Abstract: According to the features of Wireless Industrial Control Networks（WICN），the shortage of some familiar time synchronization such as RBS and TPSN are analyzed.Wireless Industrial Control Networks Time Synchronization（WICNTS） algorithm is proposed to suit the WICN based on token control MAC protocol.It utilizes the MAC layer sign timestamp to make pair time synchronization，then establishes the process of model and makes a simulation trial with the protocol by use of OMNET++ concrete event simulation platform.The results demonstrate that the protocol meets the time synchronization requirement of wireless industrial control networks.

摘要： 针对无线工业控制网络WICN的特点，分析RBS和TPSN时间同步算法的不足。利用基于令牌的MAC协议，提出一种适用于无线工业控制网的时间同步算法WICNTS，该算法采用MAC层记录时戳的方式进行成对同步。然后给出了模型的建立过程，并用离散事件仿真平台OMNeT++对该协议进行仿真实验，仿真结果表明该算法能满足WICN网络的时间同步要求。
