| Resumen |
Cellular systems are typically designed to provide high coverage in a certain region with low blocking probability (0.02 or lower) in order to provide an adequate Quality of Service (QoS). However, when traffic peaks occur, this blocking probability increases beyond this acceptable value and the system offers an unacceptable QoS. In order to avoid the installation of additional channels in the base station, that would be active all the time, even when the traffic load is low, the use of Unmanned Aerial Vehicles (UAVs) can reduce energy consumption and alleviate traffic from the base station temporarily. We believe that this alternative is aligned with Green Communication Networks while efficiently solving the problem of higher traffic loads due to abnormal user concentrations. UAVs can also be used to assist WSNs by gathering information directly from the nodes, avoiding expensive transmissions to a fix far away sink. To this end, we develop a simulation model to calculate the hovering times of different commercial UAVs to evaluate the possibility of using these mobile base stations and sinks in future applications in wireless communications systems. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
