Happiness and Travel Mode Switching: Findings from a Swiss Public Transportation Experiment

Michel Bierlaire, Vincent Kaufmann, Regina Witter

We present results from a recent experiment conducted in Switzerland that studies the effects of a temporary change in the mode of travel to work on travel happiness and mode switching. The primary aim is to study the dynamics in travel satisfaction rating ...

Exploiting the Path Propagation Time Differences in Multipath Transmission with FEC

Maciej Kurant

We consider a transmission of a delay-sensitive data stream (e. g., a video call) from a single source to a single destination. The reliability of this transmission may suffer from bursty packet losses - the predominant type of failures in today's Internet ...

Distributed top-k aggregation queries at large

Sebastian Michel

Top-k query processing is a fundamental building block for efficient ranking in a large number of applications. Efficiency is a central issue, especially for distributed settings, when the data is spread across different nodes in a network. This paper intr ...

Exploiting the Path Propagation Time in Multipath Transmission with FEC

We consider a transmission of a delay-sensitive data stream from a single source to a single destination. The reliability of this transmission may suffer from bursty packet losses - the predominant type of failures in today's Internet. An effective and wel ...

Low-complexity Algorithms for Energy Efficient Broadcasting in Wireless Networks

Jean-Yves Le Boudec, Christina Fragouli, Jörg Widmer

We consider the problem of broadcasting in an ad hoc wireless network, where all nodes of the network are sources that want to transmit information to all other nodes. Our figure of merit is energy efficiency, a critical design parameter for wireless net- ...

Efficient Broadcasting Using Network Coding

Jean-Yves Le Boudec, Christina Fragouli, Jörg Widmer

We consider the problem of broadcasting in an ad-hoc wireless network, where all nodes of the network are sources that want to transmit information to all other nodes. Our figure of merit is energy efficiency, a critical design parameter for wireless netwo ...

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 ...

Anypath routing

Henri Julien Dubois-Ferrière

In many networks, it is less costly to transmit a packet to any node in a set of neighbors than to one specific neighbor. A well-known instance is with unreliable wireless links, where the probability that at least one node out ofnreceives a packet increas ...

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 significant 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 ...

Conditional Bit Error Rate for an Impulse Radio UWB Channel with Interfering Users

Jean-Yves Le Boudec, Ruben Merz

We consider a multi-user impulse radio UWB physical layer in a multipath environment. We propose a fast and efficient method to compute the conditional bit error rate (BER), given some realizations of the channels from source/interferer to destination, and ...

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.
