Efficient Approximate Query Processing in Peer-to-Peer Networks


Abstract”Peer-to-peer (P2P) 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, for example, aggregation queries, on these databases poses unique challenges. Exact solutions can be time consuming and difficult to implement, given the distributed and dynamic nature of P2P databases. In this paper, we present novel sampling-based tech ....etc

EVOLUTION OF PEER TO PEER DOWNLOADING
PEER TO PEER NETWORK
What is a peer to peer network?
A peer to peer network is a network that relies on the computing power & bandwidth of the participants on the network.
P2p networks are typically used for connecting nodes via largely ad_hoc connections.
Such networks are useful for sharing content files containing audio,video ,data & anything in digital format.

Peer-to-Peer (P2P) is not a new concept but it is not just limited to file distributed resources to perform a critical function in a decentralized manner. P2P aims at avoiding the dependency on centralized points, providing direct communication between peers, enabling resource aggregation and exchange of services. With the growth of unstructured P2P networks like Napster, Gnutella etc., large scale distributed applications such as distributed data storage and cooperative backup are gaining interest ....etc

Randomized Protocol for Duplicate Elimination in Peer-to-Peer Storage System


PEER-TO-PEER systems have emerged as cost-effective alternatives for scalable data sharing, backup, and archival storage. Peers contribute data and storage and, in return, gain access to data at other peers. Effective storage management is an important issue in the deployment of such systems. Data replication and caching are key enabling techniques for scalability, performance, and availability. In this context, an important problem relates to ....etc

Abstract”
The peer-to-peer (P2P) file-sharing applications are becoming increasingly popular and account for more than 70% of the Internetâ„¢s bandwidth usage. Measurement studies show that a typical download of a file can take from minutes up to several hours depending on the level of network congestion or the service capacity fluctuation. In this paper, we consider two major factors that have significant impact on average download time, namely, the spatial heterogeneity of service capacities in different source pe ....etc

Introduction
Human nature is defined by an incessant urge to improve. This drive has brought us from the wheel to the jetliners, caves to skyscrapers, and the abacus to computers. And with each milestone in technology, man adapts himself to be more suited for work with the novelty. The story has not been much different in the area of computers. In fact, when it comes to computers, this adaptability of man becomes far too prominent and pronounced. Computers have come to change every walk of our lives, be it banking, purchases, communication, e ....etc

Peer-to-peer computing consists of an open-ended network of distributed computational peers, where each peer shares data and services with a set of other peers, called its acquaintances. The peer-to-peer paradigm was initially popularized by file-sharing systems such as Napster and Gnutella, but its basic ideas and principles have now found their way into more critical and complex data-sharing applications like those for electronic medical records and scientific data. In such environments, data sharing poses new challenges mainly due to the lac ....etc

MINING FILE DOWNLOADING TIME IN STOCHASTIC PEER TO PEER NETWORKS
Abstract: On-demand routing protocols use route caches to make routing decisions. Due to mobility, cached routes easily become stale. To address the cache staleness issue, prior work in DSR used heuristics with ad hoc parameters to predict the lifetime of a page link or a route. However, heuristics cannot accurately estimate timeouts because topology changes are unpredictable. In this paper, we propose proactively disseminating the broken page link information to the nodes that h ....etc
