An ongoing secondary user still needs to sense when a primary user accesses its channel and then either moves to another idle channel or moves to a buffer. In the latter case, the secondary user's call waits in the buffer until either a channel becomes available or a predefined maximum waiting time expires. In this letter, an analysis of reconnection opportunity is presented for the queued secondary calls in the buffer in a cognitive radio network under unreliable sensing through developing a 3-D Markov process, where the unreliable sensing is modeled by different false alarm and misdetection events for both initiating and ongoing secondary users. A closed-form expression of the reconnection probability for an arbitrary secondary call in the buffer is obtained and the numerical computation is provided to highlight the analysis.
