Wireless networks equipped with unmanned aerial vehicles (UAVs) as airborne base stations have become a promising technology to increase the coverage area of ground users. When users move at high speed in the coverage area of a UAV wireless network, an efficient handover algorithm is required to maintain the users’ quality of service. On the other hand, the network load should be fairly distributed among the base stations to avoid crowded stations and stations without service. This paper presents an efficient algorithm for selecting the target base station in the handover process for mobile users in UAV-based wireless networks. The proposed algorithm satisfies the quality of service required by the users in the coverage of the new base station while reducing the number of unnecessary handovers between the base stations and distributing the load among them fairly. The simulation results show that the proposed method performs better than the conventional handover schemes.
