Data Replication in P2P Systems
In a peer-to-peer (p2p) system, a large number of nodes share data with each other. The participation of nodes is highly dynamic; nodes may enter and leave the system at will. Since, it is not possible to maintain links with all nodes, for performance as well as for privacy and anonymity reasons, each node maintains links with a selected subset of other nodes, thus forming an overlay network. A...
متن کاملData Sharing in P2P Systems
In this chapter, we survey P2P data sharing systems. All along, we focus on the evolution from simple file-sharing systems, with limited functionalities, to Peer Data Management Systems (PDMS) that support advanced applications with more sophisticated data management techniques. Advanced P2P applications are dealing with semantically rich data (e.g. XML documents, relational tables), using a hi...
متن کاملSupporting Data Privacy in P2P Systems
Peer-to-Peer (P2P) systems have been very successful for large-scale data sharing. However, sharing sensitive data, like in online social networks, without appropriate access control, can have undesirable impact on data privacy. Data can be accessed by everyone (by potentially untrusted peers) and used for everything (e.g., for marketing or activities against the owner’s preferences or ethics)....
متن کاملSemantic Data Integration in P2P Systems
In this paper, we study the problem of data integration in P2P systems. Differently from the traditional setting, data integration in these systems is not based on the existence of a global view. Instead, each peer exports data in terms of its own schema, and information integration is achieved by establishing mappings among the various peer schemas. We present a framework that captures this ge...
متن کاملData Sharing in DHT Based P2P Systems
The evolution of peer-to-peer (P2P) systems triggered the building of large scale distributed applications. The main application domain is data sharing across a very large number of highly autonomous participants. Building such data sharing systems is particularly challenging because of the “extreme” characteristics of P2P infrastructures: massive distribution, high churn rate, no global contro...
