Abstract

With the rapid advancement of Industrial Internet of Things (IIoT) technology, clock synchronization plays a vital role in network operations, particularly in time-sensitive networks (TSN) industrial systems. Clock drift in these networks can severely compromise data transmission timeliness and accuracy. This study proposes an effective clock synchronization drift suppression method that enhances existing algorithms through precise synchronization techniques, effectively reducing drift caused by network latency and jitter. Experimental results demonstrate that the proposed approach significantly improves clock synchronization accuracy while ensuring stability and real-time performance of Industrial IoT systems in dynamic environments.
