摘要
无人机可作为空中基站和中继,在缺乏通信基础设施的地域快速建立应急通信。但无人机通信范围和能源有限,控制无人机群在长时间内实现一定的通信覆盖,同时最大限度地降低能耗是一项挑战。针对此问题,提出了“四步部署策略”,采用地面中心基站、簇无人机及中继无人机对地面用户实施通信组网覆盖。仿真结果表明,与随机部署无人机通信覆盖相比,所提算法可显著提高用户覆盖率,并节约能耗。
UAV(Unmanned aerial vehicle)could serve as aerial base stations and relays to rapidly establish emergency communications in areas lacking communication infrastructure.However,UAVs have limited communication range and energy,and controlling a UAV swarm to achieve a certain level of communication coverage over a long period while maximizing energy conservation is a challenge.To address this issue,a“four-step deployment strategy”is proposed,which uses a ground central base station,cluster UAVs,and relay UAVs to achieve communication networking coverage for ground users.Simulation results indicate that compared with random UAV deployment for communication coverage,the proposed algorithm can significantly increase user coverage and save energy.
