Abstract
In this study, subband assignment to base stations (BS) and simultaneous optimization of the three-dimensional positions of unmanned aerial vehicles (UAVs) in a multi-cell network supported by UAVs were performed using a genetic algorithm (GA). The aim of the optimization is to maximize a total speed metric that prioritizes edge users (UEs) (based on max-min fairness) at the cell edge. The proposed GA was compared with improved greedy and greedy+local lookup methods. Simulations for different cell radii show that the GA outperforms both methods in terms of total speed and max-min fairness; it improves service quality, especially in large cells, by more effectively directing edge users to UAVs.
Simulation of three typical UAV dispatching problems shows that greedy algorithm has better optimization in resource utilization and the convergence of the simulated annealing algorithm is better under the complex constraints.
