Performance evaluation of LEO satellite constellations with inter‐satellite links under self‐similar and Poisson traffic (original) (raw)

A real time simulation study for the evaluation of traffic flow in low earth orbit (LEO) satellite constellations, used for the interconnection of high-speed networks, is presented in this paper. The proposed model simulates end to end the traffic process at the packet level, supporting successfully the implementation of self-similar traffic sources , a modeling approach that has been considered more realistic than the well-known Poisson, for real-time communications. An in-depth study for the establishment of inter-satellite links (ISLs) and the design of the terrestrial and space segments is presented and the performance of the integrated system is evaluated in terms of delay and throughput parameters.
