 Research Interests and Some Personal Info. |
Dr. Tanaka is a pioneer in the field of multicast telecommunication. Though
there were many theories and technologies concerning 1:1 telecommunication,
there were few theories and few technologies concerning multicast telecommunication
until he started his studies 20 years ago. All of his research on multicast
telecommunication has been totally new, and his book about multicast telecommunication
was the first of its kind in the world. Now, multicast telecommunication
is regarded as a key technology of multimedia, and has become widely studied.
Recently, he has also become interested in another field: pricing. Nowadays,
accounting is done by computer, and, therefore, any kind of tariff can
be used. Dr. Tanaka is researching methods to allot bandwidth through auction,
and methods to set tariffs adaptive to network congestion, etc. This field
should prove to be important in the near future.
Dr. Tanaka has been a specialist member of the Telecommunications Consultative
Committee of the Ministry of Public Management, Home Affairs, Posts and
Telecommunications, an editor-in-chief of the International Telecommunication
Union Association of Japan, a chairman of IEICE Technical Committee on
Network System, a chairman of IEICE Technical Committee on Telecommunication
Management, an editor-in-chief of IEICE Transactions on Communications,
and a councilor of IEICE Tokyo Section. He has also served many other posts
in committees, conferences, societies, and groups.
Dr. Tanaka received the IEEE Outstanding Student Award in 1977, the Niwa
Memorial Prize in 1980, the IEICE Achievements Award in 1980, the Okawa
Publication Prize in 1994, the TAF Telecom System Technology Award in 1995,
the IEICE Information Network Research Award in 1996 and in 2001, the IEICE
Communications Society Activity Testimonials in 1997 and in 1998, the IEICE
Switching System Research Award in 2001. He is a Fellow of IEICE and a
Senior Member of IEEE.

Appointments and Professional Experience |
Dr. Tanaka received his B.E., M.E., and Ph.D. degrees in electrical engineering
from the University of Tokyo, Tokyo, Japan, in 1974, 1976, and 1979, respectively.
He worked at the Department of Electrical Engineering, the University of
Tokyo, in 1979, and has been teaching and researching in the fields of
telecommunication networks, switching systems, and network security ever
since. He was a guest professor at the Department of Communication Systems,
Lund Institute of Technology, Sweden, from 1986 to 1987. He was also a
visiting researcher at the Institute for Posts and Telecommunications Policy
from 1988 to 1991, and at the Institute for Monetary and Economic Studies,
Bank of Japan, from 1994 to 1996. Since 1996, he has been a professor at
Waseda University.

Project Summary |
We will focus on telecommunication networks and switching systems. Conventional
networks are mainly occupied by realtime unicast traffic; however, it is
expected that multicast traffic and non-realtime contents delivery traffic
will occupy the networks of the future. These new types of telecommunication
require an evolution of network configuration, control systems, switching
systems, and pricing. In this study, we will research such topics as network
topology, routing, contents buffering and delivery control, switching networks,
and pricing control. We will also study fundamental theories, such as teletraffic
theory and network optimization method.
