Clustering Users for the Deployment of UAV as Base Station to Improve the Quality of the Data

Unmanned aerial vehicle (UAV) is a promising technology for mitigating Terrestrial Base Stations failures or even becoming an ideal temporary solution to offloading. UAV as Base Stations (UABS) can be deployed to complement existing cellular systems by providing additional capacity to hotspot areas as well as to provide network coverage in emergency and public safety situations. In terrestrial cellular networks, mobile devices at the cell edge often pose a performance bottleneck due to their long distances from the serving terrestrial base station (TBS), especially in the hotspot period when the TBS is heavily loaded. Simulation results show the gains of the proposed offloading scheme (OS) by improving the throughput, and quality of service (QoS) compared with a conventional LTE overloaded network.
