In this paper, aiming to overcome the problems related to mobility in a Satellite Internet scenario, the data link reliable transmission over a mobile geo-stationary satellite link has been analysed. In such environment, the Selective Repeat (SR) classical version does not perform well due to high BER values and burst errors. In order to cope with these impairments, an Automatic Repeat Request (ARQ) protocol, which represents a SR version particularly suitable to mobile channel characteristics has been considered. A performance analysis of this SR version, through a simulations campaign aimed to the evaluation of throughput and delay measures, is presented in comparison with those of other SR approaches. The results of the analysis show how an accurate design of lower layers can determine an appreciable efficiency gain

Abstract

In this paper, aiming to overcome the problems related to mobility in a Satellite Internet scenario, the data link reliable transmission over a mobile geo-stationary satellite link has been analysed. In such environment, the Selective Repeat (SR) classical version does not perform well due to high BER values and burst errors. In order to cope with these impairments, an Automatic Repeat Request (ARQ) protocol, which represents a SR version particularly suitable to mobile channel characteristics has been considered. A performance analysis of this SR version, through a simulations campaign aimed to the evaluation of throughput and delay measures, is presented in comparison with those of other SR approaches. The results of the analysis show how an accurate design of lower layers can determine an appreciable efficiency gain
