lation study for the evaluation in low earth orbit (LEO) ellations, used for the of high-speed networks, is paper. The proposed model end the traffic process at the supporting successfully the f self-similar traffic sources , ach that has been considered an the well-known Poisson, munications. dy for the establishment of s (ISLs) and the design of the ace segments is presented and of the integr...

Fast computation of outage probability for cellular mobile radio systems

In this paper a new approximate method for the computation of outage probabilities in a mobile radio environment is proposed. It allows one to evaluate the performance of a mobile radio system in the presence of fading, in a very fast and accurate way, while maintaining a very good flexibility as to the application to different network environments. Coding is also considered as a possible choic...

Adaptive cross-layer bandwidth allocation in a rain-faded satellite environment

Two control schemes, based on cross-layer adaptation and a hierarchical parametric optimization of the bandwidth allocation, are described and investigated in a satellite network environment, in the presence of both real-time and best-effort traffic flows. A number of earth stations (traffic stations) operate in different weather conditions, with different levels of fade, which affect the trans...

A Probabilistic Study of Inter-Satellite Links Load in Polar Orbit Satellite Constellations

We analyze the load of the inter-satellite links in polar satellite constellations. Starting from simple considerations on the structure of the underlying network topology, we derive the probability of use of diierent families of links, with various hypotheses on the nature of the traac. Our analysis leads to a simple, practical evaluation of the asymptotical link load, which depends on the pos...
