Title: | Acoustic source localization in wireless sensor network | Authors: | Saric Z. Kukolj, Dragan Teslic N. |
Issue Date: | 1-Oct-2010 | Journal: | Circuits, Systems, and Signal Processing | Abstract: | In this paper, we consider the problem of acoustic source localization in a wireless sensor network based on different measured signal quantities, such as the received signal strength (RSS), the angle of arrival (AOA) and the time of arrival (TOA). For each of these quantities, an appropriate weighted least squares criterion function is developed to be used for sound source localization. The weights of each criterion function take into account the decrease in the signal-to-noise ratio (SNR) with distance from the source. In addition, RSS localization algorithm proposed in this paper provides improvement of the localization accuracy for low SNR. Finally, separate criterion functions for RSS, TOA and AOA are used together to obtain minimal localization error and maximal reliability of the acoustic source localization. Simulation analysis confirms improved performance of the proposed localization algorithm. © Springer Science+Business Media, LLC 2010. | URI: | https://open.uns.ac.rs/handle/123456789/10811 | ISSN: | 0278081X | DOI: | 10.1007/s00034-010-9187-3 |
