Acoustic source localizer using wireless sensor networks

2017 CHILEAN Conference on Electrical, Electronics Engineering, Information and Communication Technologies (CHILECON), 2017
This work describes the implementation of a wireless sensor network (WSN) to locate an acoustic source in two dimensions. The network is made up of three sensor nodes located at the corners of a right triangle; a fourth node in the vicinity of the array acts as a base station providing connection to a notebook; the acoustic source is assumed to be ...

Shooter localization in wireless acoustic sensor networks

2017 IEEE Symposium on Computers and Communications (ISCC), 2017
This paper introduces a feasibility study of a low cost and power effective wireless acoustic sensor network for shooter localization. Currently deployed sensors for this application use a time domain gunshot signal analysis and high sampling rates, in the order of MS/s.

Audio coding in wireless acoustic sensor networks

Signal Processing, 2015
In this paper, we consider the problem of source coding for a wireless acoustic sensor network where each node in the network makes its own noisy measurement of the sound field, and communicates with other nodes in the network by sending and receiving encoded versions of the measurements.

Acoustic objective recognition in wireless sensor networks

2009 4th IEEE Conference on Industrial Electronics and Applications, 2009
As different types of noises coming from different vehicles and weapons mix together, it is a challenge to identify acoustic objectives in such a noisy situation. A systematical study of acoustic objective recognition in wireless sensor network is conducted in this paper.

Multi-Agent-Based Acoustic Sensor Node Deployment in Underwater Acoustic Wireless Sensor Networks

Journal of Information Technology Research, 2020
The deployment of acoustic sensor nodes in 3-D underwater acoustic wireless sensor networks (UAWSN) is a difficult task due to various aquatic conditions and physical obstacles. This work proposes multi-agent-based acoustic sensor node deployment (MASD) to deploy the acoustic nodes at ideal positions to enhance coverage and seamless connectivity.
