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.

Security and Cooperation in Wireless Networks

Jean-Pierre Hubaux, Levente Buttyan

According to most technology pundits, progress in wireless and sensor networks will lead us into a world of ubiquitous computing, in which myriads of tiny, untethered sensors and actuators will communicate with each other. Information technology will thus ...

Diversity embedding for broadband communication

Sanket Dusad

Given uncertainty in environment, a conservative approach is to design for the worst case, leading to a game-theoretic situation where the environment is controlled by an adversary. However, in many cases, the uncertainty arises from randomness, not an adv ...

On Wireless Social Community Networks

Jean-Pierre Hubaux, Mark Felegyhazi, Julien Freudiger, Peter Marbach

Wireless social community networks are emerging as a new alternative to provide wireless data access in urban areas. By relying on users in the network deployment, a wireless community can rapidly deploy a high-quality data access infrastructure in an inex ...

Non-cooperative behavior in wireless networks

Mark Felegyhazi

Existing cellular networks are centrally managed and require a tremendous initial investment. With the advancement of new wireless technologies, the operators of traditional networks have to face new competition. New technologies make it possible to provid ...

Low delay video coding

Analogue wireless cameras have been employed for decades, however they have not become an universal solution due to their difficulties of set up and use. The main problem is the link robustness which mainly depends on the requirement of a line-of-sight vie ...

A Cooperative Backup System

Sameh Mohamed Elnikety

We present a novel peer-to-peer backup technique that allows computers connected to the Internet to back up their data cooperatively: Each computer has a set of partner computers, which collectively hold its backup data. In return, it holds a part of each ...

Space-Time Coding for Broadband Wireless Transmission

Christina Fragouli

We present an overview of research activities on space-time coding for broadband wireless transmission performed at AT & T Shannon Laboratory over the past two years. The emphasis is on physical layer modem algorithms such as channel estimation, equalizati ...

Approaching the Rate-Distortion Limit with Spatial Coupling, Belief propagation and Decimation

Nicolas Macris, Vahid Aref, Marc Vuffray

We investigate an encoding scheme for lossy compression of a binary symmetric source based on simple spatially coupled Low-Density Generator-Matrix codes. The degree of the check nodes is regular and the one of code-bits is Poisson distributed with an aver ...
