The paper introduces an extremely simple and ultra low-power time synchronization algorithm mainly thought for Body Area Networks. Time synchronization of different sensor nodes represents an important issue for both real-time and off-line data merging applications. The core of this modular approach is a fractional-timer concept, borrowed from the Phase-Locked Loops theory, and a heuristic routine managing the on/off switching of the radio section of the device. Preliminary results are presented proving the benefits in terms of power consumption and improved precision.

Abstract
The paper introduces an extremely simple and ultra low-power time synchronization algorithm mainly thought for Body Area Networks. Time synchronization of different sensor nodes represents an important issue for both real-time and off-line data merging applications. The core of this modular approach is a fractional-timer concept, borrowed from the Phase-Locked Loops theory, and a heuristic routine managing the on/off switching of the radio section of the device. Preliminary results are presented proving the benefits in terms of power consumption and improved precision.File in questo prodotto:
