Abstract
Underwater sensor networks are becoming an important field of research, because of
their everyday increasing application scope. Examples of their application areas are environmental
and pollution monitoring (mainly oil spills), oceanographic data collection, support for submarine
geolocalization, ocean sampling and early tsunamis alert. The challenge of performing underwater
communications is well known, provided that radio signals are useless in this medium, and a wired
solution is too expensive. Therefore, the sensors in these networks transmit their information using
acoustic signals that propagate well under water. This data transmission type not only brings an
opportunity, but also several challenges to the implementation of these networks, e.g., in terms
of energy consumption, data transmission and signal interference. In order to help advance the
knowledge in the design and implementation of these networks for monitoring underwater spaces,
this paper proposes a MAC protocol for acoustic communications between the nodes, based on
a self-organized time division multiple access mechanism. The proposal was evaluated using
simulations of a real monitoring scenario, and the obtained results are highly encouraging.
