Cognitive radio technologies enable users to opportunistically access unused licensed
spectrum and are viewed as a promising way to deal with the current spectrum crisis. Over …

Mobile edge computing (MEC) is a promising technique to improve the quality of
computation experience for mobile devices by providing computation resources in their …

We integrate a wireless powered communication network with a cooperative cognitive radio
network, where multiple secondary users (SUs) powered wirelessly by a hybrid access point …

Communication technologies supply the blood for smart city applications. In view of the ever-
increasing wireless traffic generated in smart cities and our already congested radio access …

Abstract Much interest in Cognitive Radio Networks (CRNs) has been raised recently by
enabling unlicensed (secondary) users to utilize the unused portions of the licensed …

This paper investigates a buffer-aided cooperative NOMA system, where a source is
connected to multiple destinations through a buffer-aided NOMA relaying. We aim to …

This paper presents an analytical framework for the probability of spectrum hole utilization
(PSHU) of a cognitive radio system with soft cooperative spectrum sensing (CSS) under a …

A resource allocation approach is proposed for wireless powered cooperative cognitive
radio network (WP-CCRN) in this paper, where multiple secondary users (SUs) capture both …

In cognitive radio networks (CRNs), primary users (PUs) can leverage secondary users
(SUs) as cooperative relays to increase their transmission rates, while SUs will in return …

To alleviate the spectrum scarcity problem in the licensed cellular networks (LCNs), we
introduce a new paradigm called cognitive multihoming (CM), where a cognitive radio (CR) …
