A comparison of the congestion control schemes of two TCP variants: Reno and New Reno, in a wireless mesh network is performed and the throughput, propagation delay, number of segments retransmitted and number of duplicate acknowledgements received for four different node densities are analyzed.Abstract:
The Transmission Control Protocol forms the backbone of data communication networks the world over. While TCP congestion control protocols operate efficiently over wired networks, their performance in wireless networks leaves a great deal to be desired. Wireless networks are prone to random packet drops for a myriad of reasons apart from network congestion, such as poor channel characteristics, high BER, the hidden node problem and the number of hops between source and destination. This paper aims to perform a comparison of the congestion control schemes of two TCP variants: Reno and New Reno, in a wireless mesh network and analyze the throughput, propagation delay, number of segments retransmitted and number of duplicate acknowledgements received for four different node densities. The behaviour of TCP in wireless networks is observed and plausible justifications attempted. Overall, TCP New Reno shows 40% higher throughput and 25% lower delay as compared to TCP Reno.read more

TL;DR: The congestion control algorithms in the simulated implementation of SACK TCP are described and it is shown that while selective acknowledgments are not required to solve Reno TCP's performance problems when multiple packets are dropped, the absence of selective acknowledgements does impose limits to TCP's ultimate performance.
