Abstract: Different from the MAC of IEEE 802.11, the application of IEEE 802.22 suffers the uncertain spectrum and frequency width, which can not ensure the access of mobile users to be valid. To solve the problem, in this paper, we modify the CSMA/CA mechanism in order to make it suit the Cognitive Radio environments, in which the spectrum can be effectively used. We validate the modification by numerical analysis.
