• Abstract: This paper addresses the challenge of anti-jamming in moving reactive jamming scenarios. The moving reactive jammer initiates high-power tracking jamming upon detecting any transmission activity, and when unable to detect a signal, resorts to indiscriminate jamming. This presents dual imperatives: maintaining hiding to avoid the jammer's detection and simultaneously evading indiscriminate jamming. Spread spectrum techniques effectively reduce transmitting power to elude detection but fall short in countering indiscriminate jamming. Conversely, changing communication frequencies can help evade indiscriminate jamming but makes the transmission vulnerable to tracking jamming without spread spectrum techniques to remain hidden. Current methodologies struggle with the complexity of simultaneously optimizing these two requirements due to the expansive joint action spaces and the dynamics of moving reactive jammers. To address these challenges, we propose a parallelized deep reinforcement learning (DRL) strategy. The approach includes a parallelized network architecture designed to decompose the action space. A parallel exploration-exploitation selection mechanism replaces the $\varepsilon $-greedy mechanism, accelerating convergence. Simulations demonstrate a nearly 90\% increase in normalized throughput.

  An intelligent jammer is able to change its policy to minimize the probability of being traced by legitimate nodes. Existing anti-jamming methods are not applicable here because they mainly focus on mitigating jamming attacks with an invariant jamming policy. This paper proposes a jamming type recognition technique working alongside an anti-jamming technique.

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.
