面向星地融合网络的星上管控节点动态部署方法
Dynamic Deployment Method of Satellite Management and Control Nodes for Satellite-Terrestrial Integrated Networks
摘要
Abstract
Aiming at the problem of high dynamics of low earth orbit satellite network nodes,a dynamic deployment method of satellite management and control nodes for Satellite-Terrestrial Integrated Networks is proposed.First,based on the complex and changeable structure of the Satellite-Terrestrial Integrated Networks and the limited processing capabilities of satellite nodes,a Satellite-Terrestrial collaborative network architecture with master-slave collaborative management and control is designed.Secondly,a satellite management and control node deployment model is proposed.This model takes the satellite management and control node deployment cost as the optimization objective function,and comprehensively considers constraints such as business QoS and network load.It aims to improve the response delay of satellite networking by optimizing the number and location of satellite control nodes.Finally,the reinforcement learning method is used to quickly solve the number and deployment locations of satellite control nodes under different network topology states.The simulation experiment analyzes the comparative results of the algorithm in this article,the Accelerated Particle Swarm Optimization(ASPO)and the Optimal Search(OptSearch)Algorithm in terms of the number of dynamically deployed control nodes on the satellite and the average network response delay,thereby verifying that the algorithm in this article has certain advantages in the deployment of on-board control nodes.关键词
