Professor MacKenzie was awarded an E.T.S. Walton Visitor Award from the Science Foundation of Ireland for the 2012-2013 academic year. This award will enable him to spend the 2012-2013 academic year on study-research leave from Virginia Tech. During the year, he will be based at CTVR: the telecommunications research centre at Trinity College Dublin. Professor MacKenzie will be working, broadly, on technology and policy solutions for dynamic spectrum sharing in wireless networks and economic models of such solutions. More specifically, he will be studying automated spectrum negotiation between autonomous radio systems.
Congratulations to the graduates from the research group this Spring:
- Mohammed Baidas, Ph.D. Mohammed will be a faculty member at Kuwait University.
- Frank Bieberly, M.S. Frank has accepted a position at MIT Lincoln Laboratories.
- Ryan Irwin, Ph.D. Ryan has accepted a position with Raytheon BBN Technologies.
And we welcome to two new students:
- Varuni Katti Sastry, an M.S. student, joined the group this Spring. She is working on game theoretic models of network sharing between cellular and WiFi network operators. This is part of a collaborative research project with the Centre for Wireless Communications at the University of Oulu, Finland, where Varuni will spend two months this summer.
- Gayathri Ramasubramanian, an M.S. student joined the group this Summer. She will be working on the FINS Framework project.
My goal for the next academic year will be at least one roundup post each semester. But for now, a summer update. I have updated all of the pages on the site (linked from the tabs above) in the last week or so!
Several members of the group are visiting other places this summer:
- Abdallah Abdallah is starting a six-month internship at Intel in Santa Clara, California in July.
- Uchenna Anyanwu is spending another summer working with Luiz DaSilva and Linda Doyle at CTVR in Trinity College Dublin, Ireland. He is work on the implementation of medium access control in the IRIS software radio framework using the new USRP Embedded (E100) hardware.
- Frank Bieberly is working on a summer internship at MIT Lincoln Laboratory.
In addition, we have a couple of undergraduates working with our group in Blacksburg this summer:
- Kevin Burns is a rising Senior in Computer Engineering at Virginia Tech. He is working on an external control interface for the FINS Framework.
- Mark Hutcheson is a rising Junior in Computer Engineering at Virginia Tech. He is working on ICMP and TCP modules for the FINS Framework.
Two new graduate students will join the group in the Fall. More to come!
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:
- David Moura is a Ph.D. student at the Military Institute of Engineering (Instituto Militar de Engenharia) in Brazil and was a visiting scholar with us for the summer. He worked on game theoretic modeling of self coexistence in wireless systems.
- Alex Barteau is an undergraduate student at Bucknell University who participated in a summer research experience with us. He worked on UDP and ICMP modules for the FINS Framework.
- Rado Petrik is an undergraduate student at Copenhagen University College of Engineering (Ingeniørhøjskolen i København) in Denmark and was an exchange student at Virginia Tech last semester. He also participated in a summer research experience with us, working on IP and TCP modules for the FINS Framework.
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.
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
Update: Slides are now available here [PDF, 7.3 MB].
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.
