A peer-to-peer (p2p) system provides the networking substrate for the execution of distributed applications. It is made of peers that interact over an overlay network. Overlay networks are highly dynamic, as peers can join and leave at any time. Traditional process calculi, such as π-calculus, CCS and others, seem inadequate to capture these kinds of networks, their routing mechanisms, and to v...

Imagine you are overweight and you spot your favorite pastry in the storefront of a bakery. How do you manage to resist this temptation? Or to give other examples, how do you manage to restrain yourself from overspending or succumbing to sexual temptations? The present article summarizes two recent studies stressing the fundamental importance of inhibition in the process of decision making. Bas...

Peer-to-peer systems were getting popular in the past by applications that have built over them, e.g. file sharing programs. They also are interesting in the actual research because of they could be widely used to build lots of network applications. This paper focus on two protocols used to build peer-to-peer systems and evaluates their performance: Pastry and Chord. They are classified as a se...

Recently context-based systems become more and more popular as sensor technology is improved and network access is almost omnipresent. Until now, establishing such systems involves larger investments in an appropriate infrastructure. In this paper we propose an architecture for a context-based system based on an overlay network using peer-to-peer technology. Furthermore, we modified the underly...

Because of the increasing interest in mobile ad hoc networks (MANETs) and their inherent similarities to peer-to-peer networks a large number of routing protocols based on peer-to-peer networks have recently been presented to provide distributed network applications with e cient and indirect routing for MANETs. Thomas Zahn and Jochen Schiller suggested MADPastry, an integration of a DHT substra...

This report describes the process of developing and evaluating a component based overlay with the intention of creating a configurable, reusable and extensible implementation. This is done through the use of a new fine grained component architecture accompanied by a surrounding framework to support the interconnection of these components. Through the use of this framework it is then possible to...

This paper discusses the simulation possibilities of unstructured P2P semantic among PeerSim, which is one of the most popular envoironment recently, thanks to its modularity and ease of configuration. This is useful tool to evaluate theoretical model of our project ”Semantic P2P Search engine”: a heterogeneous network of independent nodes with clusters with text documents. Despite the fact tha...
