Summary
The positive-feedback preference (PFP) model accurately replicates complex internet topology, revealing how network evolution mechanisms generate diverse structural properties and their correlations.
Area of Science:
- Complex Networks
- Internet Topology
- Network Science
Background:
- The internet exhibits highly complex structural properties.
- Existing models struggle to capture the full range of internet topology characteristics.
- The positive-feedback preference (PFP) model was developed to generate realistic internet topologies.
Purpose of the Study:
