Spectrum sensing vulnerabilities in cognitive radio (CR) networks are being actively investigated, where most research focuses on mechanisms that deal with possible attacks without examining optimal sensing disruption strategies. This paper addresses the optimal design and analysis of a power-limited intelligent adversary to a CR network. The adversary targets unused bands and puts energy into them...
Recent studies show that spectrum sensing in cognitive radio exposes vulnerabilities to adversaries. An intelligent adversary can launch sensing disruption in the sensing duration, by putting spoofing signals in allowable bands to prevent secondary users from accessing. In the meantime, the adversary can also attack secondary users by traditional jamming, once they access the spectral bands and start...
