Cognitive radio (CR) is the enabling technology for supporting dynamic spectrum access. This sort of communication paradigm can utilize increasingly scarce spectrum resources more efficiently and has become one of the the hot issues of wireless communication in recent years. With in-depth research, some unique security risks of the CR network has been revealed. A new method named RF "Distinct...
Reliable detection of intrusion is the basis of safety in cognitive radio networks (CRNs). So far, few scholars applied intrusion detection systems (IDSs) to combat intrusion against CRNs. In order to improve the performance of intrusion detection in CRNs, a distributed intrusion detection scheme has been proposed. In this paper, a method base on Dempster-Shafer's (D-S) evidence theory to detect intrusion...
The wavelet edge detection had a wide application in signal processing. In reference [1], Zhi Tian and G B Giannakis proposed a multiscale products wavelet edge detection based spectrum sensing method. In this paper, the performance of forementioned algorithm is analyzed. Then we compare this method with the edge detection using wavelet multiscale sums. From the analysis and comparison, conclusion...
