摘　　要：为解决路由算法对卫星通信拥塞情况处理不及时导致卫星系统的吞吐量、时延和丢包率等性能的影响,提出一种基于LEO卫星通信的拥塞预测方案。该方案是利用卫星进行区域判断,识别自己是否处于拥塞区域。处于拥塞区域时可获取相关区域的信息,并分享其位置信息,实现相邻卫星针对拥塞区域信息的实时交互以达到预测拥塞,减少拥塞区域的交通负荷的集中。实验结果表明,利用该方案的路由算法相较于利用之前的方案或策略的路由算法,对整个卫星通信系统在吞吐量、时延和丢包率方面的性能有所提高。To solve the impact of delayed handling of satellite communication congestion by rou-ting algorithms on the throughput,latency,and packet loss rate of satellite systems,a congestion prediction scheme based on LEO satellite communication is proposed.This scheme uses satelltes to make regional judgments and identify whether one is in a congested area.When in a congested area,information about the relevant area can be obtained and its location information can be shared,enabling real-time interaction between adjacent satellites regarding congested area infor-mation to predict congestion and reduce the concentration of traffic load in congested areas.The experimental results show that the routing algorithm using this scheme has improved the per-formance of the entire satellite communication system in terms of throughput,latency,and pack-et loss rate compared to the routing algorithm using previous schemes or strategies.
