应急通信中异构无人机中继性能仿真评估

Simulation and Evaluation of Relay Performance of Heterogeneous UAV in Emergency Communication

无人机基站能够在复杂地形和环境下快速高效部署,协助地面通信系统,满足应急通信需求。然而,现有的研究并未考虑到UAV基站的回传链路设计。可移动的UAV基站是部署在低空中,UAV基站无法采用传统的光纤链路进行数据回传,必须依靠无线链路。针对现有无人机基站回传链路的问题,提出了异构无人机中继组网系统模型以及关键的隧道技术,并从服务速率以及业务延时两个方面分析了无人机异构中继组网性能。通过仿真异构无人机中继承载数据以及语音业务性能,论证了无人机异构中继能够提升用户的业务体验。

Unmanned aerial vehicle(UAV)relays can be deployed quickly and efficiently in complex terrain and environment to assist terrestrial communication systems and meet emergency communication needs.However,the existing research does not consider the return link design of UAV base station.The mobile UAV base station is deployed in the low air,so the UAV base station cannot use the traditional optical fiber link for data return,and must rely on the wireless link.Aiming at the existing problem of UAV base station return link,this paper proposed the heterogeneous UAV relay networking system model and the key tunnel technology,and analyzed the performance of UAV heterogeneous relay networking from two aspects of service rate and service delay.By simulating the performance of heterogeneous UAV relay carrying data and voice services,it is demonstrated that heterogeneous UAV relay can improve the user's business experience.
