Abstract
The high density of temporary hotspots will result in a significant reduction in data rates per user. In addition, when base stations are no longer functional in the disaster area, it is necessary to develop wireless infrastructure as soon as possible. To address this situation, we focus on UAVs (Unmanned Aerial Vehicles) equipped with wireless communication infrastructure to provide services. Building a wireless network with mobility, UAVs can provide high data rates for ever-changing user distribution. In this paper, for dynamic user distributions, which have not been considered much so far, we identify issues due to differences from static user distributions and propose methods to solve them. This paper reports on the study of UAV placement method from the viewpoint of data rate and power consumption.
