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.

A Tutorial-Cum-Survey on Percolation Theory With Applications in Large-Scale Wireless Networks

Ainur Zhaikhan

Connectivity is an important key performance indicator and a focal point of research in large-scale wireless networks. Due to path-loss attenuation of electromagnetic waves, direct wireless connectivity is limited to proximate devices. Nevertheless, connec ...

Internet blackouts are challenging environments for anonymity and censorship resistance. Existing popular anonymity networks (e.g., Freenet, I2P, Tor) rely on Internet connectivity to function, making them impracticable during such blackouts. In such a set ...

Space, people, networks

Selena Savic

In this thesis, I investigate wireless communication from an architectural perspective. I am using design prototypes to explore possibilities for interaction and designing with wirelessness in mind. The public primarily regards wireless networking technolo ...

Track Me If You Can: On the Effectiveness of Context-based Identifier Changes in Deployed Mobile Networks

Jean-Pierre Hubaux, Imad Aad, Murtuza Jadliwala, Igor Bilogrevic, Valtteri Niemi, Laurent Bindschaedler

Location privacy is a major concern in an increasingly connected and highly pervasive network of mobile users. Novel location-based applications and device-to-device services (on these mobile devices) are gaining popularity, but at the same time, these ser ...

Distributed Authentication in Anonymous Mobile Communities

Hamza Harkous

With the recent boom in smartphones technology, online social networks are going mobile. This trend urged phone manufacturers and social networking companies to seek novel business strategies to monetize from these new "gateways" and to give the users ...

Empirical Performance Evaluation of Data Dissemination Mechanisms for Spot Applications

Jean-Yves Le Boudec, Alaeddine El Fawal, Adel Aziz

We evaluate, by measurements on a real testbed, the performance of networking services required for spot applications. We call a “spot application” an application for smartphones (such as “Ad-hoc Flash Sales”) that disseminates information in a local neigh ...

Secure key exchange in wireless networks

Christina Fragouli, László Czap

We investigate the problem of exchanging a se- cret key within a group of wireless devices. In particular, we are interested in information theoretically secure key exchange schemes that enable honest nodes of a multi-hop network to establish a secret grou ...

Distributed Delay-Power Control Algorithms for Bandwidth Sharing in Wireless Networks

Nicolas Gabriel Gast

In this paper, we formulate a delay-power control (DPC) scheme for wireless networking, which efficiently balances delay against transmitter power on each wireless link. The DPC scheme is scalable, as each link autonomously updates its power based on the i ...
