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 …

Statistical properties of weighted complex networks characterized by metaweights

Furuya, Shuhei; Yakubo, Kousuke - In: Physica A: Statistical Mechanics and its Applications 389 (2010) 6, pp. 1265-1272

We propose several characterizations of weighted complex networks by incorporating the concept of metaweight into the clustering coefficient, degree correlation, and module decomposition. These incorporations make it possible to describe weighted networks depending on how strongly we emphasize...

Detecting overlapping communities in networks using the maximal sub-graph and the clustering coefficient

Cui, Yaozu; Wang, Xingyuan; Li, Junqiu - In: Physica A: Statistical Mechanics and its Applications 405 (2014) C, pp. 85-91

In this paper, we present an alternate algorithm for detecting overlapping community structures in the complex network. Two concepts named the maximal sub-graph and the clustering coefficient between two neighboring communities are introduced. First, all the maximal sub-graphs are extracted from...

Clustering coefficients of growing networks

Shi, Dinghua; Zhu, Stuart X.; Liu, Liming - In: Physica A: Statistical Mechanics and its Applications 381 (2007) C, pp. 515-524

In this paper, we develop a general analytical method to compute clustering coefficients of growing networks. This method can be applied to any network as long as we can construct and solve the dynamic equation for the degree of any node. We also verify the accuracy of the method through simulation.
