Cognitive radio (CR) is a promising technology for future wireless spectrum allocation to
improve the usage of the licensed bands. However, CR wireless networks are susceptible to …

In cognitive radio systems, primary user emulation (PUE) attack means that an attacker
sends primary-user-like signals during the spectrum sensing period such that honest …

Increasing demand on wireless communications also increases the issues related to
communication security. Among different security solutions, physical layer security have …

Cognitive radio based cooperative spectrum sensing (CSS) is severely affected when some
secondary users maliciously attack it. Two attacks regarded as key adversaries to the …

Collaborative spectrum sensing is vulnerable to data falsification attacks, where malicious
secondary users (attackers) submit manipulated sensing reports to mislead the fusion …

Primary user emulation (PUE) attacks, where attackers mimic the signals of primary users
(PUs), can cause significant performance degradation in cognitive radio (CR) systems …

Frequency hop** (FH) has been the most popularly considered approach for alleviating
the effects of jamming attacks. We re-examine, the efficacy of FH based on both …

Primary user emulation attack (PUEA) is a denial of service (DoS) attack unique to dynamic
spectrum access (DSA) networks. While there have been studies in the literature to detect …

Cognitive Industrial Internet of Things (CIIoT) permits Secondary Users (SUs) to use the
spectrum bands owned by Primary Users (PUs) opportunistically. However, in the absence …

This study considers jamming and anti‐jamming in interference channels by way of smart
hop**; and differs from the existing research studies that focus on random hop** in …
