Abstract
Use of peer-to-peer technologies have been prevalent in sharing files and media over internet. This project proposes a new cooperative file sharing and storage system that allows users to store, share and find files over a robust and scalable network. This system is based on peer-to-peer technologies and provides a self-managed, decentralized, efficient, load-balanced and distributed way to store and retrieve files on peer nodes ....etc

Randomized Protocols for Duplicate Elimination in Peer-to-Peer Storage Systems



INTRODUCTION

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, perform ....etc

ABSTRACT


PEER-TO-PEER (P2P) computing systems have been thought of as a powerful paradigm for data sharing, and peerbased data management has attracted increasing interest from the database and information retrieval communities recently. Due to its desirable features like low depl ....etc

Rumor Riding: Anonymizing Unstructured Peer-to-Peer Systems JAVA

ABSTRACT
Although anonymizing Peer-to-Peer (P2P) systems often incurs extra traffic costs, many systems try to mask the
identities of their users for privacy considerations. Existing anonymity approaches are mainly path-based: peers
have to pre-construct an anonymous path before transmission. The overhead of maintaining and updating such
paths is significantly high. We propose Rumor Riding (RR), a lightweight and non-path-based mutual anonymity
protocol for ....etc

Peer-to-Peer Systems



Peer-to-Peer

An alternative to the client/server model of distributed computing is the peer-to-peer model.
Client/server is inherently hierarchical, with resources centralized on a limited number of servers.
In peer-to-peer networks, both resources and control are widely distributed among nodes that are theoretically equals. (A node with more information, better information, or more power may be more equal, but that is a function of the node, not the net ....etc

Spatial Data Query Support in Peer-to-Peer Systems



Motivation

Spatial data sets are used for many applications, e.g., GIS, CAD,
P2P systems provide a distributed platform that is very scalable.
Pros:
Scalability, no central point of failure
Cons:
Very dynamic (unreliable), topology maintenance required

Distributed Hash Tables (DHT)

Abstract In unstructured peer-to-peer networks, the average response latency and traffic cost of a query are two main performance metrics. Controlled-flooding resource query algorithms are widely used in unstructured networks such as peer-to-peer networks. In this paper, we propose a novel algorithm named Selective Dynamic Query (SDQ). Based on mathematical programming, SDQ calculates the optimal combination of an integer TTL value and a set of neighbors to control the scope of the next query. Our results demonstrate that SDQ provides finer gr ....etc

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 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
