A Peer-to-Peer (P2P) Grid would comprise services that include those of Grids and P2P networks and naturally support environments that have features of both limiting cases. Such a P2P grid integrates the evolving ideas of computational grids, distributed objects, web services, P2P networks and message oriented middleware. In this paper we investigate the architecture, comprising a distributed b...

1 Introduction Today, peer-to-peer technology has reached the peak of its popularity. Currently, P2P file sharing represents the dominant usage component of Internet bandwidth. Moreover, P2P networks enable sharing of other different computer resources and services, including distributed (collaborative) computing, processing cycles, instant messaging, CPU and storage resources, etc. Peer-to-pee...

Peer-to-peer (P2P) computing is currently receiving a great deal of attention. Much of the current attention is focused on the use of P2P computing for exchanging media files. But P2P systems have actually been around for a long time and many application scenarios exist. In this paper we discuss on one hand the evolution of P2P middleware from simple file-sharing to decentralized data storage; ...

This paper presents a distributed search engine based on semantic P2P Networks. The user’s computers join the domains in which user wants to share information in semantic P2P networks which is domain specific virtual tree (VIRGO ). Each user computer contains search engine which indexes the domain specific information on local computer or Internet. We can get all search information through P2P ...

We present an efficient and robust network topology for managing distributed resources in P2P-Grid environments. This topology is called TreeP and exploits both features of P2P and grid computing models. It uses P2P properties in looking for available resources, while using Grid properties to implement communications and computations on a distributed computing platform. Here, we present how thi...

The problem of automated semantic peer-to-peer (P2P) service composition has been addressed in cross-disciplinary research of semantic web and P2P computing. Solutions for semantic web service composition in structured P2P networks benefit from the underlying distributed global index but at the cost of network traffic overhead for its maintenance. Current solutions to service composition in uns...

This paper proposes an efficient algorithm for clustering nodes, classifying and replication of content on demand basis for content distribution in p2p overlay networks. Peer-to-peer overlay networks are a good solution for distributed computing than client-server model since nodes in P2P networks act both as client and server. With such functionality of managing replicas is an astonishing task...

This thesis discusses the implementation of function optimization algorithms through distributed and decentralized processing in a peer-to-peer fashion. Our research is focused on a fully decentralized, general purpose P2P environment, with no special or ad-hoc facility for executing optimization tasks. Relevant information is exchanged among nodes by means of epidemic protocols, exploiting the...

Peer-to-Peer (P2P) computing, a novel paradigm for distributed information technology, is currently receiving ever increasing interest of both academia and industry. Recent efforts intended to integrate multi-agent and P2P architectures is one of such very promising new opportunities. Indeed, multiagent system (MAS) may be thought of as a multitude of autonomous entities, and, therefore, struct...
