Summary:
We investigate performance of a novel synchronization scheme, which does not require any signal exchange between the devices. This synchronization scheme is based on noise-induced synchronization phenomenon, that the phase difference of nonlinear limit cycle oscillators are synchronized by adding common noise to each of them. Our natural synchronization scheme uses natural environmental noise as the input noise to each oscillator, which is mounted in the devices. Those oscillators can be synchronized in some cases while the noise fluctuations measured at the neighboring devices are similar. In this paper, we investigate the feasibility of the proposed synchronization scheme using environmental electromagnetic waves. Our experiments result show that the nonlinear limit cycle oscillators can be synchronized by the environmental electromagnetic waves. We also investigate the feasibility of the proposed scheme implemented on the wireless sensor network devices. Our experiments show that the independent devices can be synchronized by the natural environmental fluctuations.
