• Abstract: This paper studies the problem of mitigating reactive jamming, where a jammer adopts a dynamic policy of selecting channels and sensing thresholds to detect and jam ongoing transmissions. The transmitter-receiver pair learns to avoid jamming and optimize throughput over time (without prior knowledge of channel conditions or jamming strategies) by using reinforcement learning (RL) to adapt transmit power, modulation, and channel selection. Q-learning is employed for discrete jamming-event states, while Deep Q-Networks (DQN) are employed for continuous states based on received power. Through different reward functions and action sets, the results show that RL can adapt rapidly to spectrum dynamics and sustain high rates as channels and jamming policies change over time.

  A novel anti-jamming strategy is proposed based on the idea of deceiving the jammer into attacking a victim channel. Since the jammer's channel information is not known to the users, an optimal channel selection scheme and a sub optimal power allocation are proposed. Simulation results show that the proposed anti-jamming method outperforms the compared RL based anti-jamming methods and random search method.
