Abstract Peer-to-peer databases are becoming prevalent on the Internet for distribution and sharing of documents, applications, and other digital media. The problem of answering large scale, ad-hoc analysis queries e.g., aggregation queries on these databases poses unique challenges. Exact solutions can be time consuming and
Aggregate Queries in Peer-to-Peer OLAP Mauricio Minuto Espil Ponticia Universidad Catolica Argentina mminutouca.edu.ar Alejandro A. Vaisman Universidad de Buenos Aires avaismandc.uba.ar ABSTRACT A peer-to-peer (P2P) data management system consists es-sentially of a network of peer systems, each maintaining full autonomy over its own data
Abstract. A peer-to-peer (P2P) data management system consists essentially of a network of peer systems, each maintaining full autonomy over its own data resources. Data exchange between peers occurs when one of them, in the role of a local peer, needs data available in other nodes, denoted the acquaintances of the local peer.
First, we add a query processing layer to perform innetwork data aggregation over peer caches. Second, we introduce the concept of Query-Trails a cache listing recent data requestors.

Abstract. Computing aggregates over distributed data sets constitutes an interesting class of distributed queries. Recent advances in peer-to-peer discovery of data sources and query processing techniques have made such queries feasible and potentially more frequent. The concurrent execution of
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

Apr 14, 2004 Abstract. In this paper, cell abstract indices are presented to process content-based approximate queries in structured P2P data systems. It can be used to search as few peers as possible but get as many returns satisfying users queries as possible on the guarantee of high autonomy of peers.
Second, we propose Digest, a two-tier system for correct and efficient query answering by sampling. At the top tier, we develop a query evaluation engine that uses the samples collected from the peer-to-peer database to continually estimate the running result of the approximate continuous aggregate query with guaranteed precision.

Abstract. The fundamental drawback of unstructured peer-to-peer (P2P) networks is the ooding-based query processing protocol that seriously limits their scalability. As a result, a signicant amount of research work has focused on designing ecient search protocols that reduce the overall communication cost.

With the growing use of location-based services, location privacy attracts increasing attention from users, industry, and the research community. While considerable effort has been devoted to inventing techniques that prevent service providers from knowing a users exact location, relatively little attention has been paid to enabling so-called peer-wise privacy--the protection of a users ...
With the increase of data generation in distributed fashions such as peer-to-peer systems and sensor networks, top-k query processing which returns only a small set of data that satisfies many users preferences, becomes a substantial issue.When data are periodically updated in each epoch e.g., weather information, without any techniques, a naive solution is to aggregate
Then, to improve system scalability of processing continuous privacy-aware queries, we propose a shared execution paradigm that shares query processing among a large number of continuous queries. The proposed scalable paradigm can be tuned through two parameters to trade off between system scalability and answer optimality.
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 A super-peeris a node in a peer-to-peer network that operates both as a server to a set of clients, and as an equal in a network of super-peers. Super-peer networks strike a balance between the inherent efciency of centralized search, and the autonomy, load balancing and robustness to attacks provided by distributed search.
