A Cooperative Scheme for Unmanned Aerial Vehicles in Malfunction Areas

Abstract

This paper studies the application of the unmanned aerial vehicles (UAVs) to a malfunction area. Note that the ground base stations (GBSs) inside the malfunction area are broken, whereas the GBSs outside work well and are distributed according to a homogeneous Poisson point process (HPPP). A user-centric cooperative scheme is proposed to serve the user equipments(UEs) in the malfunction area. Specifically, based on the UEs’ connections to the UAV and nearest GBS, the users in the malfunction area can be served by the UAV only, both the UAV and the nearest GBS or the nearest GBS only. The proposed scheme can be tuned by a parameter î'. Analytical framework is developed to obtain the expression for the coverage probability achieved by a UE in the malfunction area, which is verified by computer simulations.
