基于环境可靠性预测的低轨卫星网络弹性智能路由技术OA

Low earth orbit satellite networks face severe reliability challenges in the complex space environment,where conventional routing protocols,with their reactive mechanisms,struggle to address the link instability risks induced by space environment effects.To this end,this paper proposes a resilient and intelligent routing method for low earth orbit satellite networks,driven by environmental re-liability prediction.The method begins by designing a space environment reliability index that integrates predictable radiation risks,space weather disturbances,and real-time link communication quality,and subsequently formulates the end-to-end routing problem.Next,a message-passing-based model is constructed to aggregate neighborhood state information among satellites.This enables a col-laborative multi-agent distributed routing algorithm,guided by environmental state predictions,to facilitate a paradigm shift in routing decisions from reactive response to proactive avoidance.Simulation results demonstrate that,compared to baseline algorithms,the pro-posed method can proactively avoid high-risk regions,significantly enhancing the end-to-end routing reliability of low earth orbit satel-lite networks in dynamic space environments.
