Our laboratory will focus on merging the internet and wireless networks by conducting technical and society-oriented research, development, and proposals for new applications and business models using wireless networks.

Our agenda: 1) validation and diffusion of mobile communications technology and network design, 2) authentication technology for open platforms, 3) realization of non-preemptive handover technology between foreign wireless networks, 4) establishment and governance of laws, systems, rules, and radio frequency assignment rules oriented to open wireless platforms, and 5) new communication services with applications to disaster and emergency situations.

SOI (School on the Internet) Working Group in WIDE Project was started in September 1997, considering the change of role in the Internet. Our goal is "to provide higher education and opportunity for all the people in the world who have the will to study using Internet based technologies, eliminating traditional limitations." In October of the same year, we have started WIDE University "School of Internet" as a testbed of our new concept. Since then, we have been doing researches such as education based on the Internet, development of the university environment, and research about the education system of the new age.

SOI ASIA Project is distance education project using satellite Internet in Asia, which proposes a new educational methodology for universities in Japan as well as educational institutions abroad. We have been conducting classes and organizing events in many fields, such as information technology, computer science, marine science, and disaster management. As of September 2007, this project has 27 universities and research institutes partners in 13 countries in Asia, and has deployed receive-only satellite earth stations at each partner site to share the distribution of live lectures from Japan as well as archived lectures.

Now, the Intelligent Transport Systems (ITS) attracts many people's concern. ITS is the general term of the field which considers a car, a man, and a road as o ne system, and builds an efficient road traffic system. Various things, such as Car Navigation, Vehicle Information and Communication System (VICS), Electronic Toll Collection System (ETC) are positioned in ITS.

ITS can be divided into 2 fields. One is greatly advanced by government initiative, and another is advanced by private sector initiative. About the things that need plant-and-equipment investment like ETC, Advanced Cruise-Assist Highway System (AHS) are being progressed by government initiative. And the things that are unnecessary with plant-and-equipment investment like Car Navigation are being progressed by private sector initiative.

As the social computerization progressed, the strong needs from the information industry to ITS came out. The demand of "wanting to use the car's information by the computer network" could be a natural thing from the flow of the present society. We have proposed the InternetCAR as a system for satisfying these needs.

The Internet car is a framework for treating a car as a node on the Internet. We have a viewpoint from the Internet information system in order to carry out how to connect a car to the Internet, how to acquire the car's information via the Internet, what mechanism is required to exchange the information between the cars and so on. In this ITS field, we can provide some business chance to the people who have difficulties to enter into the information industry venture. Thereby, the Internet car may serve as a growth catalyst of a private sector ITS.

Our desire is to build a more wonderful automobile information environment by the spread of the InternetCARs.

AI3 project conducts research and development activity in networking technologies and human resource development using satellite links as data link of the Internet. This project operates a wide-area testbed network connecting 29 research and academic organizations in 13 Asian countries.

Our research focuses are satellite data links, IPv6, multicasting, routing and network operation. We evaluate our research output using our operational satellite Internet environment.

Our network provides Internet connectivity to developing regions, and conducts distance education programs in Asia. High-speed networks using fiber optic cables, which is now spreading in Asian regions, are also our interest in terms of how to use it together with satellite links as broadcast media.

People in AutoID are working for "Internet of things" which is a combination of Internet and automatic identification technologies such as RFID and bar-code.

Internet of things requires advanced technologies in the wireless, software and networking arena. Studies on the social acceptance and business model are also essential for large scale adoption. Researchers in AutoID are working in the dedicated reasearch fields yet collaborating on contracted researches, national and international projects. Undergrads and graudates students are welcomed to participate in such joint researches.

AutoID has a league of sister laboratoies, Auto-ID Laboratories, in US, UK, Switzerland, Australia, China and Korea. We collaboratively work in international standardizations, academic conference organizations and regional workshops related to Internet of things.

WIDE and CNRS has launched collaboration of mobility and measurement topics. This project is supported by French and Japanese government and will continue for two years. We exchange researcher, research information, technical results between two countries.

The goal of mobility project is re-architecturing the Internet using the renowned expertise in IPv6 and Mobility and Next Generation Internet in our scientific communities. This new vision of the Internet would based on the assumption that most or all communicating devices would be communicating though a wireless medium and where all its composing parts (protocols, intermediate devices and etc.) would be reengineered so that they fit well in. Work on the project would be done in joint efforts of our two countries and would lead to a proof of concept demonstration upon.See Mobility as detail.

There have been considerable advances in Internet measurement and modeling in the last decade. However, it turned out to be extremely difficult to understand the constantly changing behavior of the global Internet.
Among other things, understanding the behavior of emerging applications such gaming, peer-to-peer applications and networked appliances is critical to predicting the future Internet. Another important area is to effectively detect new types of security threats since attack techniques are rapidly evolving.
Although emerging applications and threats are considerably different in nature, there exit common factors in terms of measurement and modeling. In order to understand seemingly intractable behavior of emerging applications and threats, it is essential to combine practical skills and knowledge with solid theoretical methodologies. See Measurement as detail.
