Malicious users can exploit vulnerabilities in cognitive radio networks (CRNs) and cause
heavy performance degradation by denial of service (DoS) attacks. During operation …

Cognitive radio has emerged as a solution to the problem of spectrum scarcity in recent
years. Spectrum sensing is a key task in cognitive radio systems that can be performed …

Cooperative spectrum sensing can be regarded as a promising method to resolve the
spectrum scarcity owing to achieving spatial diversity gain in cognitive radio sensor …

Spectrum sensing is an initial task for the successful operation of cognitive radio networks
(CRN). During cooperative spectrum sensing, malicious secondary user (SU) may report …

We propose and analyze trust-based cooperative spectrum sensing data fusion schemes
against spectrum sensing data falsification attacks in cognitive radio networks. We first …

Trust represents the belief or perception of an entity, such as a mobile device or a node, in
the extent to which future actions and reactions are appropriate in a collaborative …

Cooperative spectrum sensing (CSS) in cognitive radio networks (CRNs) enhances spectral
decision-making precision but introduces vulnerabilities to malicious secondary user (SU) …

Internet of Things (IoT) based medical devices equipped with biosensors are installed at the
patient's location to collect sensitive information, such as body temperature, heart rate, blood …

Cooperative spectrum sensing is one of the key technologies to accurately detect the
primary user (PU) activity in cognitive radio networks (CRNs). However, collaboration …

In a non-centralized cognitive radio network, secondary users (SUs) cooperate in order to
determine the presence of the primary user (PU) signal. This can be accomplished by each …
