Abstract:

In this paper, we investigate a laser-charged un-manned aerial vehicle (UAV) relaying network where a rotary- wing UAV relays data from a ground base station (GBS) to a user equipment (UE), and a charging station (CS) transmits a laser beam to charge the UAV. Instead of using a simplified propulsion power consumption (PPC) model for UAVs, which was widely used in the previous works on the laser-charged UAV relaying networks, we leverage an intractable but more accurate PPC model for UAVs. We study an optimization problem of minimizing the power consumption of the CS while satisfying the UE's minimum data requirement, and we develop an algorithm to solve this problem by jointly optimizing UAV trajectory and charging power. Through simulation, we demonstrate the effectiveness of our trajectory and charging power control algorithm and validate the importance of leveraging the accurate PPC model for UAVs rather than using the simplified one.
