Minimizing different error sources due to aerial base station placement problem

Abstract

Drone small cells (DSCs) which are aerial wireless base stations mounted on flying devices like unmanned aerial vehicles (UAVs) such as drones and balloons, have recently gained significant popularity as key enablers for rapid deployable relief network. These platforms are capable of providing wireless services to ground users in overloaded and high demanded cells. The efficient deployment of these DSCs while optimizing the covered area is one of the key design challenges. This project is to design the optimal altitude of a DSC to provide maximum coverage on the ground users with minimal required transmit power. In our analysis, we found out that, optimal altitude is function of the maximum allowed pathloss and depends on environment parameters as defined by International Telecommunication Union (ITU). By continuously increasing the target radius, both the optimal altitude and the transmitted power increases. This increases because of the increase in pathloss between the transmitter and the receiver.
