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.

QoSNC: A Novel Approach to QoS-Based Network Coding for Fixed Networks

Amir Hesam Salavati

In this paper, we present a decentralized algorithm to find minimum cost quality of service (QoS) flow subgraphs in network coded multicast schemes. The main objective is to find minimum cost subgraphs that also satisfy user-specified QoS constraints, spec ...

Centralized Versus Decentralized Control - A Solvable Stylized Model in Transportation

Olivier Gallay

To analyze the potential outcomes resulting from interaction between autonomous decision-making "smart parts" in logistics networks, we propose here an exactly solvable stylized model that is able to quantify how much the dynamics can be enhanced by (fully ...

Privacy-aware and highly-available OSN profiles

Karl Aberer, Rammohan Narendula

The explosive growth of online social networks (OSNs) and their wide popularity suggest the impact of OSNs on today's Internet. At the same time, concentration of vast amount of personal information within a single administrative domain causes critical pri ...

Distributed average consensus for wireless sensor networks

Florence Bénézit

Wireless sensor networks have emerged a few years ago, enabling large scale sensing at low cost. There are many interesting problems related to this new sensing tool: designing robust and small hardware, defining adapted routing protocols, minimizing the e ...

Multi-Agent Adaptive Mechanism Leading to Optimal Real-Time Load Sharing

Max-Olivier Hongler, Olivier Gallay

We propose a new real-time load sharing policy (LSP), which optimally dispatches the incoming workload according to the current availability of the operators. Optimality means here that the global service permanently requires the engagement of a minimum nu ...

Decentralized Network Coding

Christina Fragouli, Emina Soljanin

This paper proposes deterministic algorithms for decentralized network coding. Decentralized coding allows to locally specify the coding operations at network nodes without knowledge of the overall network topology, and to accommodate future changes in the ...

Token-based Atomic Broadcast using Unreliable Failure Detectors

André Schiper, Nils Richard Ekwall

Many atomic broadcast algorithms have been published in the last twenty years. Token-based algorithms represent a large class of these algorithms. Interestingly, all the token-based atomic broadcast algorithms rely on a group membership service, i.e., none ...

Networked Slepian-Wolf: Theory and Algorithms

Martin Vetterli, Razvan Cristescu

In this paper, we consider the minimization of a relevant energy consumption related cost function in the context of sensor networks where correlated sources are generated at various sets of source nodes and have to be transmitted to some set of sink nodes ...
