QUILT: A Decode/Quantize-Interleave-Transmit Approach to Cooperative Relaying

Christina Fragouli, Suhas Diggavi, Siddhartha Brahma, Ayan Sengupta, I-Hsiang Wang

Physical layer cooperation of a source with a relay can significantly boost the performance of a wireless connection. However, the best practical relaying scheme can vary depending on the relative strengths of the channels that connect the source, relay an ...

Rate allocation and optimized decoding in inter-session network coding

Eirina Bourtsoulatze

Recent advances in data processing and communication systems have led to a continuous increase in the amount of data communicated over today’s networks. These large volumes of data pose new challenges on the current networking infrastructure that only offe ...

System and method for cooperative data streaming

Christina Fragouli, Lorenzo Keller

A system and method for cooperative data streaming are disclosed. According to one embodiment, a system for cooperative data streaming comprises a group of devices comprising at least two devices, which are interested in obtaining the same content from the ...

Understanding population displacements on location-based call records using road data

Marcel Salathé, Udayan Kumar

Large population displacements are usually observed after nature disasters. The best approximations to real world population movement in such a short temporal scale are the users' movements patterns derived from the cell phone usage data. However, due to a ...

A Network Coding Approach to Loss Tomography

Christina Fragouli

Network tomography aims at inferring internal network characteristics based on measurements at the edge of the network. In loss tomography, in particular, the characteristic of interest is the loss rate of individual links and multicast and/or unicast end- ...

Collaborative Housing and the Intermediation of Moral Hazard

Thomas Alois Weber

This paper considers intermediation in a di_erentiated short-term housing market where heterogeneous agents may stay at a hotel or at one of several private hosts' properties, below or above hotel quality. The collaborative-housing market fails when agents ...

Exploiting Common Randomness: a Resource for Network Secrecy

Suhas Diggavi, László Czap, Vinod Malathidevi Prabhakaran

We investigate the problem of secure communication in a simple network with three communicating parties, two distributed sources who communicate over orthogonal channels to one destination node. The cooperation between the sources is restricted to a rate l ...

Distributed Rate Allocation With Intersession Network Coding

Pascal Frossard, Nikolaos Thomos, Eirina Bourtsoulatze

In this paper, we propose a distributed rate allocation algorithm for delay minimal data delivery in overlay networks where multiple sources compete simultaneously for the available network resources. In order to efficiently utilize the network resources, ...

Implementation of a Wireless Mesh Network of Ultra Light MAVs with Dynamic Routing

Dario Floreano, Bixio Rimoldi, Jean-Christophe Zufferey, Alberto Jimenez Pacheco, Yannick Gasser

This paper describes the implementation and characterisation of a mobile ad-hoc network (MANET) of ultra-light intelligent flying robots. The flying nature of the network makes it suitable to collect or disseminate content in urban areas or challenging ter ...

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.
