Performance Analysis of TCP Variants under MANET Environment and using NS-2

Anwar Khan ^[2] | Dharmendra Sharma

Abstract: TCP was designed for wired networks and the sender assumes that packet loss is an indicator of network congestion, but this assumption may not apply to Mobile Ad hoc Networks (MANETs). In Mobile Ad Hoc networks, performance of the standard TCP is significantly degraded due to characteristics of MANET such as route failures due to node mobility and link errors. In this paper, the authors investigate the performance of TCP variants such as New Reno, SACK, TCP Tahoe and Vegas. Simulation results from the implementation of different static scenarios have been obtained. Different routing protocols such as Ad hoc On-Demand Distance Vector (AODV) and Destination Sequence Distance Vector (DSDV) have been investigated to obtain the performance of TCP variants in this paper.
