Synchronizability of dynamical scale-free networks subject to random errors
Jalili, Mahdi - In: Physica A: Statistical Mechanics and its Applications 390 (2011) 23, pp. 4588-4595
In this paper the robustness of network synchronizability against random deletion of nodes, i.e. errors, in dynamical … Laplacian and the order parameter quantifying the degree of phase synchrony were adopted, and the synchronizability robustness …, the robustness of its synchronizability against random removal of nodes declines, i.e. the more the number of randomly …

Diffusion processes on complex networks
Švarcová, Natálie; Švarc, Petr - 2009
In this paper we apply agent-based methodology on an issue that is fundamental for economic prosperity and growth: the diffusion of innovations. The diffusion of innovations is one of the topics where agent-based simulation is an extremely fruitful method allowing not only the observation of...

Weighted Fractal Networks
Carletti, Timoteo; Righi, Simone - In: Physica A: Statistical Mechanics and its Applications 389 (2010) 10, pp. 2134-2142
In this paper we define a new class of weighted complex networks sharing several properties with fractal sets, and whose topology can be completely analytically characterized in terms of the involved parameters and of the fractal dimension. General networks with fractal or hierarchical...

Local-world evolving networks with tunable clustering
Zhang, Zhongzhi; Rong, Lili; Wang, Bing; Zhou, Shuigeng; … - In: Physica A: Statistical Mechanics and its Applications 380 (2007) C, pp. 639-650
We propose an extended local-world evolving network model including a triad formation (TF) step. In the process of network evolution, random fluctuation in the number of new edges is involved. We derive analytical expressions for degree distribution, clustering coefficient and average path...

A Complex Network Analysis of the Weighted Graph of the Web2.0 Service Network
Kim, Kibae; Altmann, Jorn - Technology Management, Economics and Policy Program … - 2011
Service providers that own Web2.0 services allow Internet users not only to access their Web2.0 services but also to create new Web2.0 services (mashups) based on theirs. This creation of mashups generates the Web2.0 service network, in which a node represents a Web2.0 service and a link between...

Deterministic weighted scale-free small-world networks
Zhang, Yichao; Zhang, Zhongzhi; Zhou, Shuigeng; Guan, Jihong - In: Physica A: Statistical Mechanics and its Applications 389 (2010) 16, pp. 3316-3324
We propose a deterministic weighted scale-free small-world model for considering pseudofractal web with the co-evolution of topology and weight. Considering the fluctuations in traffic flow constitute a main reason for congestion of packet delivery and poor performance of communication networks,...

A general geometric growth model for pseudofractal scale-free web
Zhang, Zhongzhi; Rong, Lili; Zhou, Shuigeng - In: Physica A: Statistical Mechanics and its Applications 377 (2007) 1, pp. 329-339
We propose a general geometric growth model for pseudofractal scale-free web (PSW), which is controlled by two tunable parameters. We derive exactly the main characteristics of the networks: degree distribution, second moment of degree distribution, degree correlations, distribution of...

High-dimensional random Apollonian networks
Zhang, Zhongzhi; Rong, Lili; Comellas, Francesc - In: Physica A: Statistical Mechanics and its Applications 364 (2006) C, pp. 610-618
We propose a simple algorithm which produces a new category of networks, high-dimensional random Apollonian networks, with small-world and scale-free characteristics. We derive analytical expressions for their degree distributions and clustering coefficients which are determined by the dimension...
