N2 - This paper presents a novel clock synchronization algorithm based on the Transparent Clock mechanism of peer-to-peer Precision Time Protocol. To model the dynamics of the oscillator and the influence of the uncertainties, e.g., random stamping and quantization errors, on the synchronization performance, clock synchronization is formulated as a probabilistic inference problem which can be solved by a distributed hidden state estimation method such as the sum-product algorithm. The performance of this approach is verified by numerical results.
