Summary:
Noise-induced synchronization is a phenomenon that uncoupled nonlinear oscillators synchronize by adding common noise. We have proposed a new synchronization method using the cross-correlated natural environment data instead of a common input noise. Wireless devices obtain environmental data by their own sensors, and input these data independently. Based on noise-induced synchronization theory, nonlinear oscillators running in wireless devices are synchronized without any interaction or communications. In our implementation, devices use time average values of the environmental data as an input noise. There is interval of noise input because devices calculate time average of obtained data independently. Therefore, the timing of inputting noise is different among devices. In this paper, we propose a novel data input method, that adjusts data input interval to achieve synchronization of timing of input between devices. We use time series of Rossler system as input data in our numerical simulation. Our proposed scheme minimize different of input timing among two FitzHugh-Nagumo oscillators by adding time series of Rossler system at some specific phases.
