LEO卫星网中基于地理位置的分布式动态路由算法的研究

Research on the Geographical-Position-Based Distributed Dynamical Routing Algorithm for LEO Satellite Network

LEO卫星网络中进行信息交换,首先要解决的就是星际链路网络上路由问题,而运行于地面网络的路由算法,在卫星网络中并不适用.将针对LEO卫星网络星际链路的特点进行深入研究,提出一种新型的符合LEO卫星网络拓扑高速变化等特点的基于地理位置的分布式动态路由算法,并构建地面网络对该算法和现在流行的路由算法的性能进行仿真验证和比较,证明我们提出的新型动态路由算法能适应LEO卫星网络环境,能够提供较好的通信质量,就有较短的通信时延.

The Routing is the most prominent issue, which should be solved firstly to support information exchange in LEO satellite network. But those Routing algorithms running well on ground network are not able to adapt to satellite network. In this article,we focus on the research of the characteristics of LEO satellite network and provide a new distributed dynamical routing algorithm based on geographical-position for LEO satellite network. We also constructed the simulation environment to validate the routing algorithm, which was testified to fit the LEO satellite network very well.
