An Empirical Study of Collusion Behavior in the (2009)
Maze Pp, File-sharing System, Qiao Lian, Zheng Zhang, Ben Y. Zhao, Yafei Dai, ...
Abstract — Peer-to-peer networks often use incentive policies to encourage cooperation between nodes. Such systems are generally susceptible to collusion by groups of users in order to gain unfair...
Towards a More Accurate Availability Evaluation in Peer-to-Peer Storage Systems * (2008)
Zhi Yang, Jing Tian, Yafei Dai
Data availability evaluation is the crucial problem to build large-scale, high available peer-to-peer storage systems by governing many unreliable hosts. However, many recent studies equate host...
P2P file sharing systems often use incentive policies to encourage sharing. With the decrease of free riders, the amount of cheating behaviors has increased. Some users rename a common file with a...

An Interest-based P2P RDF Query Architecture 1 (2008)
Qian Gao, Zhihuan Qiu, Yu Wu, Jing Tian, Yafei Dai
Abstract. Currently most centralized RDF storage and query architectures have problems in query performance and scalability. In this paper we present a distributed RDF query architecture to address...
Abstract: Peer-to-Peer (P2P) has been one of the most important architectures for Internet applications for its inherent scalability, fault tolerance and high performance. The research of P2P storage...
SemanticPeer: An Ontology-Based P2P Lookup Service * (2008)
Jing Tian, Yafei Dai, Xiaoming Li
Abstract. Locating content efficiently and conveniently is the key issue in P2P systems. In this paper we present SemanticPeer, an Ontology-Based P2P lookup service, to address this problem, which is...
Leveraging Duplicates to Improve File Availability of P2P Storage Systems ⋆ (2008)
Min Qu, Yafei Dai, Mingzhong Xiao
Abstract. This paper proposes a strategy of improving file availability of peer-to-peer file storage systems, which provides the ability of identifying duplicate files and leveraging the duplicates....
A Measurement Study of the Structured Overlay Network in P2P File-Sharing Systems (2007)
Mo Zhou, Yafei Dai, Xiaoming Li
The architecture of P2P file-sharing applications has been developing to meet the needs of large scale demands. The structured overlay network, also known as DHT, has been used in these applications...
An empirical study of collusion behavior in the Maze p2p file-sharing system (2007)
Qiao Lian, Zheng Zhang, Mao Yang, Ben Y. Zhao, Yafei Dai, Xiaoming Li
Peer-to-peer networks often use incentive policies to encourage cooperation between nodes. Such systems are generally susceptible to collusion by groups of users in order to gain unfair advantages...

Robust Incentives via Multi-level Tit-for-tat (2006)
Qiao Lian Yu, Yu Peng, Mao Yang, Zheng Zhang, Yafei Dai, Xiaoming Li
Much work has been done to address the need for incentive models in real deployed peer-to-peer networks. In this paper, we discuss problems found with the incentive model in a large, deployed...
SEC: A Practical Secure Erasure Coding Scheme for Peer-to-Peer Storage System (2006)
Jing Tian, Zhi Yang, Yafei Dai
Abstract. Though conventional block cipher is widely used in Peer-to-Peer storage systems, it is insufficient to ensure the confidentiality of long-term archive data because of the inherent...
Deployment of a Large-scale Peer-to-Peer Social Network (2004)
