复杂网络的可导航性

Navigability of Complex Networks

Marian Boguna, Dmitri Krioukov, kc claffy

摘要:

在自然界和人为的复杂系统中,信息通过网络路由是一种普遍现象。当每个节点完全了解全局网络连通性时,找到短通信路径仅仅是分布式计算的问题。然而,在许多真实的网络中,即使没有这种全局智能,节点也能有效地通信。在这里,我们表明,许多复杂网络的特殊结构特征支持有效的通信,而无需全局知识。我们还描述了一个一般的机制,解释网络结构和功能之间的这种联系。这种机制依赖于隐藏在可观察网络背后的度量空间的存在。我们的研究结果表明,自然界中的真实网络具有尚未发现的底层度量空间。他们的发现将具有实际应用,从互联网路由和搜索社交网络,到研究神经,基因调控网络或信号通路中的信息流。

英文摘要:

Routing information through networks is a universal phenomenon in both natural and manmade complex systems. When each node has full knowledge of the global network connectivity, finding short communication paths is merely a matter of distributed computation. However, in many real networks nodes communicate efficiently even without such global intelligence. Here we show that the peculiar structural characteristics of many complex networks support efficient communication without global knowledge. We also describe a general mechanism that explains this connection between network structure and function. This mechanism relies on the presence of a metric space hidden behind an observable network. Our findings suggest that real networks in nature have underlying metric spaces that remain undiscovered. Their discovery would have practical applications ranging from routing in the Internet and searching social networks, to studying information flows in neural, gene regulatory networks, or signaling pathways.
