Cooperative spectrum sensing is regarded as an efficient way to detect the spare spectrum
in cognitive radio networks (CRNs), where malicious secondary users (SUs) can launch the …

Cognitive radio networks are a promising solution to the spectrum scarcity issue. In cognitive
radio networks, because of the low reliability of individual spectrum sensing by a single …

In cognitive radio networks (CRNs), cooperative spectrum sensing performed by multiple
users is able to improve the sensing performance of the cognitive system since available …

Cognitive radio is a promising technology to improve the utilization of wireless spectrum
resources. A serious threat to cognitive radio networks (CRN) which sense the spectrum in a …

In this paper we investigate the problem of cooperative spectrum sensing (CSS) in cognitive
radio networks (CRNs) in the presence of malicious attacks from secondary users (SUs). We …

Cooperative spectrum sensing (CSS) for vacant spectrum is one of the key techniques in
cognitive radio networks. However, most of CSS schemes assume secondary users (SUs) to …

In order to resist the attack from malicious Cognitive Radio (CR) users, a reputation-based
collaborative spectrum sensing model is proposed in this paper. In this model, each …

Cooperative spectrum sensing is an efficient way to improve the spectrum utilization in
cognitive radio networks (CRNs), while the system performance of such CRNs is often …

Cooperative spectrum sensing (CSS) is one of the vital mechanisms of cognitive radio (CR),
however, its security area has attracted very little attention, which is vulnerable to the attacks …

Cooperation can improve the performance of spectrum sensing by taking advantage of
diversity gains. However, in the process of cooperative spectrum sensing, malicious users …
