To tackle the difficulty of imbalanced traffic load when forwarding data packets through multiple hops in LEO satellite network
we propose a collaborative game theory routing strategy with incomplete information.Each node determines the current optimal routing path of the data packets through cooperating with neighbors for locally optimized coalition gain.This strategy distributes and balances the traffic workload among neighbor nodes effectively.Simulations show that compared with satellite routing based on the DSP shortest path or the TLR intelligent routing
the proposed algorithm reduces the average transmission delay by 18.5%
and improves the load balancing of nodes by 65.6%.
