The objective of this master thesis is to describe the problems of the
underwater acoustic sensor network and make some experiments. The
experiments carried out try to characterize the communication in underwater
environments in order to be able to develop underwater sensor networks. In
the first chapter we describe the motivations, features of aquatic environment,
the difficulties of underwater acoustic channels, and the open questions in
mobile underwater sensor network design. In the second chapter we try to
describe the experiments, show the results and try to explain these results.
And finally in the third chapter we explain the conclusions and the further works
of this master thesis.
