In cluster-based cooperative cognitive radio networks (CCRNs), spectrum sensing and
decision making processes to determine whether the primary user (PU) signal is present or …

Cognitive radio (CR) networks have been active area of research because of its ability to
opportunistically share the spectrum. A cluster-based cooperative spectrum sensing (CCSS) …

The cognitive radio (CR) technology is being considered as a novel approach for improving
the spectrum utilization by detecting and using the vacant spectrum bands of licensed users …

In cooperative cognitive radio networks (CCRNs), the reporting time is consumed by all
secondary users (SUs) for reporting the sensing results to the central node or fusion center …

Cluster based cooperative spectrum sensing (CSS) in cognitive radio networks provides for
reduced sensing error, reporting delays and improved energy efficiency, in a practical …

In cognitive radio network, cooperative spectrum sensing (CSS) can improve the sensing
performance on the absence of a primary user, when the sensing channel is in severe …

This paper proposes clustering schemes to solve the sensing throughput tradeoff problem in
cooperative cognitive radio networks (CCRNs). The throughput of CCRNs extremely …

In cooperative spectrum sensing (CSS), a multibit combination rule shows better sensing
performance than one-bit hard combination rules at the sacrifice of the reporting overhead …

A large number of previous works have demonstrated that cooperative spectrum sensing
(CSS) among multiple users can greatly improve detection performance. However, when the …

Cooperative spectrum sensing may cause a high sensing overhead to secondary users
(SUs) and induce much interference to primary users (PUs) due to detection result reporting …
