Seminário "Informática em Ciências", por Vijay Bhargava (University of British Columbia, Canada).

Abstract: By the year 2020, Fifth Generation (5G) wireless networks are expected to provide anew paradigm over the existing networks. The targets for 5G include: 10,000 times increase in traffic data, 10-100 times more devices, low latency in the order of 1msec, more uniform coverage providing a minimum of 1Gbps for every user, flexible operation in different radio access technologies, reliable end-to-end performance, low cost and energy efficient design. As in 5G networks millions more base stations are expected to serve the users, one of the significant design considerations is achieving better performance with smart energy consumption. In this presentation, firstly we present an overview of the existing scenario on energy consumption in base stations. Next, we introduce energy-efficient research approaches for different types of system and network architectures of 5G. We present energy-efficient designs for multi-tier heterogeneous networks including cell association, resource allocation and wireless backhaul bandwidth allocation. Then we present an overview of device-to-device communication systems. The talk concludes with an overview of the application of these technologies to Automation with emphasis on Internet of Things (IOT, sometimes Internet of Everything) to automation and the challenge presented by 50 billion “connected” devices by 2020.

He is a 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), Concordia University (1976-1984), the University of Waterloo (1976) and the Indian Institute of Science (1974-1975). He has held visiting appointments at Ecole Polytechnique de Montréal, NTT Research Lab, Tokyo Institute of Technology, the University of Indonesia, the Hong Kong University of Science and Technology, and Tohoku University. He is an Honourary Professor at UESTC, Chengdu and a Gandhi Distinguished Professor at IIT Bombay. For the academic year 2015-2016, he is on sabbatical leave at the Friedrich Alexander University (FAU), Erlangen, Germany. He is in the Institute for Scientific Information (ISI) Highly Cited list. 

Vijay served as the Founder and President of "Binary Communications Inc." (1983-2000). He is a co-author (with D. Haccoun, R. Matyas and P. Nuspl) of "Digital Communications by Satellite" (New York: Wiley: 1981) which was translated in Chinese and Japanese. He is a co-editor (with S. Wicker) of "Reed Solomon Codes and their Applications" (IEEE Press: 1994), a co-editor (with H.V. Poor, V. Tarokh and S. Yoon) of "Communications, Information and Network Security" (Kluwer: 2003) a co-editor (with E. Hossain) of "Cognitive Wireless Communication Networks" (Springer: 2007), a co-editor (with E. Hossain and D.I Kim) of “Cooperative Wireless Communications Networks”, (Cambridge University Press: 2011) and a co-editor (with E. Hossain and G. Fettweis) of “Green Radio Communications Networks” (Cambridge University Press 2012).

Vijay is a Fellow of the IEEE, The Royal Society of Canada, The Canadian Academy of Engineering and the Engineering Institute of Canada. He is a Foreign Fellow of the National Academy of Engineering (India) and has served as a Distinguished Visiting Fellow of the Royal Academy of Engineering (U.K.). He has received awards for his teaching, research and service to the IEEE. The latest awards are the Killam Prize in Engineering and the Humboldt Research Prize.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. He has served as an Associate Editor of the IEEE Transactions on Communications. He played a major role in the creation of the IEEE Communications and Networking Conference (WCNC) and IEEE Transactions on Wireless Communications, for which he served as the editor-in-chief (2007-2009). He is a past President of the IEEE Information Theory Society and a Past President of the IEEE Communications Society.
