People join peer-to-peer networks for economic and social reasons. From an economic perspective, people join peer-to-peer (P2P) networks based on the size of the networks. However, from a sociological perspective, when people adopt technologies, they create an alternative social network motivated by extrinsic and intrinsic rewards. In this study, we develop a conceptual framework for measuring ...

Emerging peer-to-peer applications require efficient group communication. However, current techniques for group communication are not optimal for peer-to-peer networks, which do not have group communication methods themselves. This paper presents the novel multiring topology, which is designed to meet requirements of high performance group communication in peer-to-peer networks. It improves dat...

Nowadays, the security of P2P networks is alarming ascribing to worms which propagate by exploiting common vulnerabilities in P2P software. Taking account of the topology of P2P networks and the behavior of worms, this paper models the propagation of active worms in unstructured P2P networks. Simulations indicate that propagation of worms in P2P networks is much faster than that in un-P2P netwo...

In order to guarantee both the efficiency and robustness in the Peer-to-Peer (P2P) network, the paper designs a novel Super-node Overlay Based on Information Exchange called SOBIE. Differing from current structured and unstructured, or meshed and tree-like P2P overlay, the SOBIE is a whole new structure to improve the efficiency of searching in the P2P network. The main contributions are 1) to ...

Recent years, with the rapid development of P2P networks, the security problem of these networks has become increasingly obvious. According to the behavior of selfishness and betrayal for nodes in P2P networks, this paper analyzes and contrasts the benefits of these nodes, and presents the P2P game model with the penalty factor. The reasonable analysis and simulation by gambit prove that, addit...

In this paper we introduce DANTE, an unstructured P2P system in which the topology of the underlying overlay network can be dynamically adapted to the system conditions. Such an adaption is performed by the peers in an autonomous manner. DANTE uses a simple search mechanism based on random walks that, combined with the topology adaptation, allows it to work in a very efficient way. We have eval...

This paper describes a research work on peer-to-peer music search based on the combination of content based descriptors and textual metadata. The envisaged scenario is the one of a user who searches for documents according either to their melodic and rhythmic content, and to additional information about the title, the instrumentation, or tempo in the form of textual metadata. Two different over...
