Hierarchical underwater acoustic sensor networks [PDF]
Proceedings of the Fifth ACM International Workshop on UnderWater Networks - WUWNet '10, 2010 We propose a hierarchical underwater acoustic sensor network architecture in which the sensors and the collector stations operate in distinct layers. The hierarchical architecture is motivated by the property of the acoustic underwater transmission medium that for each transmission distance there exists an operating frequency for which the narrowband ...

3D Underwater Sensor Network Localization [PDF]
IEEE Transactions on Mobile Computing, 2009 We transform the 3D underwater sensor network (USN) localization problem into its 2D counterpart by employing sensor depth information and a simple projection technique. We first prove that a nondegenerative projection preserves network localizability.
