摘要

本文主要介绍了一种用于体域网络的极其简单、超低功耗的时间同步算法。不同传感器节点的时间同步是实时和离线数据合并应用中的一个重要问题。这种模块化方法的核心是一个分数定时器概念,借鉴了锁相环理论,以及一个启发式例程来管理设备无线电部分的开/关开关。初步结果证明了在功耗和精度方面的优势。

A Fractional Approach to Time Synchronization in Wireless Body Area Networks
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.
