Jamming-Aware Randomized Spectrum Sharing in Cognitive Radio Communication Networks
Abstract:
We investigatein this paper spectrum sharing techniques for multiple unlicensed userstoshareanavailablesparechannelincognitiveradionetworks. Inparticular,consideringasingle-slotted aloha channel access model, we develop an effcient transmission framework that enablesthe detection of jamming attacks. The proposed transmission strategy adopts a randomized PN-codeassignmentforeach transmissionslot. Furthermore,giventhePN-basedtransmissionframe-work, a two-step jamming detection algorithm is also devised by combining an energy detectorand a correlation detector. Theoretical analysis of the detection performance is presented and theimpactofsystemparameters is demonstratedthroughnumericalexamples.
