Transport Model of Uniform Random Hypergraph for Low Earth Orbit Networks

The architecture of delay tolerant networks (DTN) provides a kind of communication system for growing complexity of space communication. Aiming to low earth orbit satellite networks, the data is encapsulated into multiple bundles and transmitted between a small satellite near earth and the ground stations by using the bundle protocol of DTN. During the process of data transport and the retransmission of the wrong bundle, a random uniform hypergraph model is constructed by using of random hypergraph, and the structure diagram of bundle transmission is also constructed. The model can obtain the relations of the error probabilities of bundles and the structure of hypergraph, and characterize the process of data transport between the satellite and the ground stations. Simulation results show that the error probabilities of bundles and the structure of hypergraph are closely related.
