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.

SCALLOP:A SCALABLE AND LOAD-BALANCED PEER-TO-PEER LOOKUP PROTOCOL

MOTIVATIONS AND PURPOSE

Many large-scaled servers are implemented in a peer-to-peer distributed system due to:
Low cost of workstations
Availability of high speed network
Performance of the system is high due to:
Rapid response time
Less memory space

LOOKUP PROTOCOL

Response time=Lookup time +Service time
Shorter lookup forwarding path ....etc

Additional Director, Directorate of Technical Education, Chennai, India
Research Scholar, Government College of Technology, Coimbatore, India


ABSTRACT
Smart spaces are composed of smart and dummy nodes
which act as the source for providing service. A large
number of cluster groups are formed in the smart space.
Some of these smart spaces are mobile, some are Adhoc
and others are sensor ....etc

Peer-to-Peer File Sharing Across Private Networks Using Proxy Servers


The Internet today is commonly used as a medium to share large size multimedia content. This sharing is carried out, a number of times, through the Peer to Peer sharing architecture rather than the conventional server-client model. The paucity of network addresses in the Internet has led to the emergence of private and global networks. Because the identity of peers in a private network remains hidden behind their global endpoint, P2P applications cannot run betwee ....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.

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)


DHT systems: Content Addressable Network (CAN), Chord, Pastry, etc.
Using DHT to allocate large da ....etc

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

DYNAMIC SEARCH ALGORITHM IN UNSTRUCTURED PEER-TO-PEER NETWORKS--PARALLEL AND DISTRIBUTED SYSTEMS

Designing efficient search algorithms is a key challenge in unstructured peer-to-peer networks. Flooding and random walk (RW) are two typical search algorithms. Flooding searches aggressively and covers the most nodes. However, it generates a large amount of query messages and, thus, does not scale. On the contrary, RW searches conservatively. It only generates a fixed amount of query messages at each hop but would take longer search time. We pr ....etc
