3-D Placement Strategy for VLC Enabled UAV Network with Guaranteed QoS

Large gatherings may cause the existing radio frequency (RF) network to reach its user capacity limit in the deployment area. So, to provide reliable communication to the users, we can deploy visible light communication (VLC) enabled unmanned aerial vehicles (UAVs) as an auxiliary network to the existing RF infrastructure. Our paper proposes a strategy for the efficient deployment of these VLC-enabled UAVs. It ensures the guaranteed quality of service without inter-UAV interference and does not violate the UAV’s user capacity limit. We compare the performance of the proposed algorithm for VLC-enabled UAV network with random, genetic, and K-means deployment algorithms in terms of outage and number of VLC-enabled UAVs for a fixed number of user equipments. Further, we performed an exhaustive analysis concerning the variation of irradiance and illumination with the different UAV parameters like altitude and coverage radius.
