In a Cognitive Radio Network (CRN), a cognitive node temporarily and opportunistically
uses a channel not occupied by any licensed user. Achieving a rendezvous between any …

Cognitive radio networks provide solutions for the coexistence of primary users (license
holders) and secondary users within a licensed spectrum. In this paper, we present and …

Cognitive radio networks are expected to address and resolve important operational
challenges such as opportunistic spectrum access, spectrum and network heterogeneities …

This paper introduces a novel rendezvous protocol (RAC 2 E) for dynamic control channel
provisioning among cognitive radios in a decentralized and cooperative ad-hoc …

The purpose of cognitive radio (CR) technology is to improve spectrum utilization. In recent
years, dynamic spectrum access (DSA) has become one of critical researches for achieving …

Rendezvous is a vital step for secondary users who want to initiate a communication in
cognitive radio networks. In this paper, we propose a novel Padded-Dyck-Path-based (PDP) …

An important issue in designing multichannel MAC protocols for Opportunistic Spectrum
Access (OSA) is the synchronization between Secondary Users (SUs). Synchronization can …

Two or more nodes need to establish a link on an available channel in a cognitive radio
(CR) sensor network when they want to transmit data. Rendezvous is the process by which …

Rendezvous in cognitive radio networks (CRNs) facilitates cognitive radio (CR) users to find
common channels and establish a communication link. Due to the dynamic radio …

In this paper, we formulate novel threat and defense mechanisms for the Sybil attack
problem in Cognitive Radio Networks (CRN). We present potential identity sampling …
