ABSTRACT
Unmanned Aerial Vehicles (UAVs) are transforming cellular networks, extending coverage to underserved regions and enabling swift deployment of communication infrastructure. However, the dynamic nature of UAVs poses challenges in user association and resource allocation. To address this, we introduce dynamic user association and resource allocation technique for UAV-assisted cellular networks. This technique leverages UAV trajectory data to optimize user connections, enhancing SINR for uninterrupted, high-quality connectivity within UAV coverage. Dynamic resource allocation, using the Resource Allocation Metric (RAM), efficiently manages UAV transmit power based on parameters like active UEs, individual activity duration, social priority, data volume, and battery life. Through comprehensive analysis and simulations, the proposed technique consistently outperforms conventional techniques in SINR and system throughput.
