The internet of everything (IoEs) has become a well-known tool for transforming the concept
of connected environments into reality in near future. The cognitive radio network is a …

This article investigates the performance of cooperative spectrum sensing (CSS) in a
heterogeneous multihop cognitive radio (CR) system in which N secondary users (SUs) with …

The secondary users can opportunistically utilize the spectrum holes left by the licensed
users (also called primary users PUs) with the help of cognitive radio (CR) technology. The …

This letter considers cooperative spectrum sensing (CSS) in a heterogeneous cognitive
radio network, where K nonidentical cognitive users (CUs) and a fusion center (FC) …

Cognitive radio technology is a potential contender to fulfil the demand of
spectrum/bandwidth for a large number of connected devices of the next-generation internet …

The current paper studies comprehensive analysis of various cooperative spectrum sensing
(CSS) schemes in generalized κ− μ fading environment. More precisely, the optimization of …

In this paper, we propose a cooperative cognitive radio network (CCRN) based on energy
detection and hard-decision fusion. The performance characteristics are investigated …

In this paper, the analytical performance evaluation of the cooperative cognitive radio
network (CCRN) with hard-decision and soft-data fusions is investigated in the presence of …

In order to address the issue of spectrum scarcity, cognitive radio (CR) offers an effective
usage of radio spectrum resources by offering dynamic spectrum access. One kind of …

This paper presents, optimization analysis of energy detection based cooperative spectrum
sensing system (CSSS) with hard-decision combining. Several system parameters are …
