摘要/Abstract

摘要：

针对中继信号覆盖区域确定性模型没有考虑信道随机衰落影响的问题，提出了一种基于中断概率的无人机（UAVs）中继平台信号覆盖半径统计模型。通过将中继链路建模为包含路径损耗、阴影衰落和多径衰落的复合分布模型，推导获得中继信号覆盖半径的概率分布，并给出一种利用中断概率数值求解覆盖半径的方法。仿真结果表明，信道衰落对覆盖半径影响非常大，当中断概率小于10%时，覆盖半径仅为无衰落信道时的一半。研究结果对移动自组织网络（MANETs）中的中继网络的无人机最优布置、飞行策略以及网络性能评估等具有重要的参考价值。

Abstract:

Traditional area coverage models for the airborne relay of mobile ad-hoc networks (MANETs) fail to take the channel fading into consideration. A new statistical area coverage model is proposed in this paper based on the outage probability for wireless relay communications with unmanned aerial vehicles (UAVs). Firstly, the fading of the relay channel, including path loss, shadowing and multipath fading, is modeled by composite fading distribution. Then, an expression in the form of outage probability for coverage radius is derived and a numerical computation method is provided. The simulations show that channel fading has a great effect on coverage radius, which is only half of the radius in a non-fading situation when the outage probability is below ten percent. These findings are of considerable significance for optimal UAVs arrangement as well as the flight control and performance analysis of the relay networks with UAVs.

Key words: unmanned aerial vehicles (UAVs), mobile ad-hoc networks (MANETs), relay platform, coverage area, channel modeling, outage probability
