Paper Title
An Enhancement And An Implementation Of TCP Vegas Over Manets
Abstract
Abstract: We examine the performance of the TCP protocol. In addition, work on using TCP (Transmission Control
Protocol) to provide reliable data transmission has been performed for the purpose of smooth integration with the wired
Internet. In the wired Internet, TCP-Vegas is a well-known transport protocol which takes into account existing network
conditions. However, TCP-Vegas cannot be directly applied to MANETs because a route change can make the BaseRTT
used over a previous path obsolete. It has been shown in the literature that the congestion control mechanism of TCP reacts
adversely to packet losses due to temporarily broken routes in wireless networks. Through simulations using ns-2, we
observed that TCP-Vegas-Adhoc outperforms the standard TCP-Vegas protocol especially under high mobility scenarios
over both reactive and proactive ad hoc routing protocols such as AODV and OLSR.
