Study on Base-Core Mode Coupling Networks
Authors: , ,
Abstract: There exist a kind of networks composed of two coupled network which are a base network and a core network respectively. For instance, an urban public transport network consists of a bus network (base network) and subway network (core network), the two networks are coupled together. We proposed a base-core coupling network model to study the performance of the kind of coupling network. In the model, the base network is generated first, then the nodes of the core network are selected from the base network according to a preferential selection scheme based on and , where and represent the node degree and betweenness respectively, represents the preferential selection exponent. Under different value of , we investigate the performance of the coupling network in different network structure and different network size collocations. Simulation result shows: the greater value of , the higher of the use rate of the core network and the smaller of the weighted average shortest path length of the coupling network. Namely, a higher preferential selection exponent corresponds to better coupling network performance.
