一种卫星网络地面中继站智能休眠策略
An Intelligent Sleep Strategy for Satellite Network Ground Relay Station
摘要
Abstract
Satellite ground relay stations can effectively support regular portable mobile terminals in high-quality satellite communications.In regions without power grids,ground relay stations rely on their own photovoltaic and wind energy conversion devices for power supply,which is unstable,and their energy efficiency issues are worth studying.The authors propose an energy-saving sleep strategy for satellite ground relay stations based on double deep Q networks to address the issue of energy efficiency optimization of relay stations under conditions of insufficient and unstable energy.First,the state space,action space,and reward function of the agent are designed according to the energy consumption characteristics of the ground relay station.Then,the value learning and feature extraction capabilities of the algorithm are used to train the agent's optimal sleep strategy.Simulation results show that compared with the traditional rule-based sleep method,the proposed strategy effectively saves 21.55%of non-communication energy consumption in low-load scenarios and improves the overall energy efficiency of the relay station by 3.7%.It significantly reduces energy consumption while ensuring user service quality.关键词
