A cross‐layer anti‐jamming method in satellite Internet

In view of the diverse jamming environment, single-level anti-jamming method faces some challenges such as poor timeliness, high cost and effect. this paper, routing delay, overhead diversified threats are comprehensively considered. addition, a cross-layer is proposed in scenario busy satellite Internet communication. The involves two levels: link-layer based on path repair network-layer reconstruction. On one hand, channel selected improved Q-learning algorithm to confront common jamming. other route from source destination node high-intensity Finally, simulation results show that, compared with algorithms, can achieve higher efficiency, lower cost, more robust routing.
