Cognitive radios are wireless communication networks that learn and adapt to variations in interference environment by changing their transmission and reception parameters, and as a result achieve much higher spectral efficiency and reliability. The technology relies on rapid and accurate sensing of interference characteristics such as detection and localization of interferers, concepts that have been studied in other frameworks in sensor networks. Cooperative sensing techniques can be applied to cognitive radio systems to increase reliability and accuracy of sensing of the interference environment.
