Abstract
In this paper, we give a brief introduction to the sensor synchronization problem, highlight how the choice of hardware affects what synchronization methods can be applied, and present our ongoing research on sensor synchronization. Our work is based on estimating timestamps on the host processor, using a method suitable for mobile phones and other low-cost consumer grade devices since it does not require special hardware support. We also describe an experiment to measure sensor synchronization performance using a simple calibration rig. Our initial results show that the estimated timestamps provide a stable synchronization and a clear improvement in synchronization accuracy compared to the direct method of using sample arrival times as timestamps.
