Abstract (sommario):
Lo scopo principale di questa tesi è quello di implementare la rete di anonimizzazione Invisible Internet Project (I2P) all'interno di un prototipo esistente basato su un'architettura cloud peer-to-peer (P2P). Tale prototipo implementa al proprio interno la rete di anonimizzazione The Onion Router (Tor) e il secondo obiettivo di questa tesi è quello di analizzare e valutare le performance offerte da queste due tipologie di reti. Il prototipo, basandosi su un sistema decentralizzato P2P che, rispetto a quello centralizzato non ha il problema di rappresentare un single point of failure, permette

Abstract (sommario):
As the Internet develops and technology evolves, multimedia traffic dominates the Internet. Traditional client-server based video streaming solutions are expensive and suffering from the scalability issue. Inspired by the immense success and efficiency of BitTorrent in distributing file contents to large groups of users, the peer-to-peer (P2P) paradigm has been adopted to provide streaming services including both P2P video-on-demand (VoD) and P2P live streaming. Among the design challenges, one open yet fundamental question is, how to identify the most suitable neighbor for a peer to make a

Decentralized full-text search is still an unsolved problem in peer-to-peer research. As part of this thesis, we introduce Sweep, a fully decentralized full-text search engine built on Apache Lucene, that takes significant steps towards providing reliable, low-latency, and accurate search results. Our main contributions include a novel gossip-based protocol for fast and efficient replication of the search index and a protocol for the automated sharding of the search index. Therefore, each peer maintains a replica of a bounded-size subset of the whole search index also known as shard. Our appro

Abstract (sommario):
The popularity of peer-to-peer networks has grown tremendously in recent times as a result of the ever-improving capabilities of host entities at the edge and the ubiquitous reach of the Internet. The growth has fueled the realization of many peer-to-peer networks in both academia and the commercial arena. Peer-to-peer networks generally fall into one of these categories ??? centralized systems with server-like entities in the network; unstructured systems with random topology and message routing, and structured systems with deterministic topology and routing behavior.

<p>In the environment of the 3:rd generation Internet based on peer-to-peer architecture, well-trusted methods must exist to establish a secure environment. One main issue is the possibility to verify that a node actually is who it claims to be (authentication). Establishment of authentication between nodes in a peer-to-peer environment where nodes are exchanging information directly with each other requires more planning than in a typical client-server environment where the authentication methods are server-based.

Grid computing systems are suffering from reliability and scalability problems caused by their reliance on centralised middleware. In this thesis, we argue that peer to peer middleware could help alleviate these problems. We show that peer to peer techniques can be used to provide reliable storage systems, which can be used as the basis for peer to peer grid middleware. We examine and develop new methods of providing reliable peer to peer storage, giving a new algorithm for this purpose, and assessing its performance through a combination of analysis and simulation.

Peer-to-peer applications enable a group of users to create a communications framework from scratch without the need of a central service provider. This is achievable via the aggregation of resources each one of them provide, creating a completely distributed collaborative environment based in a flat hierarchy of users, without the need for centralization. Usually, peer-to-peer applications are conceptualized as a global network, without any kind of logical segmentation or segregation as far as resource availability is concerned.

Abstract (sommario):
La thèse comporte trois parties. Chaque partie est consacrée à un problème algorithmique important pour les réseaux pair-à-pair. Dans la première partie on analyse des méthodes distribuées cherchant à caractériser les préférences d'usagers: On étend l'applicabilité des méthodes spectrales pour la récupération de structures cachées à des modèles probabilistes de faible rang pour les goûts des usagers. Par la suite, on propose une méthode distribuée basée sur des échanges de messages (message passing) à deux échelles séparées de temps, qui effectue le profilage des usagers d'un réseau pair-à-pai

Abstract (sommario):
Mestrado em Engenharia de Computadores e Telemática<br>Nos últimos anos, a imagem médica em formato digital tem sido uma ferramenta cada vez mais importante quer para o diagnóstico médico quer para o auxílio ao tratamento. Assim, equipamentos de aquisição digital e repositórios de imagem médica são cada vez mais comuns em instituições de saúde, podendo até haver mais que um repositório numa instituição. No entanto, esta proliferação de repositórios leva a que a informação esteja dispersa nos vários locais. Esta dispersão da informação juntamente com as diferenças no armazenamento entre

Abstract (sommario):
Mestrado em Engenharia de Computadores e Telemática<br>As tecnologias peer-to-peer apresentam uma forma interessante de explorar recursos computacionais normalmente desperdiçados. Esta dissertação tem como objectivo avaliar a utilização de tecnologias peer-to-peer como suporte para bibliotecas digitais. Foi utilizada a biblioteca JXTA para criar a rede peer-to-peer. Foi também definida a estratégia para a disponibilização de serviços na rede utilizando um sistema análogo aos tradicionais WebServices baseada na biblioteca JXTA-SOAP.

Abstract (sommario):
Peer-to-Peer (P2P) networks have seen tremendous growth in development and usage in recent times. This attention has brought many developments as well as new challenges to these networks. We will show that agent extensions to P2P networks offer solutions to many problems faced by P2P networks. In this research, an attempt is made to bring together JXTA P2P infrastructure and Jinni, a Prolog based agent engine to form an agent based P2P network. On top of the JXTA, we define simple Java API providing P2P services for agent programming constructs. Jinni is deployed on this JXTA network using an

Abstract (sommario):
xxii, 413 p. : ill.<br>Streaming multimedia content over the Internet is extremely popular mainly due to emerging applications such as IPTV, YouTube and e-learning. All these applications require simultaneous streaming of multimedia content from one or multiple sources to a large number of users. Such applications impose unique requirements in terms of server bandwidth and playback delay which are difficult to achieve in a scalable fashion with the traditional client-server architecture. Peer-to-peer (P2P) overlays offer a promising approach to support scalable streaming applications, that we

Abstract (sommario):
For traditional web servers, available bandwidth decreases as the number of clients increases. This can cause servers to serve files slowly or to become completely overwhelmed when load grows too high. BitTorrent is a peer-to-peer solution to this problem, but it requires manual configuration for each file to be delivered this way. We develop a new system that integrates peer-to-peer file delivery with traditional client-server downloads. Clients initially attempt to download a file from a web server; if this is too slow, they transition to peer-to-peer delivery. Experiments with a prototype s
