Application of Artificial Intelligent (AI) techniques to cognitive radio
networks is a promising field of research since such networks should have the capacity to learn and adapt within any layer of the radio communication system.
An implementation of this idea called cognitive radio
(CR) scans wireless spectrum dynamically for the clearest bands and switches seamlessly, establishing intelligent and efficient utilization of radio spectrum while deterring abuse and malicious attacks.
Section 2 provides the brief introduction to cognitive radio
and identification of QoS parameters.
In , a survey of spectrum sensing algorithms for cognitive radio
applications is given.
The conception of Cognitive Radio
networks was proposed by Virginia Polytechnic Institute.
The company's xMax cognitive radio
system was designed to operate in challenging radio frequency environments and is able to automatically detect available channels in wireless spectrum, identify unused frequencies, and if necessary, automatically switch to those frequencies to transmit or receive signals.
systems obtain knowledge and then adjust their operational behavior based on that information.
A novel scheme using cognitive radio
for resource management for clustered ad hoc networks in post-disaster communications has been presented in this paper.

is believed by editors Zhang (Simula Research Laboratory, Norway), Zheng (Southeast U.
Opportunities to use spectrum more intensively might therefore flourish with cognitive radio
access, subject to the design of an appropriate spectrum management framework that does not frustrate the development of such a new generation of devices (FCC, 2003; BRODERSEN et al.
3a working group because its main proponents have long planned for future integration of UWB into cognitive radio
architectures also preferred today by the FCC," said Kirsten West, one of the principals of WTRS.
