the current protocol.%MANET的特殊性决定了其路由协议的重要性.为了提高MANET路由协议性能,通过比较现有的两种典型MANET路由协议AODV协议和DSR协议,采用图形化界面的OPNET作为仿真工具,通过仿真结果的比较、分析,获得了与理论分析基本相一致的结果,即AODV协议的性能总体上优于DSR协议,并且AODV协议更适合于规模较大的MANET网络.仿真结果为后续提出优化路由协议和对现有协议改进工作提供了有效的仿真依据.
