Jump-Stay Rendezvous Algorithm for Cognitive Radio Networks

Free registration required

Executive Summary

Cognitive Radio Networks (CRNs) have emerged as advanced and promising paradigm to exploit the existing wireless spectrum opportunistically. It is crucial for users in CRNs to search for neighbors via rendezvous process and thereby establish the communication links to exchange the information necessary for spectrum management and channel contention etc. This paper focuses on the design of algorithms for blind rendezvous, i.e., rendezvous without using any centralized controller and Common Control Channel (CCC). The authors propose a jump-stay Channel-Hopping (CH) algorithm for blind rendezvous. The basic idea is to generate CH sequence in rounds and each round consists of a jump-pattern and a stay-pattern.
