基于NS的移动网络仿真研究

Mobile Network Simulation Research Based on NS

仿真技术在现代通信网络设计中的作用越来越大,为了在仿真环境下对网络协议进行性能评价,必需对仿真结果进行有效的分析和处理。文中通过介绍网络仿真软件NS体系结构及安装过程,并结合具体仿真实例,着重讨论了其在移动网络仿真过程中的应用。在分析NS的跟踪输出格式的基础上讨论了仿真结果的处理,这对于NS软件的使用及网络协议的研究具有较强的实用价值。

Simulation is playing the more and more important role in designing of modern telecommunication network.In order to evaluate the performance of network protocols in simulating environment,must analyze and process carefully the simulating results.The paper firstly introduces the hierarchical architecture,and how to install NS,then discusses its application in the process of mobile network simulation with a simulation example.Finally,analyze the mechanism of trace and discuss how to process the simulating results.The paper is quite useful for how to use NS and network protocol research.
