Abstract: The presentation of Prof. Niu was divided into four sections. In the first section, Background and Motivation, Prof. Niu introduced the history of communication, the motivation of GREEN communication and Green activities all over the world. In the second section, Paradigm Shifts towards GREEN, Prof. Niu claimed that green communication should be involved in more high level in paradigm shift. He raised two important questions to help us rethink about relationship between spectral efficiency and energy efficiency in cellular structure. Then, two different paradigm shifts are introduced. One is TANGO, i.e., traffic aware network planning and green operation. The other is CHROUS, collaborative & harmonized open radio ubiquitous system. Two promising technologies called cell zooming and dynamic BS clustering are illustrated to demonstrate the two different shifts in detail. In the third section, Energy-Delay Tradeoff in GREEN, Prof. Niu raised the question on how to tradeoff the energy consumption and delay. It is shown that a big consumption reduction can be realized when considering the queue theory, Shannon capacity formula and the optimal queue condition. Based on this motivation, he extended the conclusion with more practical constraints and applied these simplified models to derive the tradeoff between energy and delay with close-down time and N users¡¯ arrivals. Finally, conclusions are drawn in the fourth section on the basic rules to optimize the resource making the network more energy efficient, two meaningful approaches: TANGO and CHROUS and main findings considering energy ¨Cdelay tradeoff in GREEN.

Biography:
Zhisheng Niu graduated from Northern Jiaotong University (currently Beijing Jiaotong University), Beijing, China, in 1985, and got his M.E. and D.E. degrees from Toyohashi University of Technology, Toyohashi, Japan, in 1989 and 1992, respectively. After spending two years at Fujitsu Laboratories Ltd., Kawasaki, Japan, he joined with Tsinghua University, Beijing, China, in 1994, where he is now a professor at the Department of Electronic Engineering and the deputy dean of the School of Information Science and Technology. His major research interests include queueing theory, traffic engineering, mobile Internet, radio resource management of wireless networks, and green communication and networks.
Dr. Niu has been an active volunteer for various academic societies, including council member of Chinese Institute of Electronics (2006-10), vice chair of the Information and Communication Network Committee of Chinese Institute of Communications (2008-12), Councilor of IEICE-Japan (2009-11), and membership development coordinator of IEEE Region 10 (2009-10). In particular, in IEEE Communication Society, he has been serving as an editor of IEEE Wireless Communication Magazine (2009-12), director of Asia-Pacific Region (2008-09), director for Conference Publications (2010-11), chair of Beijing Chapter (2001-08), and members of Award Committee (2011-13), Emerging Technologies Committee (2010-12), On-line Content Committee (2010-12), and Strategy Planning Committee. He has also been serving as general co-chairs of APCC¡¯09/WiCOM¡¯09, TPC co-chairs of APCC¡¯04/ICC¡¯08/WOCC¡¯10/ICCC¡¯12, panel co-chair of WCNC¡¯10, tutorial co-chairs of VTC¡¯10-fall/Globecom¡¯12, and publicity co-chairs of PIMRC¡¯10/WCNC¡¯02. He was the guest co-editors of the IEEE Wireless Communication Magazine Special Issue on Green Radio Communications and Networks (published on Oct. 2011) and the Communication Networks Special Issue on Green Communication Networks (to be published in 2012).
Prof. Niu received the Best Paper Awards from the 13th and 15th Asia-Pacific Conference on Communication (APCC) in 2007 and 2009, respectively, and Outstanding Young Researcher Award from Natural Science Foundation of China in 2009. He is now the Chief Scientist of the National Fundamental Research Program (so called ¡°973 Project¡±) of China "Fundamental Research on the Energy and Resource Optimized Hyper-Cellular Mobile Communication System" (2012-2016), which is the first national project green communications in China. He is the fellow of IEEE and IEICE, and a distinguished lecturer of IEEE Communication Society (2012-13).
