Abstract:'Cognitive radio' based on dynamic spectrum access is an emerging technique
to improve the utilization of radio frequency spectrum in wireless networks.
Built upon software-defined radio, it combines wireless communications and
mobile networking with signal processing, machine learning, optimization,
and microeconomic models. In this talk, an introduction to the dynamic
spectrum access-based cognitive radio networks will be provided.
Specifically, the basic concepts behind ?cognitive radio? technology, basic
functionalities in a cognitive radio transceiver for dynamic spectrum
access, and different spectrum sharing models will be described. The key
technical challenges related to spectrum sensing, dynamic spectrum
sharing/medium access control, and spectrum pricing in these networks will
be presented.

ISBN: 978-0-387-09776-3), and a co-author of the book Introduction to
Network Simulator NS2 (Springer, 2008, ISBN: 978-0-387-71759-3). Dr. Hossain
serves as an Editor for the IEEE Transactions on Mobile Computing, the IEEE
Transactions on Wireless Communications}, the IEEE Transactions on Vehicular
Technology, IEEE Wireless Communications, and several other international
journals. He served as a guest editor for the special issues of IEEE
Communications Magazine (Cross-Layer Protocol Engineering for Wireless
Mobile Networks) and IEEE Wireless Communications (Radio Resource Management
and Protocol Engineering for IEEE 802.16). He served as a technical program
co-chair for the IEEE Globecom'07 and IEEE WCNC'08. Dr. Hossain served as
the technical program chair for the workshops on ``Cognitive Wireless
Networks'' (CWNets'07) and ``Wireless Networking for Intelligent
Transportation Systems'' (WiN-ITS'07) held in conjunction with QShine'07:
International Conference on Heterogeneous Networking for Quality,
Reliability, Security and Robustness, during August 14-17, 2007, in
Vancouver, Canada. He served as the technical program co-chair for the
Symposium on ``Next Generation Mobile Networks" (NGMN'06), NGMN'07, and
NGMN'08 held in conjunction with ACM International Wireless Communications
and Mobile Computing Conference (IWCMC'06), IWCMC'07, and IWCMC'08, and the
First IEEE International Workshop on Cognitive Radio and Networks
(CRNETS'08) in conjunction with IEEE International Symposium on Personal,
Indoor and Mobile Radio Communications (PIMRC'08). He is a Senior Member of
the IEEE.
