Abstract :
The characteristics of the transmission delay packets in continuous ARQ (automatic-repeat-request) system, a class of the go-back-N system, are considered. In this ARQ scheme the multiple copies of each packet stored in a buffer, instead of one packet itself, are transmitted to reduce the delay. The generating function of the delay and its average is derived. It is shown that the optimum copy-size minimizing the average delay is given not only by the propagation delay and the packet error rate but also by the traffic intensity.<>
