Cognitive Radio is utilized to exploit the existing wireless spectrum opportunistically, in which way to alleviate the spectrum shortage problem. It is of fundamental importance in cognitive radio adhoc networks for users to meet on a common channel via rendezvous and thereby establish communication links. In this paper, we investigate the probability analytic model to discuss the problem of rendezvous...
In traditional cognitive radio ad hoc networks (CRAHNs), each unlicensed node senses and attains its own idle frequency channel. Considering that the available channels at different nodes may be different, a dedicated common control channel (CCC) facilitates the exchange of the spectrum availability information of each node, and then forthcoming communication nodes tune to the same frequency channel...
