IEEE 1588 for Clock Synchronization in Industrial IoT and Related Applications: A Review on Contributing Technologies, Protocols and Enhancement Methodologies

Abstract: Precise time synchronization becomes a vital constituent due to the rigorous needs of several time-sensitive applications. The clock synchronization protocol is one of the fundamental factors that can define the quality of communication. Our study starts with a brief discussion on the application domain of precise time synchronization and comes with an in-depth study of the synchronization with the main focus on the IEEE 1588 Precision Time Protocol (PTP). We have compared the well-known synchronization techni… Show more

“…This will enhance the learning process for diverse industrial devices, resulting in an intelligent IIoT network with reduced computing complexity and increased network lifetime. The best example is the employment of a hardware-in-the-loop (HIL) simulation platform [172][173][174][175][176]. The HIL combines computations for numerous processes with the internal hardware of sensors and actuators.…”

“…When multiple slaves are present in a network, peer delay packets are only sent to the nearest node, not all the way upstream to the master. Lastly, if the network is suddenly changed due to a fault or similar, recovery time is reduced as not all delay calculations will be affected [22].…”

“…The nodes in the network use their local clocks to determine the position of the time slot. Even if these local clocks use crystal oscillators with the same frequency, the time error of the crystal oscillator will occur due to the instability of their own operating state and the influence of external environmental factors, which will also cause a time offset between their local clocks [2]. Therefore, a clock synchronization mechanism is necessary to make the time of each node the same.…”
