DOI: 10.1109/taes.2019.2893082
Abstract: Current studies on unmanned aerial vehicle (UAV) based cellular deployment consider UAVs as aerial base stations for air-to-ground communication. However, they analyze UAV coverage radius and altitude interplay while omitting or over-simplifying an important aspect… read more here.

DOI: 10.1109/tvt.2022.3208839
Abstract: In this paper, we consider an unmanned aerial vehicle (UAV)-powered wireless sensor network (WSN) in which a UAV transfers wireless energy to ground sensor (GS) nodes using a directional antenna, and the GS nodes use… read more here.
