摘要:

多组群网络应用是目前比较流行的互联网服务模式之一,本文主要针对多组群网络应用的节点分组及评价方法进行研究探讨,设计了一种基于无监督聚类方法和贝叶斯分类器的高质量分组算法Clustyes,提出了基于“组耦合度”的可调多取向分组评价模型,该模型较好地将组内节点间往返时延、分组丢失率和跳数3个指标对组内通信的影响有机地量化融合。Clustyes算法在NS-3上进行了模拟,结果表明,使用该算法获得的分组具有组内节点通信性能好、稳定性高、物理距离近的优点。

Abstract:

The multi-group network application is one of the popular network service models,internet hosts grouping method and the evaluation mode1 were focused on. A new internet hosts grouping algorithm ca11ed Clustyes was presented. Also,based on the concept of group coupling degree,an evaluation mode1 of hosts grouping performance was constructed. RTT,hops,and packet 1oss rate in network communication were considered in this evaluation mode1. The experiment was simulated on the NS-3,and the results show that the new grouping algorithm Clustyes can generate groups,in which the hosts can communicate quickly,stably,and closely in physica1 distance.

Key words: grouping evaluation mode1, group coupling degree, cluster analysis, Bayesian classifier
