LEO巨型卫星网络端到端路由机制研究OA

Satellite communication networks composed of low earth orbit mega-constellation network needs to solve the end-to-end rout-ing problem between ground terminals through direct satellite connections.To this end,the characteristics of low-orbit mega-constellations are first analyzed,and a mobility and handover management mechanism based on space-ground integrated network is pro-posed.At the same time,a location-oriented intelligent giant satellite network routing algorithm LoISR is proposed to solve the end-to-end full-path communication problem in space-ground integrated network.The proposed algorithm collects benchmark routing data through simulation of the target satellite network,a machine learning model is trained based on this data,then trims and compresses the model and deploys it to satellite nodes,the feasibility and efficiency of the proposed algorithm are verified through relevant experiments.
