Multiservice on-demand routing in space information networks

摘要

Different network applications services have difference requirement of performances in space information networks, so a new architecture and a double-layered satellite backbone model of space information networks have provided. Based on this model, a multiservice on-demand routing protocol (MOP) in space information networks is developed. MOP protocol can divide difference traffic classes by using different optimized conditions during the routing calculation, and make routing program adapting acquirement of QoS(quality of service) of different traffic classes. Simulation studies further record and confirm the positive characteristics of MOP protocol in mean end-to-end delay and links' congestion etc.
