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.
