基于OPNET的卫星网络仿真平台设计

卫星网络采用无线信道进行通信,使得在仿真设计时存在一定的困难并且工作量较大。该文采用了一种近似方法,利用现有技术成熟的地面网络来模拟卫星网络。通过对通信链路定时通断及其属性的设置充分体现了卫星网络的移动性、动态性和传输时延大等特点。并用OPNET网络仿真软件建模并得到了仿真结果。此方法在仿真开发初期是一种切实可行的设计方法。

OPNET Based Scheme of Satellite Network Simulation Platform Realization

Satellite network communicates with wireless channels,which makes simulation design have some difficulty and needs a mount of work.This paper introduces a near method.It uses the maturity technology of ground network to simulate satellite network.Letting the links on or off timely and setting their properties,the simulated network can sufficiently embody the mobility,dynamics and large transmission delay of satellite network.Then it models with OPNET network simulation software and gets simulation results.It is a feasible design method in the initial exploitation stage of the simulation.
