Recently, unmanned aerial vehicles (UAVs) have been reported a lot as aerial base stations (BSs) to assist wireless communication in Internet of Things (IoT). However, most results for UAV deployment require uniform access requirements and obstacle-free environment.
Location moving process of air base stations using DQN algorithms. After a certain scale of learning, the network structure parameters of DQN algorithm are obtained and saved as a model. When the model is directly applied in this scenario, the aerial-BSs will stay in the optimal position of system spectrum efficiency.
In addition to the advantages of large bandwidth and high-speed rate, millimeter wave has narrow beam, good directivity, and high spatial resolution, which improves the transmission efficiency, so mmWave transmission suitable for direct communications can be a feasible method here.
