Abstract

We study aperiodic stochastic resonant data storage in an extended system evolving on directed small-world networks. Each node of the network represents a dynamical bistable system, and nodes are randomly connected by the directed shortcuts with a rewiring probability. The constructive role of the internal noise and the random connectivity is characterized by the bit error rate and demonstrated in numerical simulations. Random internal noise in each node enhances the survival of a short-time length of binary signal via aperiodic stochastic resonance. Interestingly, random connectivity further improves the propagation time of binary information through the small-world architecture.
