WebJamming has been a major denial-of-service attack to wireless communications [1], [2]. By intentionally emitting jamming signals, adversaries can disturb network communica-tions, resulting in throughput degradation, network partition, or a complete zero connectivity scenario. Reactive jamming is one of the most effective jamming attacks. A reactive WebReinforcement learning (RL) is being considered for future SATCOM systems due to its inherent capability to self-learn the optimum decision-making policy under different scenarios. This capability enables SATCOM systems to manage their resources judiciously and mitigate jamming attacks autonomously without prior jammer type classification. fisher model pcd-5700 a repair
