Abstract

This letter proposes a simple modification called reverse acknowledgement (RA) scheme to a negative acknowledgement (NAK)-based selective repeat automatic repeat request (SR-ARQ) protocol for its fast loss recovery. By adopting the RA scheme, a NAK-based SR-ARQ receiver can detect and recover retransmission failures without invoking retransmission timeouts (RTOs). By OPNET simulations, we evaluate the performance of the RA scheme in terms of the transport delay and re-sequencing delay and show that the RA scheme considerably improves the performance of NAK-based SR-ARQ.
