A Message from Technical Program Chairs

On behalf of the technical program committee (TPC), we would like to welcome you to CrownCom 2007 -- the International Conference on Cognitive Radio Oriented Wireless Networks and Communications! This is the second year that this conference is being held, and we are very excited about the technical program and what it has to offer to the cognitive radio research community.

The technical program includes 78 high quality papers covering a broad range of important and timely issues in this area. These papers have been grouped together into 18 technical sessions: a special session on the fundamental theory of dynamic spectrum access organized by Dr. Ananthram Swami (US Army Research Labs) and Dr. Qing Zhao (University of California Davis), three sessions on spectrum sensing, two sessions on resource allocation, two sessions on cognitive radio design, two sessions on physical layer issues, three work-in-progress sessions, and one session each on interference, MAC, channel assignment and MAC, platforms and testbeds, and application, security, and policy

Of these 78 papers, 11 are invited papers; 53 are full papers accepted from open call for paper submissions (a total of 88 submissions); and 14 are work-in-progress short papers. For each paper, we have provided at least three independent reviews, most of which were offered by members of the TPC. The acceptance rate for full papers is 60%.

We have two recipients for this year’s Best Student Paper Award. They are Juan-Andres Bazerque and Georgios B. Giannakis of Univ. of Minnesota for their paper entitled "Distributed Scheduling and Resource Allocation for Cognitive OFDMA Radios" and Fan Wang, Marwan Krunz, and Shuguang Cui of Univ. of Arizona for their paper entitled "Price-Based Spectrum Management in Cognitive Radio Networks". These two papers have been chosen by the TPC Chairs based on their originality, depth, and potential impact. Moreover, some selected papers from this conference will be recommended for publication in the ACM/Springer Mobile Networks and Applications (MONET) Journal Special Issue on "Cognitive Radio Oriented Wireless Networks and Communications" to appear in 2008.

The final technical program is the result of the dedication and hard work of many people. We would like to sincerely thank all of the 126 TPC members, as well as a few external reviewers, who have greatly contributed to the success of the CrownCom 2007 review process. Special thanks are due to the conference steering committee, Dr. Imrich Chlamtac (Create-Net) and Dr. Honggang Zhang (Create-Net), for their guidance and support, as well as the CrownCom 2007 General Chairs, Dr. Rajarathnam Chandramouli (Stevens Institute of Technology) and Dr. Frederick Martin (Motorola USA) for their leadership. Finally, we are indebted to the other members of the conference organizing committee, especially Dr. R. N. Uma (North Carolina Central University), Mr. Wenjing Wang (University of Central Florida), and Ms. Kitti H. Kovacs (ICST) for their help that made our job much easier and enjoyable.

We hope that CrownCom 2007 will be a very rewarding and positive experience for everyone. Moreover, we hope you find time to enjoy all the attractions and activities that Orlando, Florida and its beautiful surrounding areas have to offer. Wish all of you a productive and enjoyable conference.

Biography

Prof. Thomas Hou received the B.E. degree from the City College of New York in 1991, the M.S. degree from Columbia University in 1993, and the Ph.D. degree from Polytechnic University, Brooklyn, New York, in 1998, all in Electrical Engineering.

Since August 2002, he has been with Virginia Tech, the Bradley Department of Electrical and Computer Engineering, Blacksburg, VA, where he is now an Associate Professor. His current research interests are radio resource (spectrum) management and networking for software-defined radio wireless networks, optimization and algorithm design for wireless ad hoc and sensor networks, and video communications over dynamic ad hoc networks. From 1997 to 2002, Dr. Hou was a Researcher at Fujitsu Laboratories of America, Sunnyvale, CA, where he worked on scalable architectures, protocols, and implementations for differentiated services Internet; service overlay networking; video streaming; network bandwidth allocation policies and distributed flow control algorithms.

Prof. Hou is a recipient of an Office of Naval Research (ONR) Young Investigator Award (2003) and a National Science Foundation (NSF) CAREER Award (2004) for his research on algorithm design and optimizations for wireless ad hoc and sensor networks. He has published extensively in leading journals and top tier conferences and received several best paper awards from IEEE for his publications. He holds two U.S patents and has three more pending.

Prof. Hou is active in professional services and is currently serving as an Editor of IEEE Transactions on Wireless Communications, ACM/Springer Wireless Networks (WINET), and Elsevier Ad Hoc Networks Journal. He was the Founding Chair of the First IEEE Workshop on Networking Technologies for Software Defined Radio Networks, September 25, 2006, Reston, VA. Prof. Hou will serve as Co-Chair of Technical Program Committee (TPC) of IEEE INFOCOM 2009, to be held in Rio de Janeiro, Brazil.
