Self-organizing structure and availability of almost unlimited resource capacities make the peer-to-peer architecture very attractive for large-scale sharing of annotated data in Web 2.0 scenarios. This paper addresses the problem of information aggregation and utilization in a decentralized

directly to their customers. Hence, it is desirable for ISPs to economize existing infrastructure to support a variety of applications and services. We propose a dynamic mesh-based overlay peer-to-peer infrastructure (D-MORE) and illustrate its example usage case among other potentials. We describe several

Abstract. Existing e-marketplaces, built on traditional client-server architectures, severely restrict the scope and dynamics of Business-to-Business (B2B) interactions. Peer-to-peer (P2P) architectures will provide far more decentralised infrastructures, while allowing a much wider range

Abstract. Peer-to-Peer (P2P) overlay network aims to be a feasible platform for building federated but autonomous digital libraries. However, due to a plethora number of P2P infrastructures and corresponding functionalities, it is often not easy to choose appropriate candidates for specific

that authenticated users have access to resources based on their assigned roles. RBAC is more challenging in peer-to-peer (P2P) systems, due to the lack of centralized administration. In this paper we discuss RBAC over a P2P network and we present an RBAC implementation in the JXTA P2P framework. JXTA is a popular

, especially for grid environment. We believe that peer-to-peer overlay networks are a valuable basis to support some of the main issues of autonomic computing in the particular case of grids. This article presents the construction of an autonomous, decentralized, scalable, and efficient grid monitoring system

. Services are published and deployed with associated metadata de-scribing the service type. This same metadata may be used subsequently by interested parties to discover ser-vices. The infrastructure uses peer-to-peer (P2P) overlay technologies to abstract over the underlying network to deploy and locate

Abstract. We present a contribution on dynamic load balancing for distributed and parallel object-oriented applications. We specially target on peer to peer computing and its capability to distribute parallel computation, which transfer large amount of data (called intensive

This paper presents a decentralized infrastructure, called Web2Peer1, which makes Web pages available on Internet through P2P networks. Different from the conventional Web, the proposed approach does not need, for instance, a HTTP address or a central Web Server. Web2Peer provides a set
