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.

Key agreement over a radio link

Jean-Pierre Hubaux, Mario Cagalj

We present a simple, and yet powerful, technique for key establishment over a radio link in peer-to-peer networks. Our approach is based on the Diffie-Hellman key agreement protocol. This protocol is known to be vulnerable to the ``man-in-the-middle" attac ...

An Artificial Immune System Approach to Misbehavior Detection in Mobile Ad-Hoc Networks

Jean-Yves Le Boudec, Slavisa Sarafijanovic

In mobile ad-hoc networks, nodes act both as terminals and information relays, and participate in a common routing protocol, such as Dynamic Source Routing (DSR). The network is vulnerable to routing misbehavior, due to faulty or malicious nodes. Misbehavi ...

Towards Perceptually Driven Segmentation Evaluation Metrics

Touradj Ebrahimi, Elisa Drelie Gelasca

To be reliable, an automatic segmentation evaluation metric has to be validated by subjective tests. In this paper, a formal protocol for subjective tests for segmentation quality assessment is presented. The most common artifacts produced by segmentation ...

Extremum feedback with partial knowledge

Jörg Widmer

A scalable feedback mechanism to solicit feedback from a potentially very large group of networked nodes is an important building block for many network protocols. Multicast transport protocols use it for negative acknowledgements and for delay and packet ...

The BANCA Database and Evaluation Protocol

Jean-Philippe Thiran, Vlad Popovici

In this paper we describe the acquisition and content of a new large, realistic and challenging multi-modal database intended for training and testing multi-modal verification systems. The BANCA database was captured in four European languages in two modal ...

Applying Fondue to Specify a Drink Vending Machine

Shane Sendall

The purpose of the paper is to present our approach for specifying system behavior during analysis, part of the Fondue software development method. The approach is exempli ed on a case study, a Drink Vending Machine (DVM). It is based on Operation Schemas ...

Robust TCP Connections for Fault Tolerant Computing

André Schiper, Nils Richard Ekwall

When processes on two different machines communicate, they most often do so using the TCP protocol. While TCP is appropriate for a wide range of applications, it has shortcomings in other application areas. One of these areas is fault tolerant distributed ...

Cooperation in Multi-hop Cellular Networks

Jean-Pierre Hubaux, Naouel Ben Salem, Levente Buttyan

Naouel Ben Salem, Levente Buttyan, Jean-Pierre Hubaux and Markus Jakobsson abstract: In multi-hop cellular networks, the existence of a communication link between the mobile station and the base station is not required: a mobile station that has no direct ...

Route Driven Gossip: Probabilistic Reliable Multicast in Ad Hoc Networks

Jean-Pierre Hubaux, Jun Luo, Patrick Eugster

Traditionally, reliable multicast protocols are deterministic in nature. It is precisely this determinism which tends to become their limiting factor when aiming at reliability and scalability, particularly in highly dynamic networks, e.g., ad hoc networks ...
