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
