In this paper,

An empirical study has been done by simulation andanalysis of TCP variations under AODV, DSDR , DSR ,OLSR routing protocol

We studied multiple variations of TCP, such as R e n o ,N ew - R en o , Vegas , and T a h o e

We carried out observations for different TCP packetsunder several QoS metrics such as D r o p , T h r o u g h p u t ,Delay, and J i t t e r

In t r o d u c t io n



AODV - Ad hoc On-Demand Distance Vector Routing protocol (AODV)is an on demand routing protocol. To find a route to the destination, thesource node floods the network with Route Request packets.

DSDV - Destination-Sequenced Distance Vector routing protocol

(DSDV) is one of the most well known table-driven routing algorithmsfor MANETs which is based on the Distributed Bellman-Fordalgorithm.

DSR - Dynamic Source Routing (DSR) is a kind of source routing basedon two procedures: route discovery and route maintenance.

OLSR - Optimized Link State Routing protocol (OLSR) is based on link state algorithm and it is proactive in nature.

T a h o e - Tahoe refers to the TCP congestion control algorithm which

was suggested by Van Jacobson in his paper.

R e n o - It retains the basic principle of Tahoe, such as slow starts andthe coarse grain re-transmit timer. However it adds some intelligenceover it so that lost packets are detected earlier and the pipeline is notemptied every time a packet is lost.

New-Reno - New-Reno is a slight modification over TCP-Reno. It isable to detect multiple packet losses and thus is much more efficient thatRENO in the event of multiple packet losses.

Vegas - Vegas is a TCP implementation which is a modification of Reno.It builds on the fact that proactive measures to encounter congestion aremuch more efficient than reactive ones.
