Social-P2P: Social network-based P2P file sharing system

摘要: A peer-to-peer (P2P) file sharing system provides a platform that enables users to share their files. Retrieving files efficiently and trustworthily in such large jumbled is critically important. However, the issues of efficient searching trustworthy have only been studied separately. Simply combining two separate strategies dealing with each issue doubles overhead. In this paper, we first study trace data from Facebook BitTorrent. Guided by observations, propose P2P based on social networks for simultaneous sharing, namely Social-P2P. Social-P2P groups common-multi-interest nodes into cluster further connects socially close within cluster. The comparably stable form DHT inter-cluster searching. query forwarded routing then along constructed connections cluster, which achieves high hit rate reliable routing. Sharing among friends discourages providing faulty since people are unlikely risk reputation real world. Experimental results show leveraging network, highly sharing.
