Cognitive Radio (CR) technology enables secondary users (SUs) to opportunistically access
unused licensed spectrum owned by primary users (PUs). It has the potential to significantly …

Cognitive radio is development of wireless communication and mobile computing. Spectrum
is a limited source. The licensed spectrum is proposed to be used only by the spectrum …

In this thesis, we focus on both internal and external sensing in Cognitive Radio (CR)
networks. In internal sensing, individual CRs discover spectrum opportunities via spectrum …
