Effective co-betweenness centrality computation [PDF]
Proceedings of the 7th ACM international conference on Web search and data mining, 2014 Betweenness centrality of vertices is essential in the analysis of social and information networks, and co-betweenness centrality is one of two natural ways to extend it to sets of vertices. Existing algorithms for co-betweenness centrality computation suffer from at least one of the following problems: i) their applicability is limited to special ...

Multiplex Networks of the Guarantee Market: Evidence from China
Complexity, 2017 We investigate a multiplex network of the guarantee market with three layers corresponding to different types of guarantee relationships in China. We find that three single-layer networks all have the scale-free property and are of disassortative nature.

Energy-Aware Routing in Wireless Sensor Networks Using Local Betweenness Centrality
International Journal of Distributed Sensor Networks, 2013 We propose an energy-aware dynamic routing strategy in order to provide balanced energy consumption in wireless sensor networks, hence, prolonging the lifetime of the network.

Temporal betweenness centrality on shortest walks variants
Applied Network ScienceBetweenness centrality has been extensively studied since its introduction in 1977 as a measure of node importance in graphs. This measure has found use in various applications and has been extended to temporal graphs with time-labeled edges.

Reconstruction of Networks from Their Betweenness Centrality [PDF]
, 2008 In this paper we study the reconstruction of a network topology from the values of its betweenness centrality, a measure of the influence of each of its nodes in the dissemination of information over the network. We consider a simple metaheuristic, simulated annealing, as the combinatorial optimization method to generate the network from the values of ...
