Routing Issues for Leo Satellite Constellations
We present diierent issues of routing in LEO satellite constellations. The nature of the problem itself needs further explanations. The exact market of these systems lets many questions open, although some models have been advanced. The structure of the ISLs vary from one design to another and impacts signiicantly the optimization. The movement of the satellites also gives to the system a dynam...
متن کاملInternet Routing over LEO Satellite Constellations
Satellite constellations ooer interesting perspectives for Internet traac routing, since they beneet from a worldwide coverage and do not have the main drawback of geosynchronous satellites : propagation delay. However, because of their low altitude, LEO satellites are in constant motion and exhibit speciic issues for routing. This article presents a general architecture applicable to the integ...
متن کاملGaliLEO: A Simulation Tool for LEO Satellite Constellations
We present GaliLEO, a simulator for the transmission of connection-oriented traffic over a constellation of LEO/MEO (Low / Medium Earth Orbit) satellites. Its scope is limited to the satellites and the stations accessing them, without any modelling of the terrestrial network, but inside this scope the goal is to study the performance of satellitebased communication networks from as many as poss...
متن کاملPerformance Study of Routing Algorithms for LEO Satellite Constellations
A comparative study of routing techniques is carried out on complicated LEO constellations interconnecting high speed terrestrial networks. Shortest path routing as well as optimal routing (flow deviation) methods are applied for balanced and unbalanced traffic load and for uniform and non uniform distribution of the earth stations. The performance of flow deviation method is proved to be very ...
متن کاملComputing call-blocking probabilities in LEO satellite constellations
We present an analytical model for computing call-blocking probabilities in a low earth orbit (LEO) satellite network that carries voice calls. Both satelliteand earth-fixed constellations with interorbit links and handoffs are considered. In this model, we assume a single beam per satellite. Also, we assume that call arrivals are Poisson with a fixed arrival rate that is independent of the geo...
