摘要/Abstract

摘要： 无人机网络具有按需部署、灵活机动等优势，但传统陆地蜂窝网络的分析方法不再适用.为此，考虑了两层无人机网络中地面用户的移动性，推导了系统覆盖概率、传输速率、边界的长度强度以及用户最大移动速度约束等网络关键性能指标的解析表达式，探究了无人机部署的密度、高度、地面用户移动速度对无人机网络覆盖及切换性能的影响.理论及仿真结果表明，自适应地调整无人机部署的密度和高度能有效提升无人机网络的覆盖及切换性能.

关键词: 无人机网络, 用户移动性, 随机几何, 覆盖概率, 边界长度强度

Abstract: Unmanned aerial vehicle (UAV) networks can be deployed on demand and operate flexibly. However, the analytical approach for traditional terrestrial cellular networks cannot be directly applied to the UAV networks. Against this background, this paper investigates the coverage and handover performance of the UAV communication systems. With the consideration of user mobility in a 2-tier UAV communication system, the analytical expressions of the coverage probability, the transmission rate, the boundary length intensity, and the maximum velocity constraint of users are derived. The impacts of the UAV density, height, and the velocity of user on the coverage and handover performance of system are examined as well. Analytical and numerical results demonstrate that the coverage and handover performance of the UAV networks can be effectively boosted by adaptively adjusting the density and the height of the UAVs.

Key words: unmanned aerial vehicle network, user mobility, stochastic geometry, coverage probability, boundary length intensity
