Abstract(in Japanese) (See Japanese page)
Abstract(in English) The small coverage of road side units (RSUs) is one of the challenges in millimeter wave (mmWave) communications for autonomous vehicles. A key concept of this paper is leveraging vehicles’ position controllability to increase the coverages of RSUs by creating long multi-hop relays. Vehicles should be positioned where they can communicate with each other in line-of-sight (LOS) paths because the blockages of LOS paths is a crucial problem in mmWave communications. In this paper, a vehicle position control method based on reinforcement learning (RL) is proposed to avoid blockage and create long relays in order to increase coverage. RL enables vehicles to predict the future coverages achieved by their subsequent actions and therefore, its performance exceeds that of a conventional strategy which is used for moving control of wireless sensor networks. This paper also proposes state designs with information of relay length to improve the performance of increasing coverages. Simulation results confirm that the proposed method increase coverages even when not all the vehicles’ positions are controllable. In addition, it is shown that a RL-based strategy achieves higher performances than gradient-based strategies.
