There exists an increasing demand for reliable, high capacity Underwater Acoustic Networks (UANs), as evidenced by the large volume of paper invested over the last decade in overcoming the difficulties inherent with propagation of information bearing signals through shallow water regions. Three key factors affect the data transfer capacity of the network are transmit power, which requires a trade-off between node battery or power cell life expectancy and signal propagation range, bandwidth availability, which restricts data rate and the number of coexisting channels, and propagation delay, which introduces communication latency. Application interests include oceanographic information gathering, environmental monitoring, drilling, offshore mining or coastal defense (anti-submarine and mine/counter-mine warfare). The aim of this paper is the development of a networking module that can cope with the adverse underwater communications environment and still meet all the application requirements.
