The Research of Resource Locating Model Based on Sub-Domain Hybrid P2P Network

This paper proposes a sub-domain hybrid P2P network model, and gives a detailed analysis about the design idea of the model. On the one hand, the model makes full use of the advantages of supporting fuzzy queries in the unstructured network. On the other hand, it also maintains efficient in resource locating in structured P2P network. The nodes are gathered into a domain according to approaching of physical location, the nodes in a domain can form a structured P2P network, and interdomain is connected together in the form of unstructured P2P networks. Simulations results show that this model can both improve efficiency in locating resource and promote the recall ratio.
