Spatiotemporal Correlation Representation based Precise Resource Management in Space-Air-Ground Integrated Network
摘要
Abstract
In the space-air-ground integrated network,resources are unevenly distributed and dynamically change over time.Traditional optimization scheduling methods based on static resource representation only optimize scheduling within a single time slot,leading to low resource utilization.Moreover,frequent strategy adjustments are required when the network changes,resulting in significant migra-tion costs.To address this issue,this paper proposed a method for spatiotemporal correlation representation of resources in the space-air-ground integrated network.This method computed node attention representations in both structural neighborhoods and chron-ological neighborhoods,enabled precise modeling of spatiotemporal resource correlations in the space-air-ground integrated network.Based on this,this paper proposed a resource precise embedding method based on spatiotemporal correlation representation,and intro-duced the trust region policy optimization method to adaptively learn and optimize algorithm parameters.关键词
