A new distributed algorithm of clock synchronization for static sensor networks

Abstract

In this paper, a new distributed algorithm is presented to achieve the consensus of time variations and that of initial time simultaneously. By combining both controller and estimator design methods, it obtains higher synchronization precision with stronger robustness against noisy inputs resulted from crystal oscillators. Furthermore, the control input is ensured bounded to make our algorithm realizable in practical implementation. The implementation of the algorithm allows the receiving end to be event-triggered, while the transmitting end is executed periodically. The performance of the algorithm is illustrated by the given numerical simulations.
