Research on update period estimate of satellite network topology based on characteristic of link
基于链路特性的卫星网络拓扑更新周期研究

Aiming at the problem of the interval partition of satellite network topology updating, put forword a method of the updating period estimate of satellite network topology based on the characteristic of link. First, put forword three models to fulfill the modeling of updating period of satellite network topology, the models were as follows: the model of the coverage time of satellite, the model of the characteristic of link and the model of the updating period estimate of satellite network topology, then the simulation of the satellite of different constellations was done to validate the method, achieved the updating period estimate of satellite network topology by the synthetic research of coverage time, time delay skip and the characteristic of link, provided the view of research from the characteristic of link to network topology and routing computing, and through network topology, connected the characteristic of link and routing computing with each other integrally, which had direction for the effective design of satellite network.
