  Mobile phone network performance has been improving year-by-year, and attention is now being paid to the utilization of such devices at sea, which has not been extensively explored to date such as remotely vessel controlling and autonomous ship. Wireless communication technology is important for these systems, and it is known that available on the coastal waters, however communication at sea does not achieve sufficient performance compared to use on land.
  In this research, we have developed a multi-path communication control method that can achieve good communication quality at sea. (1) Development of a multi-path communication control method that simultaneously uses multiple lines based on actual communication environment measurement at sea (performance survey by LTE band) and the results. (2) Development of high-definition video transmission and data volume reduction method assuming remote control using machine learning.

• Hybrid-node based IoT network architecture

  Project Period (FY)： 2016/04  -  2019/03  Investigator(s): Ohshima Kohta

  The relay propagation type IoT system using the short distance wireless link has a problem that the route to the sink node is lost due to the node failure, and it takes time to grasp the failure occurrence point. In this research, we have developed an effective network architecture by deploying hybrid nodes equipped with mid- and long-range wireless communication functions in part of the IoT system in addition to short-range wireless communication. This method can manage a large-scale relay propagation type network in a subnetwork unit by the hybrid node and has high management and operation performance. Communication control based on the investigation of the site-specific communication environment and operation verification using a prototype system were carried out.
