具有社会网络特性的P2P分层搜索机制
P2P Hierarchical Searching Mechanism with Social Network Feature
摘要
Abstract
The search mechanism based on flooding in unstructured Peer-to-Peer(P2P) network increases the load of system and structured P2P network requires greater spending to maintain its topologieal structure. This paper proposes a hierarchical searching scheme with social network features in P2P network. It adopts the rationale of social network, high semantic similarity nodes are distributed in the same virtual community, and searching links are actively built between nodes in the same virtual community. Experimental results show that this searching scheme is capable of effectively improving the search efficiency of P2P network.关键词
