利用介数中心性增强加权动态网络的同步性

Enhancing synchronizability of weighted dynamical networks using betweenness centrality

Mahdi Jalili, Ali Ajdari Rad, Martin Hasler

摘要:

通过将连接图的拉普拉斯算子的特征值比作为同步性测度,提出了一种加权动态网络的方法,以提高动态网络的同步性。该方法是基于节点和边缘介数中心性措施,并在人工构造的无标度,Watts-Strogatz和随机网络以及一些现实世界的图上进行了测试。数值结果还表明,同样的程序可以用来提高网络的相位同步的不同的振荡器。

英文摘要:

By considering the eigenratio of the Laplacian of the connection graph as synchronizability measure, we propose a procedure for weighting dynamical networks to enhance theirsynchronizability. The method is based on node and edge betweenness centrality measures and is tested on artificially const ructed scale-free, Watts-Strogatz and random networks as well as on some real-world graphs. It is also numerically shown that the same procedure could be used to enhance the phase synchronizability of networks of nonidentical oscillators.
