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
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 
in the system is increased. The resonance
can be induced for relatively large and p.
