Simple role-based rendezvous algorithm for cognitive ad hoc radio networks

Rendezvous is the process in which two users attempt to meet on a common channel and it is of fundamental importance in cognitive ad hoc radio networks. A cognitive radio blind rendezvous algorithm named simple role-based is proposed that exploits the common channel labelling inherent to wireless networks. The scheme guarantees the simultaneous rendezvous of multiple cognitive users. Analytical expressions are derived for the expected time to rendezvous and maximum time to rendezvous. Numerical results show that the proposed method outperforms the other well-known rendezvous algorithms.
