Peer-to-peer applications (P2P) are no longer limited to home users, and start being accepted in academic and corporate environments. While file sharing and instant messaging applications are the most traditional examples, they are no longer the only ones benefiting from the potential advantages of P2P networks. For example, network file storage, data transmission, distributed computing, and co...

Massively distributed peer-to-peer (P2P) computing systems offer unprecedented levels of computing power. However there is no widely used peer interface and as a result many P2P systems have been developed to support specific services. This paper proposes a P2P middleware architecture that directly supports the formation of service networks based on secure interconnections between peers. The P2...

Distributed computing and Peer-to-Peer (P2P) systems have emerged as an active research field that combines techniques which cover networks, distributed computing, distributed database, and the various distributed applications. Distributed Computing and P2P systems realize information systems that scale to voluminous information on very large numbers of participating nodes. Data mining on large...

recently, peer-to-peer (p2p) networks contribute to a large fraction of the internet backbone traffic. consequently, misusing such networks for malicious purposes is a potential side effect. in this review article, we investigate different techniques of misusing p2p overlay networks to launch large-scale next-generation distributed denial of service (ddos) attacks. in particular, we investigate...

Peer-to-peer (P2P) networks and grids are distributed computing models that enable decentralized collaboration by integrating computers into networks in which each can consume and offer services. P2P is a class of self-organizing systems or applications that takes advantage of distributed resources – storage, processing, information, and human presence – available at the Internet's edges. A gri...

Optimizing and focusing search and results ranking in P2P networks becomes more and more important with the increasing size of these networks. Even though a few approaches have already started to investigate the computation of PageRank-like values in P2P environments, none so far has investigated how personalization could be added to it. This paper tackles the problem of distributedly computing...

Recently, Peer-to-Peer (P2P) technology has become important in designing (desktop) grids for large-scale distributed computing over the Internet. We present a middleware for distributed computing based on Peer-to-Peer systems. When combining public-resource computation ideas with concepts of P2P networks, new challenges occur due to the lack of global knowledge as there is no central administr...

Peer-to-Peer (P2P) systems are emerging as a “new” form of distributed computing with a strong emphasis on selforganization, decentralization and autonomy of the participating nodes. Self-organization, autonomy and decentralization allow for highly adaptive, robust and scalable networks making P2P an increasingly interesting way to design distributed systems. Unfortunately it is still very diff...

Optimistic replication can provide high data availability for collaborative applications in large scale distributed systems (grid, P2P, and mobile systems). However, if data reconciliation is performed by a single node, data availability remains an important issue since the reconciler node can fail. Thus, reconciliation should also be distributed and reconciliation data should be replicated. We...

The goal of distributed learning in P2P networks is to achieve results as close as possible to those from centralized approaches. Learning models of classification in a P2P network faces several challenges like scalability, peer dynamism, asynchronism and data privacy preservation. In this paper, we study the feasibility of building SVM classifiers in a P2P network. We show how cascading SVM ca...
