可调聚类系数加权无标度网络建模及其拥塞问题研究

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．     

Robust adaptive synchronization of uncertain and delayed dynamical complex networks with faulty network

<正>This paper presents a new robust adaptive synchronization method for a class of uncertain dynamical complex networks with network failures and coupling time-varying delays.Adaptive schemes are proposed to adjust controller parameters for the faulty network compensations,as well as to estimate the upper and lower bounds of delayed state errors and perturbations to compensate the effects of delay and perturbation on-line without assuming symmetry or irreducibility of networks.It is shown that,through Lyapunov stability theory,distributed adaptive controllers constructed by the adaptive schemes are successful in ensuring the achievement of asymptotic synchronization of networks in the present of faulty and delayed networks,and perturbation inputs.A Chua's circuit network example is finally given to show the effectiveness of the proposed synchronization criteria.
