Abstract: | In weighted networks, redistribution of link weights can
effectively change the properties of networks, even though the corresponding binary topology remains unchanged. In this paper,
the effects of weight randomization on synchronization of coupled chaotic maps is investigated on regular weighted networks.
The results reveal that synchronizability is enhanced by redistributing of link weights, i.e. coupled maps reach complete
synchronization with lower cost. Furthermore, we show numerically that the
heterogeneity of link weights could improve the complete synchronization on regular weighted networks. |
