Recent years internet blended multi-hop wireless networking technology experience growth in diverse sectors ranging from health care to the defense industry. An immense internet data traffic quantity depends on the transmission control protocol (TCP) due to its reliable data carrying ability between end process. TCP's congestion control algorithm performance under multi-hop wireless networks (MWN) is heavily influenced by retransmission timer (RT timer). The retransmission timeout (RTO) algorithm governs RT timer's clock duration. In MWN environment, Jacobson RTO prediction fails to endure sudden traffic delay spike that occurs due to inadequate recovery time during a link failure. In this paper, an analysis carried out to study the RTO's negative impact on TCP's performance under the multi-hop wireless scenario.
