| 摘 要： | 网络仿真器NS-2在卫星网络研究中得到越来越多的应用,但NS-2中基本的卫星网络仿真模块难以满足实际复杂场景的仿真要求.在分析卫星网络仿真原理的基础上,提出了一种卫星网络仿真模块的扩展方法.该方法深入NS-2仿真器内核,用C++语言设计了新型空间通信结点、链路以及空间几何特性仿真模块,用Tcl/Tk语言设计了新型空间通信结点的仿真配置接口.仿真实验表明,对卫星网络结点和链路仿真模块的扩展方法是可行的和有效的.

| Abstract: | Network simulator version 2(NS-2) is used more and more widely for research on satellite network.However,basic simulation module of satellite network is not able to satisfy the practical complex network simulation.An extension method for satellite network simulation module is proposed based on analysis of satellite network simulation principle and approch.Simulation modules of a new space communication node,link and geometry characteristic are designed with C++ programming language in NS-2 core.And the inte... |
