摘要
研究了在分层分域卫星网络结构下的用户接入问题,包括网络节点编址、用户位置信息注册和更新、多星接入策略等,通过比较几种单层卫星网络常用的多星接入策略,提出了多层卫星网络的多星接入策略,最后对提出的接入策略在双层卫星网络上进行了仿真分析,得出了接入策略适用于分层卫星网络的结论。
The access strategy is studied for multi-layered satellite networks, which includes node addressing, user location registering and updating, and selecting methods for multi-satellites. By comparing several selecting methods for multi-satellites commonly used in single-layered satellite networks, the selecting methods for multi-satellites in multi-layered satellite networks are put forward. Further- more, the access strategy proposed was analyzed through simulation of a layered satellite network to come to a conclusion that the pro- posed access strategy is fit for multi-layered satellite networks.
