Full-duplex underwater networking

Abstract

This thesis focuses on developing a full-duplex underwater acoustic network and in developing a new protocol utilizing demand assigned multiple access (DAMA) and frequency division multiple access code (FDMA). This new protocol will be utilized to expand networking capabilities in an underwater environment. A benefit of advancements in this area includes fiscal savings and optimization of bandwidth usage creating an increased rate of data transfer. The research conducted in establishing a full-duplex UAN using FDMA will put the Naval Postgraduate School at the forefront of UAN technology and make a significant contribution to understanding underwater networking, the benefits of full-duplex underwater networking, and full-duplex underwater networking using DAMA. These solutions will increase the efficiency and reliability of underwater data transfer and in turn, could be used for further research or as a stepping stone towards improved monitoring of oceanographic anomalies and littoral waters.
