Spectrum sensing is the prerequisite of opportunistic spectrum access in cognitive sensor
networks (CSNs) as its reliability determines the success of transmission. However …

Spectrum sensing is essential to identify the presence of primary users (PUs) in cognitive
radio networks. Cooperative spectrum sensing (CSS) obtained from the diversity of different …

Industrial wireless networks (IWNs) are characteristically different from traditional wireless
systems due to harsh radio frequency (RF) environments and applications that impose high …

The present contribution proposes a spectrally efficient censor-based cooperative spectrum
sensing (C-CSS) approach in a sustainable cognitive radio network that consists of multiple …

This study investigates cooperative spectrum sensing (CSS) in cognitive wireless radio
networks (CWRNs). A practical system is considered where all channels experience …

In this paper, we propose a sequential spectrum sensing algorithm for cognitive radio
systems, which we term the sequential shifted chi-square test (SSCT). SSCT has the …

In cognitive radio sensor networks (CRSNs), the sensor devices which are enabled to
perform dynamic spectrum access have to frequently sense the licensed channel to find idle …

Conventional cooperative spectrum sensing (CSS) schemes in cognitive radio networks
(CRNs) require that the secondary users (SUs) report their sensing data separately in the …

In cognitive radio network, the secondary users (SUs) use the spectrum of primary users for
communication which arises the security issues. The status of SUs as legitimate users is …

Conventional cooperative spectrum sensing (CSS) schemes in cognitive radio networks
(CRNs) require that the secondary users (SUs) report their sensing data sequentially to the …
