A Survey: variants of TCP in Ad-hoc networks

MANET (Mobile Ad-hoc network) forms a temporary network of wireless mobile nodes without any infrastructure where all nodes are allowed to move freely, configure themselves andinterconnect with its neighbors to perform peer to peer communication and transmission. TCP (Transmission ControlProtocol) offers reliable, oriented connection and mechanism of end to end delivery. This article provides the review and comparison of existing variants of TCP for instance: The TCP Tahoe, The TCP Reno, The TCP New Reno, The Lite, The Sack, The TCP Vegas, Westwood and The TCP Fack. TCP’sperformance depends on the type of its variants due to missing of congestion control or improper activation procedures suchas Slow Start, Fast Retransmission, and Congestion Avoidance,Retransmission, Fast Recovery, Selective Acknowledgement mechanism and Congestion Control. This analysis is essential to be aware about a better TCP implementation for a specific scenario and then nominated a suitable one.
