Fast Online Learning of Antijamming and Jamming Strategies

Competing Cognitive Radio Network (CCRN) coalesces communicator (comm) nodes and jammers to achieve maximal networking efficiency against adversarial threats. We have previously developed two contrasting approaches based on multiarmed bandit (MAB) and value-iterated Q-learning. Despite their differences, both approaches have demonstrated the efficacy of applying a machine learning technique to jointly compute comm and jammer actions in hypothetical two-network competition for an open dynamic spectrum. When sampled channel reward characteristics are time-invariant-i.e., stationarity of learned information, both MAB and Q-learning based strategies have resulted in the best possible reward empirically.
