Abstract
In this paper, we provide a quantitative analysis of the effect of improvin g the throughput characteristics by installation of a sequence control buff er in the receiver applied to the continuous ARQ (go-back-N) scheme, which is a typical method of transmission control in data communication networks, for the case when a simultaneous retransmission of multiple copies is allo wed. A known method of improvement of the transmission characteristics is t o store the correctly received data blocks in a buffer in cases when error recovery procedures are initiated, although no methods of accurate evaluati on under the conditions of a reduced throughput have been proposed. In this paper, the error recovery process is expressed as a two-step hierarchical model. In the analysis model prepared for the purposes of this study, the r etransmission cycles repeated for error recovery purposes and retransmissio n sets corresponding to the continuous error recovery operations are repres ented in the form of a two-step retransmission diagram. Using this model, w e have demonstrated that, based on the 1223-type revised mean-value analysi s that allows for the estimation of mean values of the influence between th e sets, it is possible to considerably reduce the volume of calculations. U sing the proposed method of analysis, it is possible to estimate the actual transmission rate within 2.5% of its absolute value, and the round trip de lay with a time-dependent remote control can also be approximated.
