摘要 时间同步作为无线传感器网络应用的一项支撑技术,对无线传感器网络的设计和应用都很关键.在满足无线传感器网络时间同步精度要求的前提下,应尽可能节约能源,在对现有的时间同步机制进行分析研究的基础上,给出了一种改进的TPSN时间同步算法.并利用网络仿真器NS2对改进的算法进行仿真验证,取得了满意的结果. Time synchronization is a fundamental service for both design and application of wire- less sensor networks. In order to meet the time synchronization accuracy requirement of wireless sensor networks and take account of saving energy, an improved TPSN time synchronization algo- rithm is setup based on the analysis and research of the existing time synchronization mechanism. The improved algorithm has been simulated and verified in network simulator NS2, and obtained a satisfactory result.
