简单快速的分布介数中心度计算

Simple and Fast Distributed Computation of Betweenness Centrality

Pierluigi Crescenzi, Pierre Fraigniaud, Ami Paz

摘要:

介数中心性是一个已成功应用于网络分析的图形参数。在计算机网络的背景下,它被认为是各种目标,从路由到服务布局。然而,正如Maccari等人[INFOCOM 2018]所观察到的那样,由于缺乏用于计算此参数的可用的完全分布式算法,因此对改进协议的介数中心性的研究受到阻碍。我们解决了这个问题,设计一个有效的算法计算介数中心,它可以实现最小的修改任何距离矢量路由协议的基础上贝尔曼福特。我们的实现的收敛时间被证明是成比例的网络的直径

英文摘要:

Betweenness centrality is a graph parameter that has been successfully applied to network analysis. In the context of computer networks, it was considered for various objectives, ranging from routing to service placement. However, as observed by Maccari et al. [INFOCOM 2018], research on betweenness centrality for improving protocols was hampered by the lack of a usable, fully distributed algorithm for computing this parameter. We resolve this issue by designing an efficient algorithm for computing betweenness centrality, which can be implemented by minimal modifications to any distance-vector routing protocol based on Bellman-Ford. The convergence time of our implementation is shown to be proportional to the diameter of the network
