A control architecture for resource allocation in satellite networks is proposed, along with the specification of performance indexes and control strategies. The latter, besides being based on information on traffic statistics and network status, rel

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

Adaptive Cross-Layer Bandwidth Allocation Policies in a Rain-Faded Satellite Environment

Autor: Celandroni N., Davoli F., Ferro E., Gotta A.

Publikováno v: ISTI Technical reports, 2004

Two adaptive bandwidth allocation methods, called Optimized Centralized (OC) and Optimized Proportional (OP) respectively, were studied for a satellite network environment, in the presence of both real-time, guaranteed performance, and best-effort tr

Complete partitioning allocation policies in a rain faded satellite environment

Autor: Celandroni N., Davoli F., Ferro E., Gotta A.

Publikováno v: ISTI Technical reports, 2003

Two resource allocation methods, based on optimized adaptive complete bandwidth partitioning strategies, have been studied, simulated and compared between them and with a simple allocation scheme that does not apply any optimization criteria. The all

We propose a model that describes the signal fading process due to scintillation in the presence of rain. We analyzed a data set of uplink (30 GHz) and downlink (20 GHz) attenuation values averaged over 1 s intervals. The data are samples relative to

We propose a model that describes the rain attenuation process, which can be useful for designing atmospheric fade countermeasure systems for satellite communications. We analyzed a data set of uplink (30 GHz) and down-link (20 GHz) attenuation value
