摘要
使用K-means的聚类方法,从用户上下线规律的角度,对P2P网络中的用户进行了聚类分析,发现系统中存在稳定的节点类,以及在线规律呈现日周期规律但是与其他类节点可以互补的节点类,我们提出,合理有效地利用这些用户节点可以提高一些P2P系统的性能以及可靠性。
We use the K - means clustering algorithm to categorize users in P2P network from users＇ online and offline discipline point of view. We find that there exists stable node cluster, as well as day - period node cluster which are complementary to other clusters. We propose that rational and effective use of these user nodes can improve performance and reliability of some P2P systems.
