Abstract

Stochastic resonance (SR) of a coupled array of bistable oscillators with small-world connectivity is numerically studied. At certain coupling strength, it is found that both temporal SR and spatial synchronization of the oscillators can be considerably improved by increasing the order of randomness of the network due to the long-range couplings. Moreover, our results show that a small fraction of long-range couplings is sufficient to obtain great improvement in SR and synchronization.
