Cognitive radio has been widely considered as one of the prominent solutions to tackle the
spectrum scarcity. While the majority of existing research has focused on single-band …

We consider a two-stage sensing scheme for cognitive radios where coarse sensing based
on energy detection is performed in the first stage and, if required, fine sensing based on …

For sensor network aided cognitive radio, cooperative wideband spectrum sensing can
distribute the sampling and computing pressure of spectrum sensing to multiple sensor …

With the application of semantic Web service and semantic Grid service, the similarity
measure between services are more and more important in the processing of service …

Cognitive radios are indispensable to shift paradigm from conventional exclusive spectrum
assignment to dynamic spectrum access. They can boost up spectrum utilization …

Reliable spectrum sensing is one of the most crucial aspects for the successful deployment
of cognitive radio (CR) technology. For CR, it is not possible to transmit on a licensed band …

Cooperative Cognitive Radio Networks: The Complete Spectrum Cycle provides a solid
understanding of the foundations of cognitive radio technology, from spectrum sensing …

The successful deployment of dynamic spectrum access requires cognitive radio (CR) to
more accurately find the unoccupied portion of the spectrum. An accurate spectrum sensing …

This paper presents an autonomous cognitive radio (CR) architecture, referred to as the
Radiobot. This model goes beyond adaptive radio systems to exploit the main ingredients of …
