A new ARQ scheme using a go-back-N protocol

In this paper a new protocol suitable for communication systems using error detecting codes is described. This scheme is similar to a Go-Back-N protocol, but it presents higher performance. The throughput of the protocol is determined through a theoretical analysis. The results show that the proposed protocol maintains, as the Go-Back-N schemes, a simple implementation structure, but at the same time permits to achieve high throughput values. In particular, for high error rates in the communication channel the described protocol achieves performance comparable with that of the selective protocol with infinite buffer.
