基于NS2和STK的卫星动态组网仿真与演示的研究

首先对NS2与TCL语言、STK与Connect接口进行了概述,阐明了其特点。为了较好地对卫星动态组网进行仿真和演示,提出基于NS2和SIX的卫星动态组网演示平台的设计框架;给出“NS2＋STK＋VC”仿真数据分析演示平台的设计流程,并提出仿真同步机制的两种实现方式,即STK时钟基准和HLA／RTI时钟基准。最后通过NS2的仿真输出实例,说明了NS2收集仿真输出结果数据的方式。此演示平台可直观地演示卫星动态组网的过程,可更好地指导卫星通信链路、卫星通信网络的设计。

Research on the Simulation and Demonstration of the Dynamic Buildup of Satellite Network Based on NS2 and STK

NS2 and TCL language,STK and Connect interface are summarized,their characters are illustrated.In order to simulate and demonstrate well the dynamic buildup of satellite network,the designing framework of the demonstration platform of the dynamic buildup of satellite network is put forword.The design flow of "NS2+STK+VC"simulation data analysis and demonstration platform is given,and two kinds of the realizing way of simulation synchronization mechanism are put forword,they are STK clock benchmark and HLA/RTI clock benchmark.Through the simulation output example the way in which NS2 collects simulation output result data is explained.The demonstration platform can intuitionisticly demostrate the process of the dynamic buildup of satellite network,it can direct well the design of satellite communication link and communication network.
