The use of Unmanned Aerial Vehicles (UAVs) has gained interest in wireless\nnetworks for its many uses and advantages such as rapid deployment and\nmulti-purpose functionality. This is why wide deployment of UAVs has the\npotential to be integrated in the upcoming 5G standard. They can be used as\nflying base-stations, which can be deployed in case of ground Base-Stations\n(GBSs) failures. Such failures can be short-term or long-term. Based on the\ntype and duration of the failure, we propose a framework that uses drones or\nhelikites to mitigate GBS failures. Our proposed short-term and long-term cell\noutage compensation framework aims to mitigate the effect of the failure of any\nGBS in 5G networks. Within our framework, outage compensation is done with the\nassistance of sky BSs (UAVs). An optimization problem is formulated to jointly\nminimize communication power of the UAVs and maximize the minimum rates of the\nUsers' Equipment (UEs) affected by the failure. Also, the optimal placement of\nthe UAVs is determined. Simulation results show that the proposed framework\nguarantees the minimum quality of service for each UE in addition to minimizing\nthe UAVs' consumed energy.\n
