dc.description.abstract | Due to limited buffer space available at routers, the packets in the Internet gets lost or dropped, especially when the network is congested. Automatic repeat request (ARQ), is an error-control method that uses acknowledgments and timeouts to decide retransmission of messages to achieve reliable data transmission. However, the re-transmission of a lost packet further increases the congestion in the network, and hence the end-to-end delay of other coexisting flows. This paper aims at improving the performance of ARQ schemes by introducing a lightweight re-transmission mechanism called LW-ARQ based on the concept of caching of packets at intermediate routers that are indented to be dropped. To evaluate the performance of proposed LW-ARQ scheme, we chose to implement it over TCP protocol considering that TCP has become a de-facto transport layer protocol standard for the Internet. However, the proposed LW-ARQ scheme can be integrated with any protocol that uses either stop-and-wait or sliding window based ARQ scheme to handle packet losses. On analyzing the results obtained by performing simulations, we found that the proposed LW-ARQ scheme improves the average end-to-end delay performance of the TCP protocol. | en_US |
