低轨通信星座分域网络感知优化方法
Optimization Method for Network Awareness in Different Domains of LEO Communication Constellation
摘要
Abstract
The heterogeneous and time-varying characteristics of network resources in LEO communication constellation,as well as the diversities of service requirements,make it difficult to allocate network resources.Therefore,efficient network awareness optimization methods are urgently needed.For cold domain with lower load pressure,a multi-source dynamic awareness domain partitioning and ef-ficient awareness aggregation algorithm is proposed.By dynamically solving the optimal active awareness path within the domain,the awareness range is expanded to support the improvement of network awareness capability.For the hot domain with higher load pres-sure,a stepwise optimization algorithm based on on-board queue resource awareness is proposed,which reduces awareness overhead and reporting time by respectively optimizing node awareness frequency and the selection of reporting nodes,ultimately supporting the awareness optimization of cold and hot domains in the constellation.关键词
