Time synchronization in wireless industrial control networks

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.
