| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Recently, there have been proposed cloud-based vehicle control systems collect sensor information from vehicles and control them from cloud data center and MEC-based vehicle control systems that control vehicles utilizing ultra low latency. We have proposed a layered vehicle control system[1],[2] taking advantage of both cloud and MEC based systems where we enable coordinated control between Upper Edge Server (UpES) that aggregates sensor information from a large number of vehicles, and Lower Edge Server (LoES) that processes the sensor information in low latency feedback loop. The proposed system, however, has not been sufficiently evaluated using actual delay information in real world. In this report, we evaluate our proposed system using real latency data taken from various MNO and MVNO operators in Japan. In more detail, we measure the actual latency between various cloud services and UE and show that communication service quality is highly dependent on carriers and differs significantly. In addition, we simulate the proposed system using the measured latency and evaluate the effectiveness of our coordinated control. While there is inherent tradeoff between the number of vehicles to be optimized and the feedback latency in control, we show that by adjusting the location of UpES, our system can provide the optimized coordination between LoES and UpES mediating the tradeoff between the scope and the latency of vehicle control according to the requirements for the vehicle control. | |
