Abstract


A simulation model of a packet switching satellite network based on a satellite constellation with different orbit heights is presented. The model is meant for analysis of load and data routing at the initial stages of designing of a satellite constellation. Topology of the network and the load in its nodes are modeled. The notion of load of a node is introduced for modeling. This notion is based on division of the node store on an accepted number of levels. The state of a node is determined by the number of filled levels of the store. The change of the load of a node store is modeled as a process of reproduction and dying out caused by the exchange of load with the surface users of the system and the transit load flow through the node

Keywords


simulation model, packet switching satellite network, satellite constellation, orbital groups of different heights, network topology, load of a network node, process of reproduction and dying out
