Abstract
The phenomena of diversity-induced resonance in an array of coupled bistable systems with small-world connectivity and random time delays are investigated. It is found that the diversity σ of the coupled network in the form of quenched noise can induce a resonant effect in response to external signals. By choosing proper value of the coupling c between elements and the normalized shortcut number p, the resonant behavior of the system is enhanced. The resonance is reduced when the mean delay time ⟨τ⟩ in the system is increased. The resonance can be induced for relatively large ⟨τ⟩ and p.
