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 Publish/Subscribe Approach to Processing Continuous Queries over Sensor Streams

Oana Anca Jurca

With technological advances, the sources of available information have become more and more diverse. Recently, a new source of information has gained growing importance: sensor data. Sensors are devices sensing their environment in various ways and reporti ...

Routing and search on large scale networks

Dominique Florian Tschopp

In this thesis, we address two seemingly unrelated problems, namely routing in large wireless ad hoc networks and comparison based search in image databases. However, the underlying problem is in essence similar and we can use the same strategy to attack t ...

Ultra Low Power Communication Protocols for UWB Impulse Radio Wireless Sensor Networks

Jérôme Rousselot

This thesis evaluates the potential of Ultra Wideband Impulse Radio for wireless sensor network applications. Wireless sensor networks are collections of small electronic devices composed of one or more sensors to acquire information on their environment, ...

Castor: Scalable Secure Routing for Ad Hoc Networks

Karl Aberer, Panagiotis Papadimitratos, Marcin Poturalski, Wojciech Galuba, Zoran Despotovic

Wireless ad hoc networks are inherently vulnerable, as any node can disrupt the communication of potentially any other node in the network. Many solutions to this problem have been proposed. In this paper, we take a fresh and comprehensive approach that ad ...

Space-time codes of maximal size in MIMO communication

Daniele Rotanzi

Reliability of any communication technology, such as wireless channels, can be measured by the probability of incorrect decoding of a sent message. The lower is this probability the more reliable is the technology. The main problem in wireless communicatio ...

Erased Secrets: Practical Information-Theoretic Group Secrecy

Christina Fragouli, Suhas Diggavi, Mahdi Jafari Siavoshani, Uday Kiran Pulleti

We consider the scenario where a group of wireless nodes want to exchange a secret key, such that no eavesdropper can guess the key. Today, this can be achieved using publickey cryptography, e.g., the Diffie-Hellman or the RSA keyexchange algorithms. Howev ...

Collaborative Transportation Systems

We propose a new class of applications for Intelligent Transportation Systems (ITSs), called collaborative transportation applications that aim at solving transportation problems such as congestion and parking. Specifically, we define two applications: Sma ...

Information Theoretic Operating Regimes of Large Wireless Networks

Olivier Lévêque, Ayfer Özgür Aydin

In analyzing the point-to-point wireless channel, insights about two qualitatively different operating regimes --bandwidth- and power-limited-- have proven indispensable in the design of good communication schemes. In this paper, we propose a new scaling l ...

Game Theory in Communications

Vojislav Gajic

Multi-user communication theory typically studies the fundamental limits of communication systems, and considers communication schemes that approach or even achieve these limits. The functioning of many such schemes assumes that users always cooperate, eve ...

On the Tradeoff between Trust and Privacy in Wireless Ad Hoc Networks

Jean-Pierre Hubaux, Maxime Raya, Reza Shokri

As privacy moves to the center of attention in networked systems, and the need for trust remains a necessity, an important question arises: How do we reconcile the two seemingly contradicting requirements? In this paper, we show that the notion of data-cen ...
