  • Query Routing and Processing in Peer-To-Peer Data Sharing

    Abstract. Sharing musical files via the Internet was the essential motivation of early P2P systems. Despite of the great success of the P2P file sharing systems these systems support only "simple" queries. The focus in such systems is how to carry out an efficient query routing in order to find the nodes storing a desired file.

    ABSTRACT. In this paper we propose a framework called CQ-Buddy for supporting distributed continuous query (CQ) processing system based on Peer-to-Peer (P2P) technology. Working on the basis of peer heterogeneity peers in a CQ-Buddy network "help" one another by sharing query workload and providing data.

  • Robust and efficient aggregate query processing in peer-to

    The ability to approximately answer aggregation queries accurately and efficiently is of great benefit for decision support and data mining tools. A P2P network consists of numerous peer nodes that share data and resources with other peers on an equal basis. Unlike traditional client-server models no central coordination exists in a P2P system thus there is no central point of failure.
