基于度的P2P网络拓扑结构

A P2P Net Topology Structure Based on Degree

依据Small World现象和Internet的Power-law分布特征,构建了基于度数确定CenterNode,由CenterNode划定域,进而由CenterNode进行叶子节点管理的拓扑结构.对该结构的模拟实验表明,基于度的拓扑结构在路由查找时间和消息消耗上有明显的优势.

According to the Small World Phenomenon and the Power-law distribution of the Internet,the topology structure is constructed based on the degree of the node to choose some nodes as CenterNode,using it to designate domain,then,to manage the leaf node.The results of the model simulation show that the topology structure based on the degree has obvious advantages in the time seeking and the information consumption.
