Abstract

This paper presents a new algorithm for synchronization of data from multiple sensors arriving to a mobile phone's Bluetooth interface with possibly unknown and different sampling frequencies. A system that provides feedback signals to an athlete is one example where it is crucial to synchronize data from several wireless sensors; especially sensor nodes use different and unknown sampling rates.
