Study on Routing Algorithms in Space-based Internet

The core of Space-based Internet（SI） is satellite communication network,while routing algorithm is the key technology of satellite communication network and the foundation for reliable and effective information transmission.Based on analysis of some typical routing algorithms a novel routing algorithm known as Simple QoS-qualified Routing Algorithm（SQRA） is proposed,which could improve integrated performances on the premise of no increase in computation complexity.Simulation results indicate that SQRA could be implemented easily,and acquire better performances.In addition SQRA could satisfy the different requirements for QoS performance by business data type A or B.
