Design and Implementation of Aircraft Communication Simulation Module Based on NS-2

网络仿真器NS-2在空间通信网络研究中得到越来越多的应用。深入分析了NS-2中卫星网络结点和卫星链路仿真模块的特性。在分析卫星网络基本仿真原理和方法的基础上,以航空器通信仿真为例,给出了NS-2核心仿真模块的扩展方法,实现了航空器通信仿真模块。仿真实验研究分析了航空器的飞行对航空器与卫星之间链路切换特性的影响,证明了航空器通信仿真模块扩展方法的可行性和有效性。

Network simulator version 2 （NS - 2 ） is used more and more widely for research on space communication network. The simulation modules of .satellite network nodes and links are analysed in detail. A method of extending NS- 2 kernel module is proposed based on analysis of satellite network simulation principle and approch. As an example, the aircraft communication simulation module is designed and implemented. Simulation results show that flight of aircraft has effect on the link handoff characteristic, and show that the proposed extension method is feasible and effective.
