A congestion awareness routing strategy for scale-free networks with tunable clustering

Chen, Zhen Yi; Wang, Xiao Fan - In: Physica A: Statistical Mechanics and its Applications 364 (2006) C, pp. 595-602

By incorporating local traffic information into the basic shortest path routing policy, we propose a congestion …-free networks with different clustering coefficients and in different congestion phases. We find that there exists an optimal value … for the tunable parameter in the congestion awareness strategy. Though the optimal value increases slowly as the traffic …

Diophantine networks

Bedogne’, C.; Masucci, A.P.; Rodgers, G.J. - In: Physica A: Statistical Mechanics and its Applications 387 (2008) 8, pp. 2161-2169

We introduce a new class of deterministic networks by associating networks with Diophantine equations, thus relating network topology to algebraic properties. The network is formed by representing integers as vertices and by drawing cliques between M vertices every time that M distinct integers...

A topological pattern of urban street networks: Universality and peculiarity

Jiang, Bin - In: Physica A: Statistical Mechanics and its Applications 384 (2007) 2, pp. 647-655

In this paper, we derive a topological pattern of urban street networks using a large sample (the largest so far to the best of our knowledge) of 40 US cities and a few more from elsewhere of different sizes. It is found that all the topologies of urban street networks based on street–street...

Synchronization of Kuramoto oscillators in random complex networks

Li, Ping; Yi, Zhang - In: Physica A: Statistical Mechanics and its Applications 387 (2008) 7, pp. 1669-1674

We study the synchronization of coupled phase oscillators in random complex networks. The topology of the networks is assumed to be vary over time. Here we mainly study the onset of global phase synchronization when the topology switches rapidly over time. We find that the results are, to some...

Chinese lexical networks: The structure, function and formation

Li, Jianyu; Zhou, Jie; Luo, Xiaoyue; Yang, Zhanxin - In: Physica A: Statistical Mechanics and its Applications 391 (2012) 21, pp. 5254-5263

In this paper Chinese phrases are modeled using complex networks theory. We analyze statistical properties of the networks and find that phrase networks display some important features: not only small world and the power-law distribution, but also hierarchical structure and disassortative...

Scale free distribution in an analytical approach

Takagi, Kosuke - In: Physica A: Statistical Mechanics and its Applications 389 (2010) 10, pp. 2143-2146

In order to explain the scale free feature of complex networks, we introduce an analytical approach for investigating the degree distribution. We represent the degree distribution by the probability density function, where the correspondence between them is given approximately by the...

Scale-free property of directed networks with two intrinsic node weights

Shioda, Shigeo; Nakamura, Kazuhiro - In: Physica A: Statistical Mechanics and its Applications 388 (2009) 15, pp. 3249-3260

This paper proposes a network model to understand the scale-free property of directed networks. The proposed model assigns two intrinsic variables (incoming and outgoing weights) to every node. A directed link is established from node i to node j if the sum of the outgoing weight of node i and...

Epidemic spreading in a finite-precision BA model

Ababou, M.; Vandewalle, N.; Moussa, N.; El Bouziani, M.; … - In: Physica A: Statistical Mechanics and its Applications 390 (2011) 20, pp. 3573-3578

The Barabasi–Albert (BA) model with finite-precision preferential attachment is used to build a wide range of network structures. Spreading epidemics and collective dynamics are investigated on such complex networks. Numerical simulations reveal a transition from an exponential scaling to a...

A network of two-Chinese-character compound words in the Japanese language

Yamamoto, Ken; Yamazaki, Yoshihiro - In: Physica A: Statistical Mechanics and its Applications 388 (2009) 12, pp. 2555-2560

Some statistical properties of a network of two-Chinese-character compound words in the Japanese language are reported. In this network, a node represents a Chinese character and an edge represents a two-Chinese-character compound word. It is found that this network has properties of being...

A new community-based evolving network model

Xie, Zhou; Li, Xiang; Wang, Xiaofan - In: Physica A: Statistical Mechanics and its Applications 384 (2007) 2, pp. 725-732

In order to describe the community structure upon the dynamical evolution of complex networks, we propose a new community based evolving network (CBEN) model having increasing communities with preferential mechanisms of both community sizes and node degrees, whose cumulative distribution and raw...
