—We present a MAC protocol for underwater acoustic sensor networks (UASN) able to overcome the shortcomings induced by the temporary presence of noise sources within, or close-by, the region covered by the UASN. Our solution, named NAMAC for Noise-aware MAC protocol, exploits the ability of nodes equipped with multi-band modems to rapidly switch the(More)
We propose a technique to jointly characterize the power spectral density of the noise produced by a ship and the nominal sound propagation parameters (attenuation exponent and absorption coefficient) for each frequency value, over an area of interest. The technique uses a set of properly displaced recording stations and AIS data. Our preliminary results(More)
