Integral and crucial to performance of wireless sensor networks (WSNs), and specifically
industrial wireless sensor network (IWSN) is stable, robust, reliable, and ubiquitous …

Abstract In Orthogonal Frequency Division Multiplexing OFDM, a cyclic prefix (CP) is applied
to reduce the intervention between symbols. The CP results in bandwidth wastage, and the …

State-of-the-art energy detection (ED) based spectrum sensing requires perfect knowledge
of noise power and is vulnerable to noise uncertainty. An eigenvalue-based spectrum …

Non-Orthogonal multiple access (NOMA) and Cognitive radio (Cr) are seen as one of the
most promising techniques, which improves the utilization of the spectrum in 5G. The …

In this letter, we consider cooperative spectrum sensing with the presence of malicious
users. The detailed detection performance and sensing efficiency are formulated to analyze …

The maximization of Secondary user (SU) throughput has been studied extensively in
honest cooperative spectrum sensing (CSS). However, when primary user emulation attacks …

Spectrum sensing is an essential function in cognitive radio systems for dynamic spectrum
access. Multinode sensing is a technique being used in cognitive radio networks to enhance …

Spectrum sensing is a primary and an essential function in cognitive radio (CR) for dynamic
spectrum access. Cognitive user should detect the whitespaces or vacant frequency bands …

Spectrum sensing is a key component to realise the cognitive radio. The main requirements
of spectrum sensing are the prediction of signal status in multiple frequency bands in a low …

Enhancing the throughput of cognitive radio network in the presence of malicious cognitive
radio user (MCRU) is addressed in this paper. We have considered the impact of MCRU on …
