在真实的网络环境中分析和设计MANET（Mobile Adhoc Network）网络安全协议耗资巨大，因此开发对MANET网络安全协议进行性能分析的仿真软件具有重大意义．在分析MANET网络安全协议仿真的具体需求基础上，基于NS2设计和实现了集成可视化网络拓扑生成、安全协议配置、网络数据流的设置、攻击事件的设置、仿真脚本自动生成到攻击过程的仿真运行和协议性能的对比分析等功能于一体的仿真系统，通过对不同网络安全协议在不同攻击下仿真结果数据的延迟、控制开销、吞吐量，丢包率、包交付率和抖动等参数的对比分析，系统可实现不同adhoc网络安全协议的性能分析，系统还可动画演示协议受攻击时的节点运动信息、数据包信息、数据流信息和攻击信息等细节的动态变化过程．

Because of enormous cost of analyzing and designing MANET network secure protocols in real network environment, it has important significance to develop a simulation system that can analyze the performance of different MANET network secure proto- cols. On the basis of analyzing specific requirements of MANET network secure protocol simulation, this paper designed and implemen- ted a simulation system that integrates fuctions of generating network topology, configuring secure protocol, seting up data flows and at- tack events, generating simulation scripts automatically, running attacks and comparing protocol performance, etc.. Through the com- parative analysis to Delay, Control Overhead, Throughput, Packet Loss Rate, Package Delivery Rate, and Jitter of simulation results from running different secure protocols under different attacks, the system can realize the performance analysis to various ad hoc network secure protocols, and demonstrate the dynamic changes of a network under attacks in the form of animation.
