Research on Low-Cost Deployment and Low Energy Consumption Auxiliary Communication Methods Based on Unmanned Aerial Vehicles

Considering the limited communication of ground IoT devices in wide-area agricultural reclamation areas, this paper proposes a method of unmanned aerial vehicle (UAV) collaborative coverage to minimize the number of UAVs and UAV's energy consumption while meeting the needs of regional signal coverage. Firstly, with the goal of maximizing coverage area, the optimization of UAV cooperative coverage strategy is achieved under constraints such as UAV multi machine interference, UAV energy constraints, and node received signal-to-noise ratio. Through simulation experiments, the impact of UAV flight speed on communication energy consumption in different distance scenarios is analyzed, and energy consumption optimization is achieved in the scenario of maximizing UAV coverage area. Therefore, the multi machine collaborative coverage methods proposed in this article can meet the needs of UAV assisted enhanced communication coverage scenarios, and to some extent, improve the coverage quality of weak signal areas.
