A Database Query Processing Model in Peer-To-Peer Network

database query processing scheme is proposed to limit the search space of the given query by a domain based query routing mechanism which limits the search to related peers. A database query processing model in peer-to-peer networks was designed using top-k query processing technique and implemented using Java, and MySql.

A Novel Efficient Approximate Query Processing In P2P

a) In pure peer-to-peer network peers act as equals, merging the roles of clients and server. In such networks, there is no central server managing the network, neither is there a central router. Some examples of pure P2P Application Layer networks designed for peer-to-peer file sharing are gnutella (pre v0.4) and Freenet.

Query Routing and Distributed Top-k Query Processing in ...

Query processing is the next step after the query routing task. Specifically, after the query is routed to a set of appropriate peers, query processing undertakes the task of combining the results from each peer and returning the final ones to the peer that submitted the original query. In this work, we focus on query processing for top-k queries.

Peer to Peer Networks - an overview ScienceDirect Topics

The most basic network is a stand-alone peer-to-peer network. Peer-to-peer networks are created by connecting each device together through a hub or switch. Each computer, codec, or access control panel is equal in the eyes of the switch. This is adequate for very small networks (Fig. 18.11).
