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 کاملMedium Access for Underwater Acoustic Sensor Networks
The underwater acoustic channel has many fundamentally different properties to the conventional radio-based wireless channel. Communication is changed drastically by acoustic propagation speeds that are five orders of magnitude slower than radio. This, coupled with bandwidth limitations, high transmit energy cost, complex multi-path effects, and high bit-error rates make the issue of medium acc...
متن کاملAcoustic Sensor Networks for Woodpecker Localization
Sensor network technology can revolutionize the study of animal ecology by providing a means of non-intrusive, simultaneous monitoring of interaction among multiple animals. In this paper, we investigate design, analysis, and testing of acoustic arrays for localizing acorn woodpeckers using their vocalizations. 2 Each acoustic array consists of four microphones arranged in a square. All four au...
متن کاملAcoustic Communication in Wireless Sensor Networks
Acoustic communication has been widely used in undersea wireless networks. In this paper, we explore the use of acoustic communication in terrestrial wireless sensor networks. This work does not aim to replace the radio communication which is widely used in wireless sensor networks. Rather, we aim to provide an alternative way of communication among the motes in case that the radio transceiver ...
متن کاملSelf Localization of Acoustic Sensor Networks
We present algorithms for self-localization of a network of sensors. We consider the case when no “anchor” nodes with known locations are present. We use source signals in the scene, also at unknown locations, to estimate time-of-arrival and direction-of-arrival between sources and sensors. These measurements are used to compute maximum likelihood relative calibration solutions, in which sensor...
