Rate-Constrained Noise Reduction in Wireless Acoustic Sensor Networks

IEEE/ACM Transactions on Audio, Speech, and Language Processing, 2020
Wireless acoustic sensor networks (WASNs) can be used for centralized multi-microphone noise reduction, where the processing is done in a fusion center (FC). To perform the noise reduction, the data needs to be transmitted to the FC. Considering the limited battery life of the devices in a WASN, the total data rate at which the FC can communicate with ...

An efficient scalable scheduling mac protocol for underwater sensor networks [PDF]

, 2018
Underwater Sensor Networks (UWSNs) utilise acoustic waves with comparatively lower loss and longer range than those of electromagnetic waves. However, energy remains a challenging issue in addition to long latency, high bit error rate, and limited ...

Acoustic Monitoring System Using Wireless Sensor Networks

Procedia Engineering, 2012
AbstractIn this paper, an acoustic monitoring system is developed to address the issue and limitations of large volume sampling. IRIS and MICAz sensor motes are used to realize the hardware requirements of the WSN and the acquired data were processed. Multi-hop capability of the mesh network is also implemented.

A survey of localization in wireless sensor network [PDF]

, 2012
Localization is one of the key techniques in wireless sensor network. The location estimation methods can be classified into target/source localization and node self-localization. In target localization, we mainly introduce the energy-based method.

The Citizen as a Key Point of the Policies: A First Approach to Auralization for the Acoustic Perception of Noise in an Urban Environment

Proceedings, 2019
The improvement of the quality of life in the framework of the smart city paradigm cannot be limited to a set of objective measures carried out over several critical parameters (e.g., noise, air pollution).
