摘要
空间组网技术是卫星技术发展的重要方向之一,它能够提供全球覆盖并支持多种业务,其关键技术之一是在具有星间链路的卫星网络中进行分组路由。本文简单分析了LEO卫星网络的路由特性,讨论了在卫星环境下进行模拟仿真的方法,具体介绍了ns2对卫星网络模拟的支持,并针对两种不同的路由算法进行了模拟与分析。
Space network technology is one of the important directions of the technical development of the satellite. It can provide global coverage and support a lot kind of services. Packet routing in the satellite networks which have intersatellite links is one of its key technology. This paper analyzes the routing issues in LEO satellite networks and discusses the methods of simulation experiments for satellite networks. Introduces the ns2 support to network simulation of the satellite networks concretely and implements two simulation experiments aiming at two kinds of different route algorithms.
