Guest lecture by Professor Ekram Hossain on 31 AugProfessor Ekram Hossain (Department of Electrical and Computer Engineering at University of Manitoba, Winnipeg, Canada) will give a guest lecture titled “Virtualization of 5G Cellular Networks as a Hierarchical Combinatorial Auction” on the TUT campus on 31 August 2015.
The lecture will take place in room TB222 in the Tietotalo building (address: Korkeakoulunkatu 1, Tampere). The lecture will begin at 10:00.
Virtualization has been seen as one of the main evolution trends in the forthcoming fifth generation (5G) cellular networks, which enables the decoupling of infrastructure from the services it provides. In this case, the roles of infrastructure providers (InPs) and mobile virtual network operators (MVNOs) can be logically separated and the resources (e.g., channels, power, and antennas) of a base station owned by an InP can be transparently shared by multiple MVNOs, while each MVNO virtually owns the entire base station. Naturally, the issue of resource allocation arises. In particular, the InP is required to abstract the physical resources into isolated slices for each MVNO who then allocates the resources within the slice to its subscribed users. In this talk, I will address this two-level hierarchical resource allocation problem while satisfying the requirements of efficient resource allocation, strict inter-slice isolation, and the ability of intra-slice customization. To this end, I will present a hierarchical combinatorial auction mechanism, based on which a truthful and sub-efficient resource allocation framework is designed.
Ekram Hossain (IEEE Fellow) is a Professor in the Department of Electrical and Computer Engineering at University of Manitoba, Winnipeg, Canada, where he leads the Wireless Communications, Networks, and Services (WiCONS) research group (http://home.cc.umanitoba.ca/~hossaina/wicons/index.html). He received his Ph.D. in Electrical Engineering from University of Victoria, Canada, in 2001. Dr. Hossain's current research interests include design, analysis, and optimization of wireless/mobile communication networks. He was elevated to an IEEE Fellow "for contributions to spectrum management and resource allocation in cognitive and cellular radio networks". Currently, he serves as the Editor-in-Chief for the IEEE Communications Surveys and Tutorials and an Editor for IEEE Wireless Communications. Also, he is a member of the IEEE Press Editorial Board. Previously, he served as the Area Editor for the IEEE Transactions on Wireless Communications in the area of “Resource Management and Multiple Access'' from 2009-2011, an Editor for the IEEE Transactions on Mobile Computing from 2007-2012, and an Editor for the IEEE Journal on Selected Areas in Communications - Cognitive Radio Series from 2011-2014. He has won several research awards including the University of Manitoba Merit Award in 2010 and 2014 for Research and Scholarly Activities, the 2011 IEEE Communications Society Fred Ellersick Prize Paper Award, and the IEEE Wireless Communications and Networking Conference 2012 (WCNC'12) Best Paper Award. Dr. Hossain is a Distinguished Lecturer of the IEEE Communications Society (2012-2015).
