Optimization of Total Power Consumed by Flying Base Station Serving Mobile Users

Popis výsledku v původním jazyce

The unmanned aerial vehicles (UAVs) acting as flying base stations (FlyBSs) are considered as an efficient way to enhance the capacity of mobile networks. The enhancement provided by such network requires a dynamic positioning of the FlyBSs with respect to the users demands on communication. However, the power consumption of the FlyBS is a challenge due to a limited capacity of the FlyBS's power supply. In this paper, we reduce a total power consumption of the FlyBS while a required communication capacity is guaranteed to the mobile users in every time instant of their movement. To this end, we derive a closed-form solution for an optimization of the FlyBS's total power consumption in every single time step. Then, we provide a numerical solution for the total power optimization problem over a long period of the users’ movement. Via the simulations, we show that the proposed scheme reduces the overall power consumed by the FlyBS significantly (by up to 91%) comparing to existing solutions.
