| 研究実績の概要 |
In this project, we have designed and implemented context-aware network architecture is the first one that defines addressable and routable contextual information in packet trailer. It combined the benefits of data-oriented networks (such as ICN) while it supports incremental deployable in current Internet. We attach the context-info such as sensor name and sensor device id to the trailer of data packet. When packets enter into the network, the IoT routers get the context-info of the sensor data, and perform data processing accordingly. We also prototype context-aware private LTE/5G network and also integrate it with public LTE.
We have developed multiple use applications. For example, we have developed context-aware IoT system on campus for population estimation to slow the spread of COVID-19. Our 3C system is a typical application of our proposed context-aware IoT system that has a strong practical value in helping people to monitor the “new lifestyle” when people are gradually returning to the office. Besides maintaining the 200 sensors and 30 base stations deployed in the classrooms, libraries, and cafeterias on four campuses in the University of Tokyo, we have also deployed 30 sensors and 10 base stations to monitor the number of climbers at various inspection points on Mount Fuji area in real time to protect the safety of climbers. We have also deployed IoT sensors and gateways in Hiroshima to monitor the ocean environment to support the local fisheries industry.
