| Research Activities |
We study systems and strategy issues related to ubiquitous networks and computing, next generation Internet, mobile Internet, distributed computing, and photonic Internet. Our goal is to define network architectures, protocols, applications, and systems of future information utility for all levels of network design, ranging from photonic Internet to network-oriented applications and services.
Vision - 3C Everywhere and Physical Interaction
We envision "3C everywhere" and "physical interaction" as central themes in the future network environment. "3C Everywhere" consists of "Computing everywhere", meaning every object has embedded processors, "content everywhere", meaning files, data and applications are ubiquitous within networks, and "connectivity everywhere", meaning all objects are permanently connected to networks via heterogeneous links. "Physical interaction" connects the physical world to pervasive networks of sensor-rich, embedded computation. We seek to develop new methodologies and information infrastructure that will facilitate the exchange of information between devices and people within a 3C-everywhere context and will result in the physically connected world becoming increasingly more convenient.
MLAB Style
Two major MLAB events are the departmental open house in spring, and the MLAB forum in winter. The MLAB forum provides our collaborators with the opportunities to access our research findings and to facilitate open dialogue with each other. The number of participants in the MLAB forum in 2006 was approximately 150.
For your interest, the following is a part of a list that I showed to newcomers at the first lab meeting in April: "Say something vivaciously and freely", "Be confident", "Have your own opinion", "Carry out your word", "Enjoy your friends", "Accept criticism", "Have a broad outlook", "Plan events such as parties, camps, sports, hiking ...", "Avoid `research for research's sake'", "Avoid writing`junk' papers", "Find a research topic that will open up new area" ...
Research Topics
An enormous number of network interfaces will surround us in the future networked environment. In such an environment, networks will be required to support enormous "heterogeneity" with respect to links, resources, and services. At the same time, since user needs will also take on a variety of forms, networks need to provide a variety of services without placing too much of a load on users. We are engaged in research and development to build new network architectures, and to demonstrate the innovative application prototypes.
Specifically, the research groups include:
- New Generation Internet,
- Sensor Networks,
- Context-aware Computing,
- Mobile Internet, and
- Photonic Internet.
All are engaged in activities to influence all levels of network design at a number of ubiquitous network testbeds including the Komaba Campus, Hongo Campus, Akihabara Daibiru Building, and the Yokosuka Research Park Venture Building.
In addition, we are also involved in several joint research projects with corporate and foreign researchers for realizing new generation networks.

| Future Plan |
When we talk about future networks, we talk of a world where a considerable number of processors, in the form of our daily life home appliances, watches, indoor sensors, lights, and even furniture will be connected. If everything is connected, a new world consisting of totally different networking concepts will be possible. From this perspective, we aim to clarify what the future network society should look like and what fundamental technologies will be required to construct it. By taking advantage of the unique merits of the Graduate School of Frontier Sciences, where researchers from various disciplines conduct research together, we plan to build the next generation network architecture and applications through the collaboration and involvement of various contributors.

| Messages to Students |
It would be wonderful if we could achieve spiritual enlightenment through our labor and pleasure. It may also be good to lie down once in a while as it has been said that our perspective can change depending on whether we are standing upright and when we are horizontal.
We should learn from the fact that nobody dreamed that the Internet and cell phones would become this popular as recently as several years ago. This can be summarized by saying that we need to be flexible thinking in the field of networking research. Flexible and "young" thinking is necessary in order to develop innovative networking technologies and applications. Making a Vision Reality!
