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 ...

Cooperative Authentication in Underwater Acoustic Sensor Networks [PDF]
IEEE Transactions on Wireless Communications, 2019 With the growing use of underwater acoustic communications (UWAC) for both industrial and military operations, there is a need to ensure communication security. A particular challenge is represented by underwater acoustic networks (UWANs), which are often left unattended over long periods of time. Currently, due to physical and performance limitations,

A Reverse Localization Scheme for Underwater Acoustic Sensor Networks [PDF]
Sensors, 2012 Underwater Wireless Sensor Networks (UWSNs) provide new opportunities to observe and predict the behavior of aquatic environments. In some applications like target tracking or disaster prevention, sensed data is meaningless without location information. In this paper, we propose a novel 3D centralized, localization scheme for mobile underwater wireless

Localization with a Mobile Beacon in Underwater Acoustic Sensor Networks [PDF]
Sensors, 2012 Localization is one of the most important issues associated with underwater acoustic sensor networks, especially when sensor nodes are randomly deployed. Given that it is difficult to deploy beacon nodes at predetermined locations, localization schemes with a mobile beacon on the sea surface or along the planned path are inherently convenient, accurate,
