Abstract:

Considering “internet of everything” of the future internet of things (IoT), the space-based integrated IoT architecture was designed, and the interference scenarios of the coexistence of satellite and ground was analyzed, with the aid of analyzing the architectures of the spatial information network and space-based access network.Specifi cally, fi rstly, relying on both the integration of satellite network and ground network, and the advanced design concept of decoupling control and data, a spacebased satellite IoT architecture was designed in the presence of the specifi c characteristics of access network and terminals, which included space-based backbone network, space-based access network, ground-based IoT, core network and multimodal IoT terminals.Moreover, the process of space-based control plane was also given.Secondly, interference analysis was carried out for satellite spectrum sharing scenario and satellite-ground spectrum sharing scenario respectively, and preliminary analysis results were presented.

Key words: spatial information network, space-integrated-ground information network, internet of things, interference analysis
