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 ...
