* Spectrum mobility: Process by which a cognitive-radio user changes its frequency of operation. Cognitive-radio networks aim to use the spectrum in a dynamic manner by allowing radio terminals to operate in the best available frequency band, maintaining seamless communication requirements during transitions to better spectrum.<br/>
* Spectrum sharing: Spectrum sharing cognitive radio networks allow cognitive radio</p><p>
