A Nonlinear Model for Time Synchronization
This addresses the need for more efficient and less frequent synchronization in time-sensitive systems, though it appears incremental as it builds on existing linear models.
The paper tackles the problem of clock frequency drift in time synchronization by introducing a nonlinear model that more accurately captures frequency shifts, allowing for longer intervals between synchronizations and improved performance compared to linear methods like PTP.
The current algorithms are based on linear model, for example, Precision Time Protocol (PTP) which requires frequent synchronization in order to handle the effects of clock frequency drift. This paper introduces a nonlinear approach to clock time synchronize. This approach can accurately model the frequency shift. Therefore, the required time interval to synchronize clocks can be longer. Meanwhile, it also offers better performance and relaxes the synchronization process. The idea of the nonlinear algorithm and some numerical examples will be presented in this paper in detail.
