Distributed classification of acoustic targets in wireless audio-sensor networks
Computer Networks, 2008Target tracking is an important application for wireless sensor networks. One important aspect of tracking is target classification. Classification helps in selecting particular target(s) of interest. In this paper, we address the problem of classification of moving ground vehicles.

Simplified acoustic localization by linear arrays for wireless sensor networks
2013 18th International Conference on Digital Signal Processing (DSP), 2013The application of wireless sensor networks (WSN) for the task of acoustic localization provides great opportunities for distributed cooperative tracking of sound sources in large areas. However WSNs are significantly more limited in terms of computational resources and power than typical computer systems.

Acoustic event localization on an Arduino-based wireless sensor network
2014 IEEE Latin-America Conference on Communications (LATINCOM), 2014Valuable information from acoustic signals has not been fully considered into real applications associated with assisting people. In fact, the assessment of acoustic signals as an input parameter for localization techniques has useful applications in detecting the presence of living beings trapped in emergency situations by processing any type of sound

Refracted Acoustic Communications in Wireless Underwater Sensor Networks with Mobility
Proceedings of the 4th International Conference on Sensor Networks, 2015Routing is a fundamental function of any wireless network. For battery-powered underwater sensors using acoustic waves, routing is even more challenging due to an ever changing and communication-opaque ocean. Herein, we propose a shallow-water routing scheme that adapts to a unique physical phenomena of the medium.

Mobile phone based acoustic localization for wireless sensor networks
2015 IEEE 2nd World Forum on Internet of Things (WF-IoT), 2015In wireless sensor networks, localization techniques are required for finding physical location of the sensor nodes. Most of the existing 2D and 3D localization schemes are reference based. Finding physical locations of sensor nodes in an application field with only 2D or 3D physical topology map or logical topology map is arduous and tedious.

The Gaussian Processes for Acoustic Localisation and Tracking in Wireless Sensor Network
5th International Conference on Imaging for Crime Detection and Prevention (ICDP 2013), 2013In this paper, the problem of enhancing the robustness of acoustic source localisation and tracking based on Time Delay of Arrival (TDOA) in wireless sensors networks (WSN) is considered. Distributed acoustic localisation is used relying on the sensing and the communication specification of the motes.
