Abstract:

In consideration of the limitation of super-peer overlay network, the semantic information was introduced into the super-peers’ organization. A novel P2P(peer-to-peer)searching model, SSP2P, was put forward.The peers in the model were organized in a natural area autonomy system(AAS)based on the small-world theory. A super-peer was selected in each AAS based on power law;and all the super-peers formed different super-peer semantic networks. Thus, a hierarchical super-peer overlay network was formed.The results show that the model reduces the communication cost and enhances the search efficiency while ensuring the system expansibility.It proves that the introduction of semantic information in the construction of a super-peer overlay is favorable to P2P system capability.
