Research on a Real-Time Fault Tolerant Time Synchronization Algorithm for GSM-R Wireless Sensor Networks Based on Network Materials
Time synchronization is a key technology in wireless sensor networks. In this paper, aim at high-speed railway GSM-R network require higher real time, fault tolerance and band coverage way, presents a real-time fault-tolerant wireless sensor network time synchronization algorithm, using direct forwarding strategy, regression analysis and abnormal data filtering methods to meet the requirements of GSM-R network. Analysis and simulation show that the algorithm has good real-time and fault tolerance to meet the requirements of GSM-R network applications.
