Acoustic Source Localization in Wireless Sensor Networks: Model and Numerical Algorithm
Abstract: Jianhua Yuan will present a series of techniques, based upon the energy based acoustic features, to locate a sound source given measurements of the sound field. For wireless ad hoc sensor network applications, energy based acoustic features is an appropriate choice since the acoustic power emitted by targets, such as moving vehicles usually varies slowly with respect to time. In this approach, mathematical models and new numerical methods may be used to yield higher accuracy in terms of source location estimates compared to the earlier method.
