| 摘 要： | 在Gnutella网络中如何进行资源定位是提高网络效率、增强网络可扩展性的重要问题.在已有研究的基础上提出一种基于节点逻辑度的资源定位方法,加入节点基于当前Gnutella网络中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.仿真实验结果表明该方法能有效地降低Gnutella网络的通信负载,减少冗余消息,提高Gnutella网络的可扩展性.

| Abstract: | How to locate resources is an important issue to improve network performance and enhance network scalability in Gnutella network.This paper presents a resource location mechanism based on logical degree of peers on the basis of existent study of Gnutella search mechanism.The joining peer chooses peers to establish the links with according to the logical degree of peers in current Gnutella network,and the query peer locates resource through the logical structure constructed in Gnutella network.The simulation... |
