Acoustic source localization for modelling swarm intelligence of Japanese tree frog

Automated measuring of spatio-temporal data of animal activity

Observation is essential for creating the mathematical model of animal behavior. Such mathematical models inspired from biological mechanisms helps to lead robust and adaptive systems in the ICT field. We focus on the call of animals and try to create the system for acoustic source localization. Many localization techniques have been proposed so far, but most of them are based on the assumption that targets had a transmitter or a receiver of the radio signal. In the case of finding creatures, therefore, those techniques cannot be simply applied. We implement an acoustic localization system using wireless sensor networks whose node has a microphone and conduct experiments in an actual environment.
