Special Issue on

Cognitive Radio Networks: A Practical Perspective*

Contemporary wireless system design must typically incorporate increased
bandwidth requirements due to the persistent trend for higher wireless
multimedia data rates. Increased bandwidth may be achieved by developing
efficient strategies for spectrum management. The cognitive radio concept
proposes to push efficiency in spectrum access and resource allocation
beyond its traditional limits, by introducing spectrum sharing, coexistence,
and cooperation among heterogeneous wireless networks. This approach has
been worldwide recognized by standardization and regulation bodies, and a
number of wireless technologies could benefit from it.
Examples abound. WiFi networks could operate in other portions of the
spectrum than the traditional ones thus avoiding the already overcrowded ISM
bands. Sensor networks deployed in factories or highly interfered
environments could adaptively select the frequency bands that are less used
by other nearby wireless devices and allow reliable data transfer.
Communications systems using OFDM could resort to non-contiguous carriers
usage for dynamic spectrum access, thus favoring coexistence with other
technologies while still providing high data rates.

Important technical challenges still need to be overcome, however, in order
to achieve successful coexistence and cooperation among heterogeneous
systems. Open research issues cover a wide range of system aspects, from the
hardware component up to network layer design. Technical, economical, and
regulatory challenges need to be addressed as well. In order to compel the
cognitive networking vision, experts in various aspects of wireless design
must come together for a joint effort towards system level optimization.

The objective of this special issue is to present a collection of
high-quality papers that report the latest research advances in the design
and implementation of cognitive networking, as well as survey papers on the
major challenges and possible solutions that lead the path to real-world
cognitive radio systems.

We solicit both academic and industrial contributions, which are original,
previously unpublished and not currently under review by another journal.

The submitted papers should focus on practical aspects of cognitive radio
networks, system design issues, implementations/testbeds, or measurements in
real environments. Topics of interest include, but are not limited to:

Centralized and distributed spectrum coordination services
Regulation issues and use cases
Practical applications and standards for cognitive radio (IEEE802.22, IEEE
SCC41,?)
Radio spectrum maps, database and usage of white spaces
Software defined radio solutions
Coexistence among heterogeneous wireless technologies (cellular, WiFi,?)
Implementation of sensing and dynamic spectrum management
Design and implementation of cognitive MAC and network-layer protocols
Physical layer and advanced signal processing
Cross-layer optimization and reconfiguration solutions
Security in cognitive radio networks
Machine learning and pattern recognition for network identification
Evaluation of different design and implementation choices (e.g., sensing vs.
use of radio spectrum maps)
Feasibility and implementation challenges of cognitive radio solutions in
real devices
Testbed and field trials with cognitive radio networks
Manuscript Submission
The papers should be tutorial in nature to help non-expert readers gain a
good understanding of the topic. The papers should also discuss recent
advances and future research topics. Authors must follow theIEEE Wireless
Communications Magazine guidelines for preparation of the manuscript and
submit it via Manuscript Central at http://mc.manuscriptcentral.com/ieee-wcm.
