【Job category of graduates】
Information and communication industry, manufacturing industry (information communication, home appliances, etc.)
IEEE 1394-ATM connection device as SONY TL-100
Due to popularization of personal computers (PC) and realization of broadband connections, networks are everywhere, including our homes. However, most of these technologies originate from office and research environments. Thus, it may be difficult for non-expert users to utilize such solutions in a typical home environment. Our research emphasizes interconnectivity with existing devices and infrastructure in the home and focuses on advances regarding future home networks and devices.
Example of projects:
* JAIST Video LAN
Question: If the video camera becomes digital, can it connect to the digital network as usual? Solution: Introduce and IEEE 1394 and ATM connectivity device (practical for academic institutions).
Achievement: Commercialization of connected devices is achieved through collaborative research with companies. It is widely used at universities. Received Industry Contribution Award at Japan Gigabit Network.
* Architecture of heterogeneous video network interconnectivity.
Question: Why computers, broadcasting systems, and communication networks cannot interoperate even though they are all used to stream video and audio?
Solution: Introduce an interconnected architecture, based on the most important basic functions.
Achievement: Adopted for industry-university cooperation project of communication and broadcasting organization.
* Home network with legacy devices
Question: In order to live a convenient life with networked home appliances; do I have to replace all household appliances?
Solution: Create a system in which legacy devices that you bought ten years ago can also connect to the home network.
Achievement: Developed a system with which legacy devices can connect to networks utilizing existing communication paths (power line, antenna wire), wireless networks, based on modeling infrared control and finite states of each electric appliance. Currently, it is under consideration for practical application with enterprises.
Collaboration with outside organizations:
Professor Tan is a steering committee of ubiquitous and information appliance related academic societies, such as IPSJ IAC, IPSJ UBI, IPSJ MBL, IEICE NGN, IEICE URON, etc.
He is a leader of industry forums, such as Smart IoT Acceleration Forum Technical and Standardization subcommittee, and DC Alliance. In addition, he has deep connection with industry, because he compiled technical commentaries of standards establishment and technologies for standardization bodies, such as Telecommunication Technology Committee and Ministry of Internal Affairs and Communications.
- Development of various technologies of cloud type home network system and international standardization (ITU-T J.190, Y.2070, etc.)
- Development of smart house simulator and smart community simulator and its open source
- Development and commercialization of audio / visual network connection device using home appliances as terminals
Two-story experimental house × 1
Prefabricated experiment house × 2
ECHONET Lite development environment
Large scale simulation with cluster system

Our aim is to educate world-class engineers who are ready to lead and can take an idea from its concept stage and turn it into reality. Students will have a chance to improve their knowledge and sharpen their engineering skills by actively participating in theoretical and technical discussions regarding fundamental knowledge such as software engineering and computer networking as well as by solving real-world problems through hands-on collaborative research with companies and participation in industry forums. Just like painting on a white canvas, we put strong emphasis on cultivating the ability to grasp the true form of things, and being able to understand architectural details and to design appropriate implementation solutions.
