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.

Secure Positioning in Wireless Networks

Jean-Pierre Hubaux, Srdan Capkun

So far, the problem of positioning in wireless networks has been studied mainly in a nonadversarial setting. In this paper, we analyze the resistance of positioning techniques to position and distance spoofing attacks. We propose a mechanism for secure pos ...

Advances in indoor Location

Phillip Tomé

This paper presents the research activities carried out within the scope of the Liaison project. Most of the work has been performed on WiFi location. WiFi is nowadays widely deployed in buildings such as hotels, hospitals, airports, train stations, public ...

Systematic Design Flow for Dynamic Data Management in Visual Texture Decoder of MPEG-4

David Atienza Alonso, Miguel Peon Quiros

There is a clear trend of future embedded systems in moving toward wireless, multimedia, multi-functional and ubiquitous applications. This emerges new challenges in the existing solutions on performance, power, flexibility and costs, calling for innovatio ...

Custom GPS-Correction Server for Real-Time Trajectography

Hervé Gontran

Centimeter-level real-time kinematic (RTK) positioning is one of the most widely used surveying techniques. Broadcasting GPS-RTK corrections via Internet-based services has become a new communication procedure to achieve “instantaneous” positioning with hi ...

Low-complexity energy-efficient broadcasting in wireless ad-hoc networks using network coding

Jean-Yves Le Boudec, Christina Fragouli, Jörg Widmer

Energy efficiency, i.e., the amount of battery energy consumed to transmit bits across a wireless link, is a critical design parameter for wireless ad-hoc networks. We examine the problem of broadcasting information to all nodes in an ad-hoc network, when ...

Managing Heterogeneous Wireless Environments via Hotspot Servers

Giovanni De Micheli

Wireless communication today supports heterogeneous wireless devices with a number of different wireless network interfaces (WNICs). A large fraction of communication is infrastructure based, so the wireless access points and hotspot servers have become mo ...

Secure positioning of wireless devices with application to sensor networks

Jean-Pierre Hubaux, Srdan Capkun

So far, the problem of positioning in wireless networks has been mainly studied in a non-adversarial setting. In this work, we analyze the resistance of positioning techniques to position and distance spoofing attacks. We propose a mechanism for secure pos ...

Secure Route Discovery for QoS-Aware Routing in Ad Hoc Networks

Panagiotis Papadimitratos

We address the problem of securing the route discovery for Quality-of- Service (QoS)-aware routing in ad hoc networks. We provide a specification of secure route discovery for QoS-aware routing. We propose a reactive secure routing protocol, SRP-QoS, to de ...

Reputation-based Wi-Fi Deployment

Jean-Pierre Hubaux, Naouel Ben Salem

Wi-Fi networks have a very strong potential: They are easy to deploy, they use unlicensed frequencies and they provide Internet connectivity that is several times faster than by cable modem. However, two major problems still need to be solved: the lack of ...

Automatic Management of 802.11 Access Points

Sacha Varone, Frédéric Jean-Michel Aviolat, Daniel Rossier

The automatic configuration of Access Points (APs) is a new subject, since the Wi-Fi technology, which underlies hotspots by a wireless local area network, appears on the world market in 2001. The first market relevance has been in 2002. APs channel assign ...
