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.

On broadcast and agreement in mobile ad hoc networks

Yoav Sasson

This thesis studies communication and agreement protocols in wireless ad hoc networks from both theoretical and practical perspectives. The last decade has given rise to the rapid growth of wireless telecommunications such as cellular mobile phone networks ...

Chain-Based Anonymous Routing for Wireless Ad Hoc Networks

Reza Shokri

Wireless ad hoc networks are so vulnerable to passive attacks and eavesdropping adversaries due to their shared medium which makes network traffic easy to capture and analyze. Therefore, security and privacy protections are of extreme importance for protoc ...

GossiCrypt: Wireless Sensor Network Data Confidentiality Against Parasitic Adversaries

Jean-Pierre Hubaux, Panagiotis Papadimitratos, Jun Luo

Wireless sensor networks are already deployed in numerous occasions. As this technology matures towards wider adoption, security will become an increasingly important requirement. However, resource and cost constraints for the low-complexity sensor nodes r ...

Thwarting selfish and malicious behavior in wireless networks

Mario Cagalj

Security is at the core of any communication system and, in particular, of wireless (radio) networks. In this thesis, we focus on three important security aspects in the framework of wireless networks: selfish (noncooperative) behavior at the Medium Access ...

Towards reliable communication and agreement in mobile ad-hoc networks

David Cavin

During the last decade, the number of wireless devices like digital organizers, mobile phones and laptop computers has drastically increased. At the same time, several technologies, like Bluetooth, GPRS, or WiFi have become mature and offer a high-performa ...

A Network Coding Approach to Energy Efficient Broadcasting: from Theory to Practice

Jean-Yves Le Boudec, Christina Fragouli, Jörg Widmer

We show that network coding allows to realize energy savings in a wireless ad-hoc network, when each node of the network is a source that wants to transmit information to all other nodes. Energy efficiency directly affects battery life and thus is a critic ...

Reliable Broadcast in Wireless Mobile Ad Hoc Networks

André Schiper, David Cavin, Yoav Sasson

We propose a single source reliable broadcasting algorithm for linear grid-based networks where a message is guaranteed to be delivered to all the nodes of the network. The nodes are mobile and can move from one grid point to another. The solution does not ...

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 ...

Break WEP Faster with Statistical Analysis

Rafik Chaabouni

The Wired Equivalent Protocol is nowadays considered as unsafe. However the only academic research that tries to break WEP has been done by Fluhrer, Mantin and Shamir, who have published a report on a specific attack. Nevertheless, an unknown person under ...
