Cognitive radio networks enable unlicensed users to communicate using the licensed
spectrum without causing interference to legitimate users. To establish a communication …

Cognitive radio network (CRN) is a new networking paradigm in which unlicensed users
with cognitive radios can opportunistically access idle channels in the spectrum of licensed …

Cognitive radio (CR) has emerged as an advanced and promising technology to exploit the
wireless spectrum opportunistically. In cognitive radio networks (CRNs), any pairwise …

Rendezvous is an essential operation for secondary users communicating in a cognitive
radio network (CRN). Because it is infeasible to employ a common control channel in a …

Cognitive Radio (CR) is an emerging technology developed to improve the utilization of
licensed spectra, and a promising solution to alleviate the spectrum shortage problem. In …

This study analyzes the most important influence factors in the literature, which have the
greatest influence on the conversions obtained in a mobile application powered by linked …

Rendezvous is a fundamental operation in cognitive radio networks (CRNs) for establishing
a communication link on a commonly-available channel between cognitive users. The …

Real-time systems are becoming increasingly complex. A modern car, for example, requires
a multitude of control tasks, such as braking, active suspension, and collision avoidance …

In a cognitive radio network (CRN), two nodes have a rendezvous when they tune to the
same channel simultaneously. Providing rendezvous guarantee between any pair of nodes …

A primary challenge in exploiting Cognitive Radio Networks (CRNs), known as the
rendezvous problem, is for the users to find each other in the dynamic open spectrum. We …
