The invention discloses an
aerospace network hierarchical cooperation routing optimization method and
system, and relates to the field of
aerospace information
network communication, and the method comprises the steps: constructing a
system model comprising an unmanned plane,
satellite nodes and a
communication link, defining link attributes, building a routing optimization objective function, introducing a reputation value-based multi-agent cooperation mechanism, and carrying out the routing optimization of the unmanned plane, the
satellite nodes and the
communication link. A hierarchical
reinforcement learning framework is designed, inter-cluster decision and intra-cluster decision are divided, an upper layer selects an inter-cluster path according to
global information, a lower layer plans an unmanned aerial vehicle path and defines a state, an action space and a reward function according to local information, an
intelligent agent interacts with an environment to collect
empirical data, and optimal routing communication is selected in combination with a real-time reputation value after training. Adjustment can be carried out according to network changes; according to the invention, the cooperative reliability is improved through a reputation value mechanism, the decision complexity is reduced through hierarchical learning, the routing performance is optimized, the network robustness, expandability and adaptability are enhanced, and the cooperative communication efficiency of the unmanned aerial vehicle and the
satellite and the
system stability are improved.
