Evaluation of Handover Probability and Handover Rate of UAVs Cellular Network

This paper deals with the characterization of mobility models for unmanned aerial vehicles (UAVs) cellular network regarding handovers. The UAVs act as base stations to serve terrestrial users using service models, namely user dependent model and user independent model. The state-of-the-art mobility models, such as straight line, random waypoint (RWP) and modified random direction (M-RD) are employed under two different mobility scenarios for UBSs: same speed model and different speed model. The RWP mobility model achieves lower bound in handover probability followed by M-RD mobility model with an infinitesimal change. The M-RD mobility model exhibiting lowest handover rate has greatly increased its usability in UAVs cellular network.
