Properties of Blind Rendezvous in Channel Hopping Cognitive Piconets

Rendezvous refers to the ability of cognitive nodes to find each other and form a network, or to find an already operating cognitive network and join it. It is a challenging problem, in particular in channel- hopping cognitive networks. In this paper, we discuss the performance of the probabilistic blind rendezvous mechanism based on the transmission tax-based MAC protocol with cooperative sensing at the MAC level. We investigate the performance of the algorithm, with particular focus on the difference in performance in an emergent vs. a fully operational channel hopping cognitive piconet.
