Seminar: Orchestrating Virtual Wireless Networks from Shared Resource Pools

12:00 AM - 1:00 PM on Friday, October 11, 2013
Location: Whittemore 457; NVC 320

Dr. Luiz DaSilva will be the speaker.

Pressures on mobile network operators to support ever increasing data rates, while keeping costs fairly flat, will require large scale and dynamic sharing of resources among operators, as well as harnessing of spontaneously deployed local area wireless infrastructure. We have recently proposed the concept of Networks without Borders, which allow for the dynamic establishment of virtual networks from a pool of wireless resources, encompassing spectrum, infrastructure, and management and control functionality.

In this talk, we will present our initial models for the sharing of infrastructure and spectrum and its impact on coverage and aggregate capacity. We employ game theory to model the use of carrier aggregation and the ability of mobile network operators to schedule access to each other’s licensed spectrum. On the infrastructure side, we have started to use mobile operator data from Europe to quantify the infrastructure requirements to achieve a given coverage target, treating current base station deployment as a pool of resources from which a virtual network can be architected.

Luiz A. DaSilva is a professor in the Bradley Department of Electrical and Computer Engineering at Virginia Tech. He also holds the Stokes Professorship in Telecommunications in the Department of Electronic and Electrical Engineering at Trinity College Dublin.

His research focuses on distributed and adaptive resource management in wireless networks, and in particular cognitive radio networks, dynamic spectrum access, and the application of game theory to wireless networks. Prof. DaSilva is currently a principal investigator on research projects funded by the National Science Foundation in the United States, the Science Foundation Ireland, and the European Commission under Framework Programme 7. He is a co-principal investigator of CTVR, the Telecommunications Research Centre in Ireland.

He has co-authored two books on wireless communications and in 2006 was named a College of Engineering Faculty Fellow at Virginia Tech.
