Maximizing the Delivery of MPR Broadcasting under Realistic Physical Layer Assumptions

It is now commonly accepted that the unit disk graph used to model the physical layer in wireless networks does not reflect real radio transmissions, and that a more realistic model should be considered for experimental simulations. Previous work on realis ...

Multiuser successive refinement and multiple description coding

Suhas Diggavi, Jun Chen

In this correspondence, we consider the multiuser successive refinement (MSR) problem, where the users are connected to a central server via links with different noiseless capacities, and each user wishes to reconstruct in a successive-refinement fashion. ...

Development of novel SU-8 based nanoimprint lithography

Shenqi Xie, Rong Yang

We present two kinds of novel nanoimprint lithography techniques based on SU-8 photoresist with single layer and tri-layer approaches. The imprint templates with high aspect ratio were first fabricated by electron beam lithography (EBL) and reactive ion et ...

AFEX: An Automated Fault Explorer for Faster System Testing

George Candea, Lorenzo Keller, Paul Dan Marinescu

Fault injection is an often overlooked component of the software test cycle, yet it is critical for building robust systems. The main reasons for this neglect are ineffectual tools, an overwhelmingly large number of possible faults to inject, and extensive ...

On feedback for network coding

Christina Fragouli

In this paper we examine possible ways that feedback can be used, in the context of systems with network coding capabilities. We illustrate, through a number of simple examples, that use of feedback can be employed for parameter adaptation to satisfy QoS r ...

A Simulation Model for Wireless Sensor Networks Based on TOSSIM

Giovanni De Micheli, David Atienza Alonso, Francisco Javier Rincon Vallejos, Alexandru Emilian Susu

Wireless Sensor Networks (WSNs) are composed of a large number of very small devices used for biomedical or environmental monitoring applications. These devices measure various natural processes at different locations, and cooperate in order to aggregate t ...

Compositional reflectance and transmittance model for multilayer specimens

Roger Hersch, Mathieu Hébert

We propose a compositional model for predicting the reflectance and the transmittance of multilayer specimens composed of layers having possibly distinct refractive indices. The model relies on the laws of geometrical optics and on a description of the mul ...

An analytic finite capacity queueing network model capturing blocking, congestion and spillbacks

Michel Bierlaire, Carolina Osorio Pizano

Analytic queueing network models often assume infinite capacity for all queues. For real systems this infinite capacity assumption does not hold, but is often maintained due to the difficulty of grasping the between-queue correlation structure present in f ...

Error and Attack Tolerance of Layered Complex Networks

Patrick Thiran, Patric Hagmann, Maciej Kurant

Many complex systems may be described by not one but a number of complex networks mapped on each other in a multi-layer structure. Because of the interactions and dependencies between these layers, the state of a single layer does not necessarily reflect w ...

Message Passing in Semantic Peer-to-Peer Overlay Networks

Karl Aberer, Philippe Cudré-Mauroux

Peer-to-Peer (P2P) systems rely on machine-to-machine ad-hoc communications to offer services to a community. Contrary to the classical client-server architecture, P2P systems consider all peers, i.e., all nodes participating in the network, as being equal ...

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.
