Performance analysis of go-back-N ARQ scheme with selective repeat in intra-block

The performances of the go-back-N ARQ scheme with selective repeat in intra-block (GBN-SR) and revised GBN-SR (Rev-GBN-SR) schemes are analyzed. Using the derived generating function of the service time of a packet, the throughputs of the proposed schemes are compared with that of Benelli's (1986) scheme. It is shown that the proposed Rev-GBN-SR scheme shows good performance in a wider range from low to high packet error rate regions.
