Coalition Formation in P2P File Sharing Systems
P2P file sharing systems are distributed systems consisting of interconnected nodes able to self-organize in networks, with the purpose of sharing content. Recent empirical studies have shown that they suffer from freeloaders, that is, peers that consume many more resources or content than they contribute. In this paper we propose a coalition formation based incentive mechanism for P2P file sha...
متن کاملFile Correspondences Dictionary Construction in Multilingual P2P File Sharing Systems
Sharing files discovery is a fundamental problem in P2P networking. This paper presents a name-based approach for identifying sharing file correspondences in multilingual P2P systems. The problem is first analyzed through comparing the names of the sharing files in different nodes of a real P2P community, which name those files in different languages. Then based on the relationships of those fi...
متن کاملAutomatic Tuning of File Descriptors in P2P File-Sharing Systems
Peer-to-peer file-sharing systems have poor search performance for rare or poorly described files. These files lack a quality or variety of metadata making them hard to match with queries. A server can alleviate this problem by gathering the descriptors used by peers via what we call probe queries, and use these descriptors to improve its own. We consider probe query triggering mechanisms and c...
متن کاملA resources monitoring architecture for P2P file-sharing systems
Resources monitoring is an important problem of the overall efficient usage and control of P2P file-sharing systems. The resources of file-sharing systems can include all distributing servers, programs and peers. Several researches have tried to address this issue, but most of them illuminated P2P traffic characterization, identification and user behavior. Based on previous work, we present a r...
متن کاملFighting Freeloaders in Decentralized P2P File Sharing Systems
Currently used P2P file-sharing systems such as Gnutella suffer from a freeloading problem due to absence of enforcible decentralized mechanism to motivate peers to provide services to others. Freeloading leads to a de facto centralized system that is susceptible to DoS attacks and provides poor service to its participants. In this paper, we propose a decentralized mechanism that avoids on-line...
