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.

Analysis and Enhancement of CSMA/CA With Deferral in Power-Line Communications

Patrick Thiran, Julien Pierre Sacha Herzen, Christina Vlachou

Power-line communications are employed in home networking to provide easy and high-throughput connectivity. The IEEE 1901, the MAC protocol for power-line networks, employs a CSMA/CA protocol similar to that of 802.11, but is substantially more complex, wh ...

Tornado Attack on RC4 with Applications to WEP & WPA

Serge Vaudenay, Martin Vuagnoux, Pouyan Sepehrdad, Petr Susil

In this paper, we construct several tools for building and manipulating pools of biases in the analysis of RC4. We report extremely fast and optimized active and passive attacks against IEEE 802.11 wireless communication protocol WEP and a key recovery and ...

UAVs using Bayesian Optimization to LocateWiFi Devices

Bixio Rimoldi, Stefano Rosati, Mohammad Emtiyaz Khan, Mattia Carpin

We address the problem of localizing non-collaborative WiFi devices in a large region. Our main motive is to localize humans by localizing their WiFi devices, e.g. during search-and-rescue operations after a natural disaster. We use an active sensing appro ...

Learning Wi-Fi Performance

Julien Pierre Sacha Herzen, Nidhi Hegde

Accurate prediction of wireless network performance is important when performing link adaptation or resource allocation. However, the complexity of interference interactions at MAC and PHY layers, as well as the vast variety of possible wireless configurat ...

Fractionally Spaced Complex Sub-Nyquist Sampling for Multi-Gigabit 60 GHz Wireless Communication

Andreas Peter Burg, Nicholas Alexander Preyss

A novel analog front-end architecture based on complex sub-Nyquist sampling for the intermediate frequency (IF) stage of a mmWave receiver is proposed. With this front-end, the use of a wideband hybrid coupler and two half-rate analog-to-digital converters ...

IEEE2015

A complete digital synchronization architecture for an IEEE 802.11ad compliant 60 GHz receiver is presented. The characteristics of mmWave systems require a holistic view on the problem of parameter estimation, such that not each parameter is dealt with on ...

Integration of IEEE C37.118 and publish/subscribe communication

Mario Paolone, Paolo Romano, Teklemariam Tsegay Tesfay

IEEE C37.118 is the current standard for synchrophasor measurements in power systems. It defines the measurement method and communication protocols for the entities in a synchrophasor network. The standard offers two different modes for client-server commu ...

Drones InSecurity

This project is about testing the security of casual/commercial drones. For this, we tested drones from the company Parrot, but the conclusions apply to all drones based on WiFi controllers. To test drones security, the project was divided in two parts. Th ...
