Synchronization enhancement of a scale-free highly clustered network

We investigate synchronization of a scale-free highly clustered echo state network with Hindmarsh-Rose equations. A new method, inspired by the connectivity between functional cortical columns, is proposed to improve the network in reservoir and enhance its synchrony. The experimental results show that synchronization can be achieved and kept stable with the increase of nodes. This modified complex network, characterized by nature-growing, preferential attachment, and synchrony, is critical to echo state network, and will help study the synchronization of real large-scale complex systems.
