Spectrum Sensing Using CSMA Technique

Abstract

Cognitive Radio is an emerging frontier to tackle the ever increasing demand of spectral needs. The most important function of CR is to search for spectrum holes or white spaces in the spectrum. Many techniques has been introduced and researched to increase the efficiency and accuracy of Spectrum Sensing. With the introduction of more complex methods cost of the whole process also increases. The following paper suggests a new idea of involving CSMA technique for spectrum sensing. This paper will give an insight on working of CR and CSMA technique. Later it will put forward the criterion for spectrum sensing and how CSMA can be used for investigate the presence of primary user in the spectrum vicinity.
