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。
Network simulator version 2 （NS-2） is used more and more widely for research on satellite net- work. 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 a- nalysis of satellite network simulation principle and approeh. Simulation modules of a new space commu- nication node, link and geometry characteristic are designed with C ＋ ＋ programming language in NS-2 core. And the interfaces of the new space communication node simulation modules are designed with Tcl/ Tk programming language. Simulation results show that the proposed extension method is feasible and elfective.
