Performance evaluation of Matched Filter Detection Based on Non-Cooperative Spectrum Sensing in Cognitive Radio Network

The recent and rapid evolution of wireless technologies has led to a high demand in terms of resources. To solve this prob-lem the idea of cognitive radio has been introduced to facilitate a good spectrum management and efficient use of the spectrum. In this article, a method for the detection of the spectrum with the purpose of detecting the presence of bands of unoccupied frequencies is propo...

Connectivity-based Performance Evaluation for Mobile Cognitive Radio Network

In this paper, we propose a model of mobile cognitive radio network after fully considering the analysis method of network connectivity based on random way-point (RWP) mobility scheme. The closed-form solution of connectivity probability has been derived to evaluate the network performance in this model. And it shows that the network connectivity is related to the size of mobile cognitive radio...

On the throughput performance of cluster-based cognitive radio networks

This paper addresses effect of reporting channel bandwidth on cognitive radio (CR) networks. A cluster based approach is considered where the secondary base station is replaced by a fusion center and a global reporting channel is used instead of local ones. A new approach to select the fusion center based on the general centre scheme in graph theory is proposed. The minimal dominating set (MDS)...

Secrecy performance of threshold-based decode-and-forward cooperative cognitive radio network

This paper evaluates the intercept and outage probability of a decode-and-forward (DF) underlay cognitive radio network. The secondary users are subject to interference limitations from the primary network, with an eavesdropper tapping the second hop of cognitive network, when all the links undergo Rayleigh fading. For this threshold-based system, without assuming that the DF relays can always ...
