Paper Title : Performance Analysis of Some TCP Variants for Routing over Mobile Ad hoc Networks
Author Name : Ibrahim K. Tabash, M. Salim Beg, Nesar Ahmad
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 effects of node’s mobility on the performance of TCP variants such as Reno and Vegas. Reno views the packet loss as signal of network congestion, while Vegas uses the difference in the expected and actual throughput rates as network congestion indicator. Simulation results from the implementation of different static and dynamic 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.
