Peer-to-Peer Network Model with Three-tier Topology Based on Auto Clustering
Chenxi Zhang · 2009
Super nodes of conventional hybrid P2P structure,which is two-tier topology,may overload because they mange both query routing and file management.The oversimplified way of generating a super node may bring mismatch between overlay topology and geography locality,and it also can not display the interests in neighborhoods.A P2P network model with three-tier topology based on auto clustering was proposed.In the model,two functions of super nodes in two-tier topology,file management and query routing,were disposed by two kinds of nodes respectively,and geography localities of nodes were considered.Nodes in P2P networks are able to self-organize based on their characters.Auto clustering was constructed to improve the performance.The experiment implies that the P2P network model with three-tier topology based on auto clustering is able to organize resources effectively and provide efficient search.
