The accuracy level achievable with a given synchronization system is straightforwardly related to timestamp accuracy. Therefore, different methods have been proposed in the literature for reducing measurement uncertainty in synchronization systems. However, another important problem is deciding whether a received time information is trustworthy, particularly when timing messages generated by a supposedly...
This paper analyzes the effects on synchronization performances of the accuracy of skew and offset estimates, the short and long-term stability of the unregulated clock, the rate at which timing information is exchanged within the network. The work makes use of a simulated clock based on the state-variable model, for which realistic parameters are obtained from experimental measurements of Allan variance...
