Abstract
As various applications require concrete knowledge about the position
of objects, different methods for localization exist. Unfortunately,
most off the shelf methods lack precision or are not applicable
indoors. In this paper we present SNoW Bat, a full featured
decentralized ultrasonic system for three dimensional localization and
tracking of mobile objects. SNoW Bat is a sensor net solution
supporting self-configuration for easy deployment, robustness for fault
tolerance and simultaneous monitoring of several objects for increased
scalability. Applied techniques and results will be discussed in detail
allowing a brief comparison to similar systems available.
