Abstract

This letter derives new three-dimensional (3D) mobility models and analyzes their impact on the outage performance of unmanned aerial vehicle (UAV) communications. Specifically, new hybrid mobility (HM) models for the UAV movement in 3D space are derived by merging one-dimensional (1D) and two-dimensional (2D) mobility models in the vertical and horizontal directions, employing both random distance (RD) and random waypoint (RWP) models. Then, closed-form expressions of the cumulative distribution functions (CDFs) for the random distances between ground user and the UAV are obtained. Using these CDFs, the outage probability of the UAV communications system is calculated. Numerical results demonstrate the severe impact of different mobility models on the outage of the considered system.

三维移动模型及其对无人机通信中断性能的影响

本文推导了新的三维（3D）移动模型，并分析了其对无人机（UAV）通信中断性能的影响。具体来说，通过合并垂直和水平方向上的一维（1D）和二维（2D）移动模型，同时采用随机距离（RD）和随机航点（RWP）模型，推导出了无人机在三维空间中移动的新混合移动（HM）模型。然后，得到地面用户与无人机之间随机距离的累积分布函数（CDF）的闭合表达式。利用这些 CDF 计算出无人机通信系统的中断概率。数值结果表明，不同的移动性模型对所考虑系统的中断具有严重影响。
