We developed a decoupling process for scale-free networks to improve synchronization while maintaining network structure. This method enhances network synchronizability, with maximum vertex betweenness showing the strongest correlation.

Area of Science:

  • Network Science
  • Complex Systems
  • Synchronization Dynamics

Background:

  • Scale-free networks are prevalent in nature and technology.
  • Network synchronizability is crucial for collective behaviors.
  • Existing methods may alter network structure.

Purpose of the Study:

  • To introduce a decoupling process for enhancing network synchronizability.
  • To preserve the scale-free structure during synchronization enhancement.
  • To identify key structural properties correlated with synchronizability.

Main Methods:

  • Implementing a decoupling process on scale-free networks.
  • Analyzing the eigenratio of the coupling matrix to measure synchronizability.
  • Correlating structural properties (e.g., vertex betweenness) with synchronization.

Main Results:

  • The decoupling process significantly enhances network synchronizability.
  • The scale-free network structure is preserved post-decoupling.
  • Maximum vertex betweenness emerged as the most influential structural feature for synchronizability.

Conclusions:

  • Decoupling is an effective strategy for improving network synchronizability.
  • Synchronization dynamics are linked to information transmission and traffic flow.
  • The proposed method offers a low-cost approach for network modification with potential applications.
