The Hierarchical-Cluster Topology Control Strategy of InterPlaNetary Internet Backbone based on Libration Points

The concept of InterPlaNetary (IPN) Internet was proposed by National Aeronautics and Space Administration (NASA). The IPN Internet could provide Internet-like services crossing interplanetary distances in support of deep space exploration, which includes backbone network, access network, and planetary network. The IPN backbone topology control strategy based on Libration points was studied in this paper. Firstly, the location and stability of Libration point is simulated by celestial mechanics. Secondly, a novel Hierarchical-Cluster model of IPN backbone network is proposed to simplify topology design. Then Intra-Cluster Link and Inter-Cluster Link are analyzed in detail. Finally, the optimal handover moment is gotten by critical angle which to use relay theory, and the total number of handover times is calculated within a relative period between Uranus and Neptune cluster.

Koncepcja interplanetarnego Internetu IPN została zaproponowana przez NASA. W artykule omówiono strategię kontroli topologii szkieletu bazującą, na punkcie Libration. Na wstępie przeanalizowano stabilność systemu a następnie model hierarchiczny klastrów. Wreszcie analizowano przełączenie połączeń między stacjami bazowymi – handover.
