| 摘 要： | 对基于社区结构的P2P流媒体系统进行了建模研究,总结提出了k-n模型和k-n-t模型两种社区结构模型,并对这两种模型的小世界网络特征作了理论分析和比较。结果表明,k-n模型社区结构比k-n-t模型具有较高的聚集系数,而k-n-t模型社区结构在聚集系数和平均路长两方面取得了更好的折衷。

| Abstract: | A modeling study of community structure based on P2P streaming systems was studied.Two types of community structure models,named k-n model and k-n-t model,were presented,of which the small world network characteristics are theoretically analyzed and compared.Numerical result shows that the community structure of k-n model has a higher clustering coefficient than that of k-n-t model,while the community structure k-n-t model achieves a better tradeoff between clustering coefficient and average path length. |
