Coverage of UAVs Base Station with Deployment Following by Ginibre Point Process

Unmanned Aerial Vehicles (UAVs) can be used as communication access points or base stations serving ground and airborne users. In this paper, we focus on the connectivity of ground users corresponding to an airborne base station. Most of the existing studies on UAVs network assume using omnidirectional antennas and model the distribution of UAVs according to the Poisson point process. The multiple air-toground dominant line-of-sight channels overlap the coverage areas and introduce severe co-channel interference. To reduce the interference, this paper models the distribution of UAVs with $\beta$-GPP and using directional antennas. Correspondingly, an approximate expression for the network coverage probability is derived using the results of the random geometry. The simulation results show that deploying UAVs according to the -GPP model and the appropriate setting of directional antenna beamwidth can effectively improve the coverage probability.
