Gnutella环境下资源定位方法的改进

本文在已有研究的基础上提出了一种基于节点间部分通路的资源定位方法,加入节点基于邻居节点的逻辑度选择要建立链接的节点,请求节点通过所构建的逻辑结构来定位资源。仿真实验的结果表明,与传统广播方法相比,所提出的方法能有效地降低Gnutella网络的通讯负载,减少冗余消息,提高Gnutella网络的可扩展性,这些对于未来智能网络打印机的研发具有深远意义。

Improvement of Resource Location Mechanism in Gnutella Network

This paper presents a resource location mechanism based on the partial interconnection of peers on the basis of existent study of Gnutella search mechanism.The joining peer chooses peers to establish links according to the logical degree of adjacent peers in current Gnutella network,and the query peer locates resource through the logical structure constructed in the current Gnutella network.The simulation result shows that,compare with the traditional Flooding,our mechanism can efficiently depress the traff...
