An Introduction to Wireless Acoustic Sensor Networks and Its Applications

Wireless acoustic sensor networks (WASNs) or Wireless microphone networks are a future enhanced technology for acoustic data acquirement and processing. Conventional microphones pick up the audio for processing from huge distances from the source. But WASNs cover a large area of interest and can pick up the audio near to the source. The applications of WASNs are inclusive but not conclusive to underwater wireless Acoustics applications, environmental pollution monitoring and smart city using loT, etc. This paper gives an overview of applications using WASNs and the challenges in implementing the same.
