The deployment of unmanned aerial vehicles (UAVs) as floating base stations (BSs) has a huge impact in the field of wireless communication. Coverage area and spectral efficiency can be improved by efficiently using floating UAV base stations. Floating UAV BSs are very effective in delivering temporary ondemand services due to their flexible deployment capability. One of the major disadvantages of this model is that the Line of Sight (LoS) propagation environment causes severe interference to other adjacent cell users and UAV BSs. The effectiveness of the UAVs acting as wireless base station for the ground users is analyzed based on the outage probability of the LoS and non-LoS (NLoS) links. The outage probability of the downlink depends on both height of the UAV BS from the ground and its coverage radius. The analysis is carried out by varying the height and the coverage radius of the UAV BS. The simulation results show that the outage probability is minimum for an optimum height of 180m to 200m for a coverage radius of 500m and a Signal to Interference Noise Ratio (SINR) threshold of 10dB. |
