Concomitant Skew and Phase Correction (CSPC) for Industry 5.0 Enabler Pervasive Distributed Computing Systems

Synchronizing time among pervasive distributed computing nodes is critical and also a key enabler for proper functioning and coordination in an Industry 5.0 environment. It enables distributed data logging, coordination of distributed algorithms, and event driven interactions in a synchronized manner which is not possible without having a common notion of time in an Industry 5.0 environment. Synchronization ensures that data generated by pervasive nodes is consistent and accurate. Diverse synchronization methods are available, however, these existing methods use multiple timestamp exchanges for correction of clock skew. Concomitant Skew and Phase Correction (CSPC) method proposed in this article uses Phase Embedded and Skew Estimated Timestamp (PESET). In contrary to existing methods, single PESET is sufficient to compute clock skew offset along with phase offset at the receiving node. The experimental results also validate single PESET can be used instead of multiple timestamp exchanges in low latency Industry 5.0 environments. This does not only lead to save the computational resources of the Industry 5.0 environments, also enable them as energy efficient networks.
