An Evaluation of Media-Oriented Rate Selection Algorithm for Multimedia Transmission in MANETs

We focus on the optimization of real-time multimedia transmission over 802.11-based ad hoc networks. In particular, we propose a simple and efficient cross-layer mechanism that considers both the channel conditions and characteristics of the media for dyna ...

Probabilistic Reliable Multicast in Ad Hoc Networks

Jean-Pierre Hubaux, Jun Luo, Patrick Eugster

When striving for reliability, multicast protocols are most commonly designed as deterministic solutions. Such an approach seems to make the reasoning about reliability guarantees (traditionally binary "all-or-nothing"- like) in the face of packet losses a ...

PILOT: ProbabilistIc Lightweight grOup communication sysTem for Mobile Ad Hoc Networks

Jean-Pierre Hubaux, Jun Luo, Patrick Eugster

Providing reliable group communication is an ever recurring issue in distributed settings. In mobile ad hoc networks, this issue becomes more significant since all nodes act as peers, while the issue gets even more challenging due to highly dynamic and unp ...

Towards Flexible Finite-State Machine Based Protocol Composition

André Schiper, Sergio Mena, Nils Richard Ekwall, Stefan Pleisch

Group communication provides primitives that ensure reliable and ordered delivery of messages to a group of destinations. It is an important building block for replicated fault-tolerant applications such as replicated databases. In the past, most group com ...

Evaluation of a Routing Architecture for Wireless Messaging Ad-Hoc Networks

Mark Felegyhazi, Megha Goel

The Short Messaging Service(SMS) which has become very popular in cellular networks is very highly priced. We show in this paper how self-organizing ad-hoc networks can be used to provide the short messaging service, at a much lower price. We propose a rou ...

Analysis of a subdomain-based error estimator for finite element approximations of elliptic problems

Fabio Nobile

In this article we analyze a subdomain residual error estimator for finite element approximations of elliptic problems. It is obtained by solving local problems on patches of elements in weighted spaces and provides an upper bound on the energy norm of the ...

Noise-Robust Multi-Stream Fusion for Text-Independent Speaker Authentication

Samy Bengio, Norman Hoon Thian Poh

Multi-stream approaches have proven to be very successful in speech recognition tasks and to a certain extent in speaker authentication tasks. In this study we propose a noise-robust multi-stream text-independent speaker authentication system. This system ...

Dense Matching of Multiple Wide-baseline Views

Christoph Strecha

This paper describes a PDE-based method for dense depth extraction from multiple wide-baseline images. Emphasis lies on the usage of only a small amount of images. The integration of these multiple wide-baseline views is guided by the relative confidence t ...

Graph Chatbot

Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
