Abstract : In this report, we investigate a strategy to avoid or mitigate reactive forms of jamming using a reinforcement learning approach. The mitigation strategy focuses on finding an effective channel hopping and idling pattern to maximize link throughput. We also analyze the feasibility of reactive jamming (including repeater jamming) in a satellite communications scenario, and propose a countermeasure that takes advantage of the constraints associated with reactive jamming.
