Scalable Peer-to-Peer Web Retrieval with Highly Discriminative Keys

Karl Aberer, Martin Rajman, Vinh Toan Luu, Ivana Podnar, Fabius Klemm

The suitability of Peer-to-Peer (P2P) approaches for full-text web retrieval has recently been questioned because of the claimed unacceptable bandwidth consumption induced by retrieval from very large document collections. In this contribution we present a ...

SoS: self-organizing substrates

Anwitaman Datta

Large-scale networked systems often, both by design or chance exhibit self-organizing properties. Understanding self-organization using tools from cybernetics, particularly modeling them as Markov processes is a first step towards a formal framework which ...

Analysis of a Reputation System for Mobile Ad-Hoc Networks with Liars

Jean-Yves Le Boudec, Jochen Mundinger

Using decentralized reputation systems is a promising approach to ensuring cooperation and fairness in Mobile Ad-Hoc Networks. However, they are vulnerable to liars and robustness has not been analyzed in detail. With our work, we provide a first step to t ...

Principles of Query-Adaptive Optimal Replication in DHTs

Karl Aberer, Anwitaman Datta, Wolfgang Nejdl

This paper focuses on replication in DHT based structured overlay networks, and presents a theoretical framework for optimal replication in such networks with respect to query frequency. In particular, we determine the optimal replication factor for query- ...

Experimental evaluation results of an advanced DHT-based peer-to-peer system

Karl Aberer, Manfred Hauswirth, Roman Schmidt

P-Grid is a decentralized DHT-based peer-to-peer system with logarithmic search complexity. As it is intended to provide a platform for distributed information management beyond mere file-sharing it supports an update functionality with lazy consistency gu ...

Controlled Use of Excess Backbone Bandwidth for Providing New Services in IP-Over-WDM Networks

Patrick Thiran

We study an approach to quality-of-service (QoS) that offers end-users the choice between two service classes defined according to their level of transmission protection. The fully protected (FP) class offers end-users a guarantee of survivability in the c ...

PIX-Grid: A Platform for P2P photo exchange

Karl Aberer, Manfred Hauswirth, Philippe Cudré-Mauroux, Anwitaman Datta

The proliferation of digital camera devices (stand-alone or combined with cell phones), new protocols such as MMS and the desire of people to com-municate and share their experience call for new systems to support these needs in new Internet-scale infrastr ...

Gridella: an open and efficient Gnutella-compatible Peer-to-Peer System based on the P-Grid approach

Roman Schmidt

This thesis describes the Peer-to-Peer Application Gridella. The decentralized architecture of P2P systems enables each peer to fulfill search requests solely by local interactions. The system described in this thesis scales to high numbers of peers and da ...
