针对实现网络特征的真实情况,提出了一类可调聚类系数的加权无标度网络模型,该模型能够重现现实网络权重和节点度呈幂律分布的统计特性.特别是聚类系数与度之间的非线性关系,恰好符合某些现实网络聚类系数与度之间的平头关系特征.最后研究了可调聚类系数加权网络模型中的拥塞问题.采用基于强度优先传递的局部路由策略,分析了网络中的流量传输问题.
We propose an evolutionary model for weighted network with tunable clustering coefficient according to characteristics of real network. The model gives power-law distributions of degree, weight, and strength, as confirmed in many real network. In particular, the weighted model has a nonlinear correlation between average clustering coefficient and degree, which is in good agreement with fiat head real weighted technological network. Moreove, the effect of the weighted network structure on traffic delivery is studied. The packet traffic flow on the weighted scale-free network is investigated based on the local routing strategy using node strength, and the delivering ability of node is controlled by node strength. The simulations show that the traffic dynamics depends strongly on the controlled parameter.
