Accuracy of Aggregation in Peer
Know More
Abstract Peer-to-peer routing mechanisms are resilient to churn in the overlay network layer A major challenge for peer-to-peer database man-agement systems is to provide similar robustness in the data and query processing layer In this paper we in particular study aggregation queries and present a new approach to increasing accuracy of...
Query Routing and Processing in Peer
Know More
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 queri The focus in such systems is how to carry out an efficient query routing in order to find the nodes storing a desired file...

P2P Peer To Peer File Sharing
Know More
Feb 14 2018 0183 32 When the peer with requested file is found referred to as query hit the query flooding stops and it sends back the file name and file size to the client thus following the reverse path If there are multiple query hits the client selects from one of these peers Gnutella was the first decentralized peer to peer network...

Robust and efficient aggregate query processing in peer
Know More
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...

Global aggregate view selection in a peer warehousing
Know More
Abstract Selecting views to materialize is one of the most important decisions to make when designing a data warehouse In a peer data warehouse design this problem is more difficult than in a centralized data warehouse design since the costs of global communication data transfer and data transformation between peers need to be additionally considered for getting the final integrated...

Efficient Range Query Processing in Peer
Know More
Abstract With the increasing popularity of the peer-to-peer P2P computing paradigm many general range query schemes for distributed hash table DHT -based P2P systems have been proposed Although those schemes can provide range query capability without modifying the underlying DHTs they have the query delay depending on both the scale of the system and the size of the query space or...
