TITLE
Cognitive Radio for Green Communications and Green Spectrum
ABSTRACT
Nowadays, the whole world of telecommunications and information communities is facing a more and more serious challenge, namely on one side the transmitted multimedia-rich data are exploding at an astonishing speed and on the other side the total energy consumption by the communication and networking devices and the relevant global CO2 emission are terribly increasing.
Gratifyingly, the emerging Cognitive Radio (CR) system and technology are potentially capable of contributing to solve the abovementioned problem for realizing "Green Communications". Basically, Cognitive Radio is characterized of an adaptive, multi-dimensionally aware, autonomous radio system empowered by advanced intelligent functionality, which interacts with its operating environment and learns from its experiences to reason, plan, and decide future actions to meet various needs. This approach can lead to a significant increase in radio resource (spectrum) efficiency, networking efficiency as well as energy efficiency. Within this speech, a number of CR-enabled key advantages will be addressed in detail, including energy-efficient network architecture & protocols, energy-efficient CR transmission techniques (e.g., reduced transmission power & reduced radiation), cross-layer optimization methods, and opportunistic spectrum sharing without causing harmful interference pollution (i.e. Green Spectrum).
BIOGRAPHY
Dr. Honggang Zhang is a Full Professor at the Department of Information Science and Electronic Engineering, Zhejiang University, China.
Dr. Honggang Zhang received the Ph.D. degree in Electrical Engineering from Kagoshima University, Japan, in 1999. From October 1999 to March 2002, he was with the Shin-Kawasaki Research Center, Telecommunications Advancement Organization (TAO) of Japan, as a TAO Research Fellow. From April 2002 to November 2002, he joined the TOYOTA IT Center, where he performed research and development on software-defined radio (SDR) with applications to Intelligent Transport Systems (ITS). From December 2002 to August 2004, he has been with the UWB (Ultra-Wideband) Research Consortium, Communications Research Laboratory (CRL) and National Institute of Information and Communications Technology (NICT) of Japan, where his R&D responsibilities were focused on UWB wireless communications, IEEE 802.15 WPAN standardizations, Wireless 1394 and "1394-Over-UWB" smart home networks. He was the founding member of UWB Forum and the principle author and contributor for proposing DS-UWB in the IEEE 802.15 WPAN standardization task group, for which he initiated the "Soft-Spectrum Adaptation (SSA)" technique and contributed to its worldwide developments. From September 2004 to February 2008, he has been with CREATE-NET (http://www.create-net.org/), where led its wireless teams in exploring Cognitive Radio (CR) and its integration with Ultra-Wideband technologies for open-spectrum wireless communications and networks evolution while participated a number of European FP6 & FP7 projects (EUWB, PULSERS 2, etc.).
Dr. Honggang Zhang is taking a leading role in the Technical Committee on Cognitive Networks (TCCN) of the IEEE Communications Society (ComSoc) as Vice-Chair. He is the Co-Chair of IEEE Globecom 2008 General Symposium on the Selected Areas in Communications (GS-SAC). He is the founding Technical Program Committee (TPC) Co-Chair of CrownCom 2006 (International Conference on Cognitive Radio Oriented Wireless Networks and Communications 2006) as well as the Steering Committee Member of CrownCom 2006-2008.
