摘要
Abstract
To address the communication security challenges faced by mobile users in smart grids such as remote inspection devices and mobile maintenance equipment,an unmanned aerial vehicle(UAV)-assisted mobile user communication system for smart grids based on air-ground integration is proposed.The system utilizes hybrid reconfigurable intelligent surfaces(HRIS)working in coordination with UAVs.By optimizing the beamforming at the base station(BS)and the reflection coefficient matrix of the HRIS,and employing a twin deep deterministic policy gradient(TDDPG)algorithm to solve the problem,the secrecy energy efficiency(SEE)of communication system is maximized under the constraints of total system energy consumption and quality of service(QoS)requirements so as to ensure the security and quality of data transmission for mobile services in the presence of eavesdroppers.Simulation results verify the effectiveness of the proposed model and communication strategy,with the achievable secrecy rate increased by approximately 36.8%compared with that of traditional schemes,significantly improving the security and energy efficiency of mobile service communication in smart grids.关键词
