A Cooperative Spectrum Etiquette for Cognitive Radio

Cognitive radio technology,which has proposed as a means to promote the efficient use of the spectrum,permits co-existence and competition of multiple radio technologies.However,out-of-order utilization of spectrum resources result in low overall efficiency.Therefore,the basic idea of a cooperative spectrum etiquette is proposed in this paper,The basic idea is that cognitive users of the spectrum intend to share the related information and coordinate the cognitive users depending on the sharing information.Thus,cognitive radio users can coordinate the utilization of spectrum resources and avoid the collision between users when cognitive radio users access available spectrum resource.
