Query: Short-term and Long-term Cell Outage Compensation Using UAVs in 5G
  Networks   The use of Unmanned Aerial Vehicles (UAVs) has gained interest in wireless
networks for its many uses and advantages such as rapid deployment and
multi-purpose functionality. This is why wide deployment of UAVs has the
potential to be integrated in the upcoming 5G standard. They can be used as
flying base-stations, which can be deployed in case of ground Base-Stations
(GBSs) failures. Such failures can be short-term or long-term. Based on the
type and duration of the failure, we propose a framework that uses drones or
helikites to mitigate GBS failures. Our proposed short-term and long-term cell
outage compensation framework aims to mitigate the effect of the failure of any
GBS in 5G networks. Within our framework, outage compensation is done with the
assistance of sky BSs (UAVs). An optimization problem is formulated to jointly
minimize communication power of the UAVs and maximize the minimum rates of the
Users' Equipment (UEs) affected by the failure. Also, the optimal placement of
the UAVs is determined. Simulation results show that the proposed framework
guarantees the minimum quality of service for each UE in addition to minimizing
the UAVs' consumed energy.
