Software Acoustic Modems for Underwater Sensor Networks
Recent technological improvements and application opportunities have fueled increased interest in the development and deployment of underwater acoustic sensor networks. Deployment efforts have been impeded by the prohibitive monetary cost and high power consumption of existing acoustic hardware. Alternately, we propose underwater networks that rely on widely available speakers and microphones i...
متن کاملShort Paper: Hierarchical Underwater Acoustic Sensor Networks
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 signal-to-noise ratio is maximized. The sens...
متن کاملPositioning Issues in Underwater Acoustic Sensor Networks
In this paper we discuss challenging issues related to positioning in underwater acoustic networks focussing in the major goal of establishing a common coordinate system which should allow applications to perform collaborative sensing tasks such as identification, detection, and/or tracking of sea targets. A general description of the most important positioning methods and algorithms which have...
متن کاملSoftware Driven Underwater Acoustic Sensor Networks
Deployment efforts of underwater acoustic sensor networks have been impeded by the prohibitive monetary cost and high power consumption of existing acoustic hardware, which typically targets deep water long range communication. To address this issue, we propose software-driven underwater networks that rely on widely available speakers and microphones in electronic devices, coupled with software...
متن کاملUnderwater acoustic sensor networks: research challenges
Underwater sensor nodes will find applications in oceanographic data collection, pollution monitoring, offshore exploration, disaster prevention, assisted navigation and tactical surveillance applications. Moreover, unmanned or autonomous underwater vehicles (UUVs, AUVs), equipped with sensors, will enable the exploration of natural undersea resources and gathering of scientific data in collabo...
