Abstract :
When a channel-hopping cognitive network experiences a collision with primary user transmission, it may re-form the network by repeating the network formation (rendezvous) procedure, which is costly and time-consuming, or attempt to recover by re-establishing operation on an idle channel from a predefined backup set. In this paper we analyze a practical recovery mechanism implemented atop the transmission tax-based MAC protocol. The recovery mechanism uses a list of backup channels obtained from sensing data. We investigate the performance of the mechanism and show that a small number of backup channels suffices to ensure speedy and reliable recovery.
