Abstract: Data transmission in Underwater Wireless Sensor Networks (UWSNs) is one of the key enablers used in technologies for future ocean-monitoring systems and other underwater applications. The use of acoustic waves in UWSNs suffer from a high propagation delay, as well as a limited available bandwidth due to the high-noise level, making the use of the different traditional existing protocols a major challenge in this environment. In this paper, we have chosen two TCP mechanisms already defined: TCP Vegas and TCP New Reno, to evaluate the effects of variable TCP packet size and TCP connection density in a subsea network under two common routing protocols, namely AODV and DSDV. The simulation results show that the performances of the two TCPs using DSDV routing protocol provide a more efficient result than those using the AODV routing protocol and that New Reno TCP gives better results than Vegas TCP in the UWSNs.
