Acoustic Sensor Network Self-Localization: Experimental Results
نویسنده
چکیده
In this paper we present experimental results on propagation, coherence, and time delay estimation (TDE) in an acoustic microphone array. The primary goal is to understand the achievable accuracy of acoustic TDE using low-cost, commercial off the shelf (COTS) speakers and microphones. In addition, the experiment seeks to provide an empirical understanding of the effects of center frequency, bandwidth, and signal duration on TDE effectiveness. As part of this study, limited empirical signal propagation characteristics were obtained using this COTS equipment.

متن کاملExperimental Results for and Theoretical Analysis of a Self-Organizing Global Coordinate System for Ad Hoc Sensor Networks
We demonstrate that it is possible to achieve robust and reasonably accurate localization in a randomly placed wireless sensor network composed of inexpensive components of limited accuracy. We present an algorithm for creating an accurate local coordinate system, aligned with the global coordinates, without the use of global control, globally accessible beacon signals, or accurate estimates of...

Heterogeneous wireless sensor networks consist of some different types of sensor nodes deployed in a particular area. Different sensor types can measure different quantity of a source and using the combination of different measurement techniques, the minimum number of necessary sensors is reduced in localization problems. In this paper, we focus on the single source localization in a heterogene...
