Abstract: In this talk, we present techniques to enable green communications in future generation of wireless systems that will rely on cooperation and cognition to meet increasing demand of high data rate. So far, achieving high data rate has been the primary focus of research in cooperative and CR systems, without much consideration of energy efficiency. However, many of these techniques significantly increase system complexity and energy consumption. Escalating energy costs and environmental concerns have already created an urgent need for more energy-efficient "green" wireless communications. Therefore, we need to design energy-efficient solutions for cooperative and cognitive networks, which will potentially drive the future generation of wireless communication. We focus on several important topics that are crucial towards reducing the energy consumption of the cognitive and cooperative networks. These topics include efficient base station redesign, heterogeneous network deployment, green communications via cognitive radio, cooperative relays to deliver green communications, and energy efficient cognitive cooperative networks.

Speaker Biography: Vijay Bhargava, an IEEE Volunteer for three decades, is Professor in the Department of Electrical and Computer Engineering at the University of British Columbia in Vancouver, where he served as Department Head during 2003-2008. Previously he was with the University of Victoria (1984-2003) and Concordia University (1976-84). He received his Ph.D. from Queen's University in 1974. He is a fellow of the IEEE, the Royal Society of Canada, the Canadian Academy of Engineering and the Engineering Institute of Canada. Vijay has served on the Board of Governors of the IEEE Information Theory Society and the IEEE Communications Society. He has held important positions in these societies and has organized conferences such as ISIT'83, ISIT'95, ICC'99 and VTC 2002 Fall. He played a major role in the creation of the IEEE Transactions on Wireless Communications, and served as its editor-in-chief during 2007, 2008 and 2009. He is a past President of the IEEE Information Theory Society and has been elected to serve as IEEE Communications Society President-Elect during 2011 and as President during 2012 and 2013.
