摘要
作为一项重要的共性支撑技术,时间同步技术在无线传感器网络中尚未得到很好的解决。分析现有网络时间同步技术,然后针对无线传感器网络中时间同步的要求及特性,着重探讨几种典型的无线传感器网络时间同步算法,并对各种算法进行比较分析,最后提出今后的研究方向。
As the important common support technology, the time synchronization technology for the wireless sensor networks is not still best solved. This article first analyses the current network time synchronization technology, then introduces the request and the character of the time synchronization in the wireless sensor networks. This article mainly discusses the existing typical time synchronization algorithms explicitly designed and proposed for sensor networks,finally compares and analyses these synchronization methods,and indicates the research directions in the future.
