ABSTRACT
Positions of sensor nodes are essential information for many UbiComp applications. In this demo, we present an accurate but low-cost 3D localization system based on audible sound. By utilizing the tiny-size MEMS microphone and the high accuracy, lightweight synchronization technology enabled by concurrent transmission flooding (CTF), we developed a tiny and low-cost localization system with centimeter-level accuracy. Our experiment show that this system achieves an average accuracy of 5cm in a 3m × 2m × 6m room.

Self-Localization based on Ambient Signals
We present an approach for the localization of passive nodes in a communication network using ambient radio or sound signals. In our settings, the communication nodes have unknown positions. They do not emit signals for localization and exchange only ...
Localization of mobile users using trajectory matching
MELT '08: Proceedings of the first ACM international workshop on Mobile entity localization and tracking in GPS-less environmentsWe present an algorithm enabling localization of moving wireless devices in an indoor setting. The method uses only RF signal strength and can be implemented without specialized hardware. The mobility of the users is modeled by learning a function ...
High-Accuracy TDOA-Based Localization without Time Synchronization
Localization is of great importance in mobile and wireless network applications. Time Difference of Arrival (TDOA) is one of the widely used localization schemes, in which the target (source) emits a signal and a number of anchors (receivers) record the ...
