I am involved in the research and development of information and communication technology, mainly the communication network technologies. My current research interests include the following:
- 5G and beyond network architectures
- Software-defined networking (SDN)
- Network function virtualization (NFV)
- Information-centric networking (ICN)
- Internet of things (IoT)
- Cyber-physical system (CPS)
- Machine learning
- Artificial intelligence
- Automation of network control and management
- Network resource management
- Cyber security and privacy
- Society 5.0
I was a member of the AKARI Architecture Design Project for New Generation Network or Future Internet during 2006-2010 in Japan. In this project, I designed and implemented the HIMALIS (Heterogeneity Inclusion and Mobility Adaptation through Locator ID Separation) network architecture.
I was involved in the design and development of an IoT directory service (IoT-DS) system with distributed trackable cache servers in the network so that it can store a huge number of records of IoT devices (i.e., control information of IoT devices) and provide very quick lookup of the records. It has been envisioned as a crucial component for the realization new ICT services such as automated driving, smart metering, and realtime health monitoring.
My recent work is focused on the design and development of AI-based network control automation technologies, which can be applied to 5G and beyond networks. On this topic, I am involved in a Japan’s national project involving research institutes, telecom operators and equipment manufactures.
I have been involved in International Telecommunication Union (ITU) since 2008 for the standardization of Next Generation Network, Future Network, and IMT-2020 or 5G network architecture and technologies. I have been a Rapporteur of ITU-T Study Group 13 since 2014. I have contributed technologies to many ITU-T standards.
I have been engaged in teaching and supervising of graduate students (M.S. and Ph.D.) since 2013 as an Associate Professor at University of Electro-Communications (UEC), Tokyo. I have taught “Advanced Network Architecture” course and supervised the research work of six M.S. and two Ph.D. students. I have also co-supervised graduation theses of many other M.S. and Ph.D. students of UEC and other universities in Japan and abroad. To share my knowledge of research, development and standardization of advanced network technologies, I do frequently deliver guest lectures at several universities in Japan.
