Dogfight in Spectrum: Jamming and Anti-Jamming in Multichannel Cognitive Radio Systems
2009
GLOBECOM 2009 - 2009 IEEE Global Telecommunications Conference
Primary user emulation attack in multichannel cognitive radio systems is discussed. An attacker is assumed to be able to send primary-user-like signals during spectrum sensing period and thus jam the secondary user sensing the corresponding channels. An anti-jamming approach for the secondary user is to do random hopping over the multiple channels. When different channels have different qualities (e.g. probabilities of being idle), the secondary user needs to find the optimal tradeoff between
