In cognitive radio, cooperative spectrum sensing can significantly improve the performance
of spectrum sensing. The performance of cooperative spectrum sensing will be impacted …

Cognitive users sense for the availability of the spectrum and share the information among
each other with the help of fusion center (FC). Along with cognitive users, there could be …

In this paper, we introduce cooperative spectrum sensing (CSS) scheme for detection of
primary user (PU) in a cognitive radio network. Our scheme is based on a separating …

Compared with the single user spectrum sensing, cooperative spectrum sensing is a
promising way to improve the detection precision. However, cooperative spectrum sensing …

Spectrum sensing plays an important role in improving the spectrum utilization of cognitive
radio networks (CRN). However, Byzantine attackers may incur the spectrum sensing …

Spectrum utilization is an important factor in Cognitive radio networks, which is
accomplished by analyzing the unused spectrum bands of primary users (PU). The …

The different issues in the wireless channel, such as multipath fading, shadowing, and
hidden terminal problems, limit the sensing abilities of the single user in a cognitive radio …

Cooperative spectrum sensing (CSS) is crucial for cognitive radio (CR) to improve spectrum
sensing performance. However, the cooperative paradigm is threatened by Byzantine …

Spectrum sensing describes, whether the spectrum is occupied or empty. Main objective of
cognitive radio network (CRN) is to increase probability of detection (Pd) and reduce …

Spectrum sensing is an important issue in cognitive radio networks. But due to noise and
shadowing effects, the sensing results of sensors may be erroneous. This will degrade the …
