Abstract

Abstract: Unmanned aerial vehicle (UAV) networks can be deployed on demand and operate flexibly. However, the analytical approach for traditional terrestrial cellular networks cannot be directly applied to the UAV networks. Against this background, this paper investigates the coverage and handover performance of the UAV communication systems. With the consideration of user mobility in a 2-tier UAV communication system, the analytical expressions of the coverage probability, the transmission rate, the boundary length intensity, and the maximum velocity constraint of users are derived. The impacts of the UAV density, height, and the velocity of user on the coverage and handover performance of system are examined as well. Analytical and numerical results demonstrate that the coverage and handover performance of the UAV networks can be effectively boosted by adaptively adjusting the density and the height of the UAVs.

Key words: unmanned aerial vehicle network, user mobility, stochastic geometry, coverage probability, boundary length intensity
