Resource allocation for hybrid FSO/RF satellite-assisted multiple backhauled UAVs over Starlink networks

Abstract

This letter addresses the resource allocation issue for hybrid free-space optics (FSO)/radio frequency (RF)-based satellite-assisted multiple users. Specifically, we present the rate adaptation-aided data frame allocation design for hybrid FSO/RF satellite-assisted multiple unmanned aerial vehicles (UAVs). The considered allocation scheme ensures latency fairness among UAVs serving as flying base stations (BSs). Numerical results confirm the effectiveness of the proposed solution over the state-of-the-art. Moreover, we investigate the feasibility of a case study over the Japan networks using practical SpaceX's Starlink satellite constellation.
