Séminaire dirigé par Professeur Vijay BHARGAVA






Sup'Com organise un séminaire intitulé « Evolving Fifth Generation Cellular Networks: An Energy-Efficient Perspective », dirigé par le Professeur Vijay BHARGAVA, May20th, 2015 at 2:00 pm (AMPHI II)








Professor in the Department of Electrical and Computer Engineering at the University of British Columbia in Vancouver



Vijay Bhargava was born in Beawar, India in 1948. He came to Canada in 1966 and obtained BASc, MASc and PhD degrees from Queen’s University at Kingston in 1970, 1972 and 1974 respectively. Currently 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. He is in the Institute for Scientific Information (ISI) Highly Cited list.




By the year 2020, Fifth Generation (5G) wireless networks are expected to provide a new paradigm over the existing cellular 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 discuss secure transmission schemes of massive MIMO systems. Next we present an overview of device-to-device communication systems. Finally, we introduce energy harvesting technology as a key enabling technique for energy-efficient networks. We discuss its capability to reduce energy consumption in base stations, and its potential to alleviate limited battery life constraint in low power wireless devices. We conclude the presentation with a discussion of different energy harvesting techniques and the challenges associated with them.
