动态构造特征可调节的小世界P2P网络*

P2P网络是一个动态网络，静态模型并不适用于构造P2P网络。针对目前的动态模型都存在一定局限性,不能够根据需要调节不同的网络特征，提出一种新的小世界P2P网络的动态构造方法。该方法能够利用构造参数调节网络的平均度数、聚类系数和平均路径长度。仿真实验表明，随网络规模扩大网络持续维持良好的小世界特征，且构造参数能够有效地调节网络的小世界特征。

Dynamic structuring small world P2P networks of character adjustable

In the dynamic model, the numbers of nodes in network increase over time, and network maintain the small-world features. Due to the P2P network is a dynamic network, static model does not apply to P2P network structure, but dynamic model have some limitations that they do not adjust the different network features according to requirement. The paper presented a new dynamic structure method of small-world P2P network, which could use structure parameter to adjust the average degree, cluster coefficient and average path length of network. Simulation results show that, with the network scale expansion the network maintain small-world features, and structural parameters can effectively regulate the small world network features.
