Abstract: The UAV-assisted wireless network is envisioned as a key player in the sixth generation (6G) wireless systems. One of the most challenging tasks to make it practically viable is to deploy UAVs considering user density, propagation environment and other factors. In traditional UAV deployment techniques, the propagation environment is hardly considered. In this paper, we propose an algorithm for deploying UAVs considering both factors in order to maximise the user throughput using the Whale Optimisation Algorithm (WOA). We formulate the UAV deployment problem as a global optimisation problem. Then, we formulate the objective function to maximise the average user throughput while satisfying several constraints. Through simulations, we show that the proposed technique outperforms the state-of-the-art UAV deployment algorithms. Up to 36% gain in the average user throughput is obtained. The proposed technique is capable of deploying the UAVs to support a certain level of minimum average user throughput requirement.
