This study explores evolving networks where new nodes form links based on preferred distances. The shortest distance rule creates scale-free network properties, but other network characteristics differ significantly.

Area of Science:

  • Network Science
  • Complex Systems
  • Computational Social Science

Background:

  • Understanding the structure and evolution of complex networks is crucial.
  • Existing models like random and scale-free networks have limitations in capturing real-world network dynamics.
  • Evolving networks with preferential attachment rules require further investigation.

Purpose of the Study:

  • To investigate network evolution by introducing preferred distance rules for new node attachments.
  • To analyze how different distance preferences impact key network topological parameters.
  • To compare the emergent network properties with those of random and scale-free networks.

Main Methods:

  • Simulating network growth with varying distance preference rules.

  • Calculating network parameters: graph Laplacian's first eigenvalue (synchronizability), clustering coefficients, average distances, and degree distributions.
  • Comparative analysis against benchmark random and scale-free network models.

    • Main Results:

    • The shortest distance preference rule generates a power-law degree distribution, similar to scale-free networks.
    • Other network parameters, particularly the clustering coefficient, show significant deviations from scale-free networks.
    • Varying distance preferences lead to distinct network topological characteristics.

    Conclusions:

    • The shortest distance attachment rule can lead to scale-free degree distributions but does not replicate all scale-free network properties.
    • Network evolution models incorporating distance preferences offer a nuanced perspective on network topology.
    • Further research can explore the implications of these findings for network function and resilience.
