In one of the latest developments in Grid Computing Peer-to-Peer (P2P) networks have become fashionable for the Grid system architecture. The current implementations are either Data Grids or CPU sharing Grids. In this paper we begin to investigate how a P2P network can behave as CPU sharing Grid. In our model the nodes of the network are very simple and either require or offer service for the e...

To provide the stable and continuous network services in cases of large-scale natural disasters, computers must use extremely limited network and computational resources effectively without imposing additional administrative burdens. The authors propose a P2P Information Sharing System for affected areas based on our proposed structured P2P network called the Well-distribution Algorithm for an ...

We consider the problem of collaborative search across a large number of digital libraries and query routing strategies in a peerto-peer (P2P) environment. Both digital libraries and users are equally viewed as peers and, thus, as part of the P2P network. Our system provides a versatile platform for a scalable search engine combining local index structures of autonomous peers with a global dire...

Global stabilization of energy networks without centralised control is a challenge. This paper explores the potential of coordination of energy usage of intelligent thermostatically controlled appliances (TCA) using a p2p network. A p2p tree overlay provides the basic structure for distributed plan aggregation and distribution. The approach is presented and discussed in the light of the risks a...

Peer-to-Peer (P2P) networks are spreading to Mobile Networks. Mobile Ad hoc Networks (MANET) and P2P have already been under thorough research focus but lately also cellular networks and P2P have drawn more interest. This paper suggests a hybrid, mobile overlay P2P architecture, that connects MANET and cellular P2P networks via Mobile Proxies to universal P2P networks, called a Mobile Peer-to-P...

Botnets, in particular the Storm botnet, have been garnering much attention as vehicles for Internet crime. Storm uses a modified version of Overnet, a structured peer-to-peer (P2P) overlay network protocol, to build its command and control (C&C) infrastructure. In this study, we use simulation to determine whether there are any significant advantages or disadvantages to employing structured P2...

Due to its ability to deliver scalable and fault-tolerant solutions, applications based on the peer-to-peer (P2P) paradigm are used by millions of users on the internet. Recently, wireless mesh networks (WMNs) have attracted a lot of interest from both academia and industry, because of their potential to provide flexible and alternative broadband wireless internet connectivity. However, due to ...

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 applications. This paper is devoted for this issue by comparing some typcial P2P systems widely used in digtal libr...

Distributed hash tables (DHTs), used in a number of structured peer-to-peer (P2P) systems provide efficient mechanisms for resource placement and location. A key distinguishing feature of current DHT systems, such as Chord, Pastry, CAN and Tapestry, is the way they handle locality in the underlying network. Topology-based node identifier assignment, proximity routing, and proximity neighbor sel...

by William F. Acosta Peer-to-peer (P2P) networks are decentralized, distributed networks where the participating nodes self-organize and communicate with each other to support a distributed application. P2P networks have been used to support such diverse applications as file sharing, distributed storage and backup, and content distribution. Because P2P networks are decentralized, the manner in ...
