Systematic Construction of Common Channel Hopping Rendezvous Strategies in Cognitive Radio Networks

Cognitive Radio Networks (CRNs) have emerged as a promising paradigm that can solve the shortage of spectrum resources, providing the ability to adapt and opportunistically exploit the spectrum holes. The rendezvous process allows cognitive users to find a common channel and establish a communication link. In this paper, they focus on the design of fast blind rendezvous algorithms to guarantee that every node should be able to rendezvous in all common available channels. The authors follow a systematic approach by first proposing a role-based algorithm that ensures maximum rendezvous diversity and then extending it to a common strategy through the use of multiples radios.
