Mobile Ad-Hoc Network is an autonomous group of mobile users that communicate using wireless links with no support from any pre-existing infrastructure network and used as a highly reliable end-to-end protocol for transporting applications. In this paper evaluate the performance of the four TCP variants (New Reno, SACK, TCP TAHOE and VEGAS) under a variety of network conditions. The simulations results reveal that out of the four, the SACK variant can adapt relatively well to the changing network sizes while the VEGAS performs most robustly in different node density scenarios. On the other hand, the research asserts the fact of superiority of, reactive protocol over proactive protocol when routing the same traffic in the network. Nonetheless, among the reactive protocols AODV performance (in the presence of a high mobility) has been found to be remarkable.
