Unmanned aerial vehicles (UAVs) or drones have recently drawn significant attention due to their numerous potential civilian and military applications. From wireless communications point of view, UAVs can act as flying base stations (BSs) to improve the coverage and capacity of existing wireless networks. Line-of-sight (LoS) connectivity toward the users is one of the key features of UAVs which leads to the coverage enhancement compared to the traditional wireless networks. UAVs can also be useful in Internet of Things (IoT) applications, where devices have constrained transmit power to communicate over a large distance and UAVs can act as relays to deliver the IoT data to the intended receivers. Self-organizing autonomous UAVs can potentially improve the performance of existing wireless networks by several order of magnitudes (in terms of coverage, spectrum utilization, and reliability) to enable them to support the ever-increasing mobile data traffic for future wireless IoT. Despite the numerous potential benefits the UAVs can bring, there are grand technical challenges that must be addressed for the implementation of UAV-aided wireless communications systems. Among them, propagation channel modeling for UAV-aided communications, deployment and trajectory planning for UAVs, energy-efficient design of UAV systems, radio resource (e.g. bandwidth and power) allocation to UAVs, and user association are the most crucial ones. In this talk, I will provide an overview of the state-of-the-art of UAV-aided wireless communications. Then I will describe a multi-tier drone cell network architecture and present some simulation results on the coverage and capacity of such a network obtained based on the spatial point process modeling.
