Simulation-based Assesment of Quality of Service in UAV-assisted mmWave System in Crowded Area

In this paper, we assess the applicability of millimeter wave (mmWave) system with mmWave-enabled unmanned aerial vehicle (UAV-BS) in crowded area using the NS-3 simulation tool. We simulate the transmission at 28GHz between the base station (BS) and the user terminal (UT). The BS and the UT are located in opposite corners, and the UAV is located in the middle of the square. We measure end-to-end quality of service metrics at the remote host for scenarios with UAV and without it for various densities of blockers. The relaying using UAV-BS demonstrated the gain in goodput metric up to 80% for the scenario with high blockage. The remarkable properties of mmWave system are considered using 10OMbps UDP stream from the UT to the remote host.
