Towards Sustainable Information Society – Green and Never Die Networks

In science and technology of the 21st century, how to face global environmental change such as (1) global warming and (2) natural disaster has come into question. In this talk, regarding (1) global warming, we first explain problems of modern information societies based on the rationality which consists of high efficiency, cost effective and high function. And then, we discuss solutions to overcome these problems such as environmental contamination, global warming, and natural disaster towards the creation of a sustainable information society. We have promoted 2 Green research projects on 1) Energy Saving for Network Management of Information Communication Systems, and 2) its demonstration experiment in a wide-area distributed community, Kurihara City in Japan. Regarding (2) natural disaster, we first introduce my experiences of two big earthquakes, 1) Miyagi earthquake in 1978 and 2) Great East Japan Earthquake in 2011[1]. Based on these experiences we proposed a concept of Never Die Networks which has following three features; 1) Real-time services, 2) Massive multiusers and 3) Short-time services. I am now heading a three years research project on Never Die Networks supported by JSPS, Grant-in-Aid for Scientific Research, Kiban (A). The outline of this project will be briefly explained in my talk.
