空间增长的发展时间窗口产生多簇小世界网络
Developmental time windows for spatial growth generate multiple-cluster small-world networks
摘要:
许多网络在空间上延伸,可以是度量的(例如地理的)或非度量的(序数的)。空间网络增长依赖于节点之间的距离,可以产生从小世界到线性无标度网络的各种拓扑结构。然而,网络往往缺乏多个集群或社区。但是,如果在开发过程中有时间窗口,则可以生成多个集群。时间窗口确保网络的区域在不同的时间点建立联系。这种新方法可以生成小世界网络,但不是无标度网络。由此产生的拓扑结构严重依赖于时间窗口的重叠以及先锋节点的位置。
英文摘要:
Many networks extent in space, may it be metric (e.g. geographic) or non-metric (ordinal). Spatial network growth, which depends on the distance between nodes, can generate a wide range of topologies from small-world to linear scale-free networks. However, networks often lacked multiple clusters or communities. Multiple clusters can be generated, however, if there are time windows during development. Time windows ensure that regions of the network develop connections at different points in time. This novel approach could generate small-world but not scale-free networks. The resulting topology depended critically on the overlap of time windows as well as on the position of pioneer nodes.
