Network topology optimization by turning non-scale-free networks into scale-free networks using nonlinear preferential rewiring method

open access: yesInternational Journal of Distributed Sensor Networks, 2018
In practical application, the generation and evolution of many real networks always do not follow rigorous mathematical model, making network topology optimization a great challenge in the field of complex networks.

Classification of scale-free networks [PDF]

open access: yesProceedings of the National Academy of Sciences, 2002
While the emergence of a power-law degree distribution in complex networks is intriguing, the degree exponent is not universal. Here we show that the betweenness centrality displays a power-law distribution with an exponent η, which is robust, and use it to classify the scale-free networks.

Robustness of preferential-attachment graphs

open access: yesApplied Network Science, 2023
The widely used characterization of scale-free networks as “robust-yet-fragile” originates primarily from experiments on instances generated by preferential attachment.

Polygon-Based Hierarchical Planar Networks Based on Generalized Apollonian Construction

open access: yesPhysics, 2021
Experimentally observed complex networks are often scale-free, small-world and have an unexpectedly large number of small cycles. An Apollonian network is one notable example of a model network simultaneously having all three of these properties.

Scale-free network of earthquakes [PDF]

open access: yesEurophysics Letters (EPL), 2004
The district of southern California and Japan are divided into small cubic cells, each of which is regarded as a vertex of a graph if earthquakes occur therein. Two successive earthquakes define an edge and a loop, which replace the complex fault-fault interaction. In this way, the seismic data are mapped to a random graph.

Synchronization in interacting Scale Free Networks [PDF]

open access: yes, 2015
We study the fluctuations of the interface, in the steady state, of the Surface Relaxation Model (SRM) in two scale free interacting networks where a fraction $q$ of nodes in both networks interact one to one through external connections. We find that as

Simulation of scale-free networks [PDF]

open access: yesProceedings of the Second International ICST Conference on Simulation Tools and Techniques, 2009
In this paper, we present a new simulation tool for scale-free networks composed of a high number of nodes. The tool, based on discrete-event simulation, enables the definition of scale-free networks composed of heterogeneous nodes and complex application-level protocols.

Highly clustered scale-free networks [PDF]

open access: yesPhysical Review E, 2002
We propose a model for growing networks based on a finite memory of the nodes. The model shows stylized features of real-world networks: power law distribution of degree, linear preferential attachment of new links and a negative correlation between the age of a node and its link attachment rate.

Are scale-free networks robust to measurement errors?

open access: yesBMC Bioinformatics, 2005
Background Many complex random networks have been found to be scale-free. Existing literature on scale-free networks has rarely considered potential false positive and false negative links in the observed networks, especially in biological networks ...

Geographical Embedding of Scale-Free Networks [PDF]

open access: yes, 2003
A method for embedding graphs in Euclidean space is suggested. The method connects nodes to their geographically closest neighbors and economizes on the total physical length of links.
