资 源 简 介
本文主要基于单层卫星网络的缺点及GEO同步卫星的实现困难，引出LEO/MEO双层卫星网络。LEO/MEO双层卫星网络由用户层，LEO卫星层和MEO卫星层组成。用户层包括各种类型的用户终端，可以是便携和手持终端、车载和机载终端等。LEO卫星作为接入层卫星，负责与地面终端的直接通信。MEO卫星完成传输、交换和管理功能。接着用STK仿真得到较优的星座参数，确定卫星网络的物理架构。根据LEO/MEO双层卫星网络的特点设计路由协议。卫星网与现有的地面网络之间存在如此显著的差异，因此对卫星网路由协议的设计，必须充分考虑卫星网的上述特性。使各层卫星的负载分配合理路由表的计算和更新能适合卫星节点的性能和卫星网络拓扑的动态变化性。最后在OPNET中实现卫星网络从物理层到网络层的仿真。主要工作是在进程域中设计进程模块以实现网络层的协议，从而完成仿真平台的设计。
