Proactive traffic control based on human blockage prediction using RGBD cameras for millimeter-wave communications

This paper proposes an RGBD cameras-based wireless environment prediction and presents an implementation of a proactive traffic control system using the prediction results. In millimeter-wave and terahertz communications, frame loss rate increases and throughput is decreased tremendously when pedestrians block line-of-sight paths. Such serious human blockage does not occur in microwave communications. By using the RGBD cameras, we can predict human blockage easily as the cameras can detect obstacles and their mobility. We implement a prototype of a proactive traffic control system using camera-based human blockage prediction to demonstrate the feasibility of the proposed system.
