摘要:

无人机搭载通信设备升空作为空中基站,具有灵活机动、部署迅速等特点,合理地部署无人机基站可以有效提升网络的覆盖与容量。与传统的移动通信网络相比,无人机通信网络性能不仅受到无人机基站部署密度的影响,还与无人机的飞行高度有关。通过搭建无人机通信的系统级仿真平台研究了不同场景下无人机通信网络中各参数对网络容量与覆盖能力的影响。仿真结果表明,无人机密度增加,会提升网络容量及覆盖;相同无人机密度下,网络容量随着无人机飞行高度增加先增后减。

关键词: 无人机网络, 覆盖, 网络容量

Abstract:

Unmanned aerial vehicle(UAV) equipped with communication equipment,as air base stations,can enhance the coverage and capacity of the communication network effectively,due to the characteristics of flexible and rapid deployment.Compared with the traditional mobile communication network,not only the deployment density,but also the flight height of UAV has an influence on the performance of UAV communication networks.The influence of the parameters of UAV communication networks on capacity and coverage was studied.Through the system level simulation,with the increase of UAV deployment density,the capacity and coverage of the UAV communication network have been significantly improved.With the increase of UAV flying height,the capacity of the network shows a trend of increasing firstly and then decreasing.

Key words: UAV network, coverage, network capacity
