摘要：为了实现无线传感器网络节点的有效时间同步，采用了OMNeT++仿真工具，并改进了TPSN算法，提出了一种无线传感器网络节点周期性休眠时间同步算法。算法分为发现及收集子节点信息和节点同步两个阶段，实现了对无线传感器网络节点的实时精确时间同步。仿真结果表明，该时间同步算法能实现对网络节点十分准确的同步。

Abstract: Aiming at achieving the effective time synchronization in wireless sensor network node, OMNeT++ simulation tools were used, and TPSN algorithm was improved, a wireless sensor network nodes periodically sleep time synchronization algorithm was divided into discovery and collection of child nodes of information and nodes synchronize. Wireless sensor network nodes were realized in real-time precision time synchronization. The simulation results show that the time synchronization algorithm can achieve very accurate synchronization of network nodes.
