Summer Happenings

A better-late-than-never update from Summer 2010.

Several members of the group visited other places this summer:

  • Uchenna Anyanwu spent the summer working with Luiz DaSilva and Linda Doyle at CTVR in Trinity College Dublin, Ireland.  He worked on the implementation of medium access control in the IRIS software radio platform.
  • Amr Hilal had a summer internship with Google.
  • Ryan Irwin had a summer internship with Raytheon/BBN Technologies.
  • Yongsheng Shi had a summer internship with Qualcomm.

In addition, we have several visitors to our group in Blacksburg this summer:

And, we have one new group member that joined this summer:

  • Frank Bieberly  has been working on heterogeneous computing in GNU Radio, using the DSP on a Beagle Board.  Frank earned his B.S. from Northwestern University and then spent five years in the US Navy.

DySPAN Tutorial

On April 6, Dr. MacKenzie and Dr. Luiz DaSilva will give a half-day tutorial entitled “Game Theory for Cognitive Radio Networks” at the IEEE Symposium on New Frontiers in Dynamic Spectrum Access Networks (DySPAN) in Singapore. Registration for the conference and the tutorials is now open.

If you can’t make it to Singapore, a similar tutorial is planned for the Wireless @ Virginia Tech Symposium & Summer School in June.

Game theory is a field of applied mathematics that describes and analyzes interactive decisions. Its ability to model individual, independent decision makers whose actions potentially affect others makes game theory particularly suitable to studying the environments in which cognitive radios operate. In this half-day tutorial, we will describe some of the main applications of game theory to cognitive networks. These include: models of cooperation and coexistence among cognitive radios and between cognitive radios and legacy users; spectrum auctions and other economic models; and the modeling of partial or incomplete information in decision making.

We will address the following topics:

  • Motivation: a case for game theory in cognitive radio research
  • Game theory basics
  • Power control and interference games
  • Distributed channel assignment and topology control games
  • Cooperative models of dynamic spectrum access
  • Real time spectrum markets
  • Mechanism design: truth telling and incentive compatibility

    Welcome to New Students

    Our research group welcomes two new Ph.D. students, Uchenna Anyanwu and Mohammed Baidas, beginning this month.

    Uchenna Anyanwu received a B.S. in Computer Engineering from San Jose State University last May, and spent the last seven months workingfor Intel. He joins us as a Ph.D. student and Bradley Fellow in Computer Engineering. His research will explore wireless communication and reconfigurable devices, to develop inexpensive, flexible software defined radios that are capable of high-speed, random access data networking.

    Mohammed W. Baidas received the B.Eng (first class honours) degree in communication systems engineering from the University of Manchester, UK, the M.Sc. degree with distinction in wireless communications engineering from the University of Leeds, UK, and also the M.S. degree in electrical engineering from the University of Maryland, College Park in 2005, 2006 and 2009, respectively. He joins us to pursue his Ph.D.   His research interests include resource allocation and management in cognitive radio systems, game theory, and cooperative communications and networking. Mohammed holds a full scholarship from Kuwait University.
