U-NewReno transmission control protocol to improve TCP performance in Underwater Wireless Sensors Networks

Advances in the different fields of application on Underwater Wireless Sensor Networks (UWSNs) makes this environment more attractive for researchers and industry. Communication in this environment faces exceptional challenges, since its data transmission is experiencing a limitation in the use of bandwidth, the presence of surrounding noise and also the long delays of acoustic propagation. It is of great benefit to design an adaptive transmission control protocol (TCP) for the underwater environment. In this work, we propose U-New Reno a transmission control protocol suitable for the marine environment wherein we consider both the adaptation of the maximum size of the congestion window and the expiry of the round-trip time (RTT). U-New Reno can achieve a very significant improvement concerning the retrans-mission rate of the packets and the evolution of the number of packets delivered. The performances of both metrics are closely observed during the comparison of simulation results between the standard New Reno and our proposed U-New Reno.(c) 2021 The Authors.
