Efficient Multiple UAV Deployment for Maximizing Connections with Non-Uniformly Distributed Users

This paper considers the problem of determining the optimal flying locations for multiple UAV base stations to maximize the number of connected users. We consider the case of non-uniformly distributed users. We propose an adhoc approach to find optimal 3D UAV placement using a gravity inspired clustering algorithm and a two-tier connectivity model. We compare our proposed approach with existing approaches and show that our proposed approach has significantly higher expected number of connected UEs than existing approaches.
