Aggregate Query Processing In Peer To Peer Networks With Synopsis

Evaluated and Suggested Range aggregate query . - CORE

This paper presents 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 and also an adaptive dual-phase approach based on random walks of the P2P graph for efficiently serving range aggregate queries on data cubes in a peer to peer system.

In recent years, the data management community has begun to consider situations in which data access is closely tied to network routing and distributed acquisition: examples include, sensor networks that execute queries about reachable nodes or contiguous regions, declarative networks that maintain information about shortest paths and reachable endpoints, and distributed and peer-to-peer .

Designing a Super-Peer Network

a network of super-peers. Super-peer networks strike a balance between the inherent efficiency of centralized search, and the autonomy, load balancing and robustness to attacks provided by distributed search. Furthermore, they take advantage of the heterogeneity of capabilities (e.g., bandwidth, processing power) across peers, which recent studies

To answer an aggregate query, a large proportion of the databases needs to be accessed. Compared to non-aggregate queries, aggregate queries are expen-sive and require long processing time. While parallel and/or dis-tributed processing techniques can be employed to speed up the processing of such queries, the users may still find the long waiting
