As TCP is more popular and dominant congestion control technique. TCP congestion control techniques assure reliable data transmission and detecting congestion based on packet loss or packet delay. When the network is heavily loaded there is a loss of network performance called congestion. There are two types of network that is Homogenous and Heterogeneous network and various TCP variants which can be evaluated using network simulators. There is not a fair bandwidth allocation in a homogeneous network, but fair in heterogeneous network and has a significantly lower delay. This paper will present various TCP Variants related to TCP Vegas.

“…In [1], it is explained that this window serves to thwart the communication link between the communicating nodes from getting overwhelmed by traffic. Overwhelmed networks lead to packet losses, which according to [2] may be caused by malicious packet dropping and link error.…”

-In mesh networks, the sender machine is connected to the receiver machine via multiple paths. Efficient transmissions along these paths require proper link choice so as to quickly deliver the packets the destination. Poor link selection can lead to overutilization of some links while the other redundant links remain underutilized. Over-utilized links experience heavy congestions under peak hours. The transmission control protocol (TCP) employs congestion control algorithms to prevent transmitters from overloading the network with data. These algorithms include slow start, congestion avoidance, fast retransmit and fast recovery. The slow start algorithm is utilized during the initial communication phase while congestion avoidance, fast retransmit and fast recovery are reactionary algorithms one packet loss is detected. This paper aimed to analyze the behavior of TCP under these congestion control algorithms in wired mesh networks. The dimensions that were used for this analysis included three way handshake, packet loss, duplicate acknowledgements, segment retransmissions, recovery, I/O plots and time-sequence plots. The objective of this study was to practically understand how the TCP protocol detects and handles network congestions in mesh networks. To achieve this objective, an experimental research design was employed. It involved the practical design of experimental setups that were used to collect data that was analyzed to provide an explanation of the TCP congestion control mechanisms. The results obtained indicate that the TCP first carries out a three handshake before data transmission can take place. It was also observed that the receipt of three duplicate acknowledgements is interpreted by TCP to be packet loss caused by network congestion. Moreover, it was established that TCP initiates fast retransmit and fast recovery when packet loss is detected. The contribution of this paper lies in the fact that it provided a practical understanding of how TCP detects and reacts to mesh network congestion, a concept that is critical to network administrators in their quest for packet loss prevention over the TCP architecture. Towards the end of the paper, suggestions for developing better ways of congestion handling in mesh networks by use of round trip times as a basis for adaptive congestion detection and control are elaborated.

“…Infrastructure networks have a central controlling device which is responsible for performing all the functions. Where as in the infrastructure less networks, there present no central controlling device and the nodes itself are responsible for performing the function [2]. Mobile ad hoc network comes under the category of infrastructure less network in which there present no pre existing networks.…”

The present age is the age of science and it is not wrong to that almost everybody depend upon science for almost everything. The wide use of wireless network and the various hand held devices increase their importance which results in the popularity of ad hoc network. MANET consists of various mobile nodes that communicate with each other. The reason for congestion in a mobile ad hoc network is not only congestion loss can take place due to various reasons which are BER, multipath routing, other attacks and so on. In this paper the study of various TCP variants has been done which are compared and analyzed on the basis of end to end delay parameter.. The routing protocols which have been taken are AODV, DSR and DSDV and the variants are TCP, TCP SACK,TCP New Reno, TCP Vegas and TCP Westwood. This comparison is done with the help of simulation in NS-2 and the analysis is done on the basis of end to end delay parameter which shows which variant perform better in respective routing protocols and less delay the variant takes the number of packets reaches its destination which means more data reaches the destination. This analysis also helps in better speed, reliability and congestion control
