Abstract: This paper presents a new algorithm for application layer synchronisation of data from multiple sensors arriving to a mobile phone's Bluetooth interface. A system that provides feedback signals to an athlete is one example where it is crucial to synchronise data from several wireless sensors. This paper also discusses synchronisation problems caused by unpredictable Bluetooth transmission performance.

Keywords: multi-sensor data synchronisation; data fusion; wireless sensor networks; WSNs; mobile phones; Bluetooth; multiple sensors; athlete feedback; training monitoring; performance monitoring; kinematic performance; kinetic performance; athletes.
