ABSTRACT: In this
paper, we conduct a cross-layer analysis of both the jamming capability of the cognitiveradio-based
jammers and the anti-jamming capability of the cognitive radio networks (CRN).
We use a Markov chain to model the CRN operations in spectrum sensing, channel
access and channel switching under jamming. With various jamming models, the
jamming probabilities and the throughputs of the CRN are obtained in
closed-form expressions. Furthermore, the models and expressions are simplified
to determine the minimum and the maximum CRN throughput expressions under
jamming, and to optimize important anti-jamming parameters. The results are
helpful for the optimal anti-jamming CRN design. The model and the analysis
results are verified by simulations.
