Abstract
Recently, FCC has considered for that unlicensed device leases licensed devices’ channel. Therefore, IEEE 802.22 WRAN working group progresses CR (Cognitive Radio) technique that is able to sense and adopt void channels that are not being occupied by the licensed devices. Channel selection is of the utmost importance because it can affect the whole system performance in CR network. Thus, we propose a policy-based dynamic channel selection architecture for cognitive radio network to achieve an efficient communication. We propose three kinds of method for channel selection; the first one is weighted selection, the second one is sequential selection, and the last one is combined selection. We can obtain the optimum channel list using the proposed protocol.
