Abstract: To boost network performance in terms of QoS, the main approach to be considered is Heterogeneous Networks (HetNet) deployment. One example of UAV-assisted network is the combination of UAV and Ground Users (GU), where GU is connected via random HetNet. This paper shows the comparative performance evaluation of random HetNet for a real communication scenario: with and without UAVs assisted. Here, work is presented into two parts: The first one explains the concept of random HetNet and Random Waypoint Mobility Model (RWPM) for better QoS. The second part investigates the comparison of QoS parameters for the GUs connected in a random HetNet assisted by UAVs versus without UAVs. After comparison, results purely describe the betterment in terms of higher throughput, lower end-to-end delay, and reduced jitter as justified with simulation results and evaluations. The paper concludes that the collaboration between UAV and random HetNet increases performance and supports better QoS.

Keywords: HetNet; UAVs; RWPM; GU; QoS.
