Aiming at QoS routing problems in double-layered LEO/MEO satellite networks, a novel routing algorithm, TAHR, which takes advantage of hierarchical architecture and traffic distribution capacity of double-layered satellite networks, is proposed. An analysis on several performance metrics, such as end-to-end delay, jitter of delay, routing maintenance signaling load and ISL utilization rate in LEO layer, is made. Simulation results show that TAHR can be applied to QoS-guaranteed routing in LEO/MEO double-layered satellite networks effectively while cut down routing maintenance load and improve throughput greatly.
