Handoff Framework for 4G LTE and Cognitive Radio Network Based on Common Control Channel

Cognitive Radio Network (CRN) users can be divided into two categories. First one is Primary User (PU) which user has licensed to use assured spectrum band. Another one is Secondary User (SU) which user activates in the ISM bands and also uses PUs spectrum without snooping that. In the term of the job, CR has four main functionalities. Those are spectrum intellection, spectrum management, spectrum distribution and spectrum handoff. The dynamic use of the accessible unused licensed spectrum can be made by spectrum handoff. The accuracy of the spectrum handoff has carried the confidence about cognitive radio networks to fulfill the increasing demand for extra spectrum. This research proposed framework for CCC based channel selection and spectrum handoff to CRN.
