无线传感器网络时钟同步算法综述

Survey of time synchronization algorithms in wireless sensor network

介绍了时钟同步算法在无线传感器网络中的应用及特殊需求,并分析了时钟不同步的原因、物理时钟与逻辑时钟的关系,以及影响同步精度的相关因素。对现有的时钟同步算法进行了分类研究,进而提出了一些比较有价值的研究方向。

The application and special requirements of time synchronization algorithm in wireless sensor network were introduced firstly. Then the un-synchronized reason, the relationship of local clock and logical clock, and the facts that impact the clock synchronizing precision were analyzed. Some promising methods deserving further study were proposed based on the classification of the existing clock synchronization algorithms.
