Embodiment
[0202] In the simulation scenario in this embodiment, it is assumed that there are 5 sensors randomly distributed in an area of 100mx 100m, the height of the BS is 30m, and it is located at the origin of the coordinate system. The charging piles are distributed at the centroid of the sensor with a height of 20m. Simulation results compare the proposed scheme with resource allocation algorithms under circular trajectories. In the comparison algorithm, the UAV takes the midpoint of the base station and the charging pile as the center, flies in a circular trajectory with a radius of 20m, and optimizes the time slot allocation and power allocation. Among them, in order to optimize the energy collection efficiency of the UAV, the UAV uses h altitude flight. The parameter settings in the simulation process are shown in Table 1.
