Routing algorithm plays a critical role in determining the performance and reliability of a satellite network. Since the resources in satellite networks are constrained, it is a big challenge to find paths that satisfy all QoS requirements in a low cost for satellite network users. In this paper, a novel routing scheme together with two multi objective optimization routing algorithms-prior order algorithm and beehive algorithm are proposed to solve this problem in hierarchical satellite networks. Simulation results show that the proposed routing method can achieve efficient optimized in all preset QoS parameters and performs well in hierarchical satellite network.
