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.
