Improving the optimum generalised stop-and-wait ARQ scheme
D. Suresh Babu, T.S. Vedavathy · Electronics Letters · 1986
Instead of waiting for the acknowledgments from all the copies of a single data block sent, as in the optimum generalised stop-and-wait ARQ scheme, the transmitter in the proposed scheme starts sending an optimum number of copies of the next block in the queue, soon after receiving the positive acknowledgment from the receiver, thereby further improving the throughput efficiency.
