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.

Self-organizing structured peer-to-peer overlay networks

A peer-to-peer overlay network is a logical network, built on top of a physical network. In contrast to classical client-server distributed architectures, peer-to-peer overlay networks allow location of resources without centralized control. Existing overl ...

Congestion Control for Distributed Hash Tables

Jean-Yves Le Boudec, Karl Aberer, Fabius Klemm

Distributed Hash Tables (DHTs) provide a scalable mechanism for mapping identifiers to socket addresses. As each peer in the network can initiate lookup requests, a DHT has to process concurrently a potentially very large number of requests. In this paper, ...

Using End-to-End Data to Infer Lossy Links in Sensor Networks

Patrick Thiran, Xuan Hung Nguyen

Compared to wired networks, sensor networks pose two additional challenges for monitoring functions: they support much less probing traffic, and they change their routing topologies much more frequently. We propose therefore to use only end-to-end applicat ...

Distributed processing over adaptive networks

Ali H. Sayed

Distributed adaptive algorithms are proposed based on incremental and diffusion strategies. Adaptation rules that are suitable for ring topologies and general topologies are described. Both distributed LMS and RLS implementations are considered in order to ...

Failure Location in Transparent Optical Networks: The Asymmetry Between False and Missing Alarms

Patrick Thiran, Xuan Hung Nguyen

Failure location in transparent optical networks is difficult because of the large amount of alarms that a failure can trigger and because of corrupted alarms. One problem that network operators often face is how to set the thresholds in monitoring devices ...

On the Throughput Improvement due to Limited Complexity Processing at Relay Nodes

Christina Fragouli

We consider a source that transmits information to a receiver by routing it over a communication network represented by a graph and examine rate benefits that finite complexity processing at the intermediate nodes may offer. We show that there exist config ...

A Location Based Routing Method for Mobile Ad Hoc Networks

Jean-Yves Le Boudec, Ljubica Blazevic

Using location information to help routing is often proposed as a means to achieve scalability in large mobile ad-hoc networks. However, location based routing is difficult when there are holes in the network topology and nodes are mobile or frequently dis ...

A framework for component-based construction

Joseph Sifakis

We present an overview of results developed mainly at Verimag, by the author and his colleagues, on a framework for component-based construction, characterized by the following: the behavior of atomic components is represented by transition systems; compon ...

An improved approximation algorithm for virtual private network design

Friedrich Eisenbrand

Virtual private network design deals with the reservation of capacities in a network, such that the nodes can share communication. Each node in the network has associated upper bounds on the amount of flow that it can send to the network and receive from t ...

Synchronizing Method for Impulse Radio Network

Jean-Yves Le Boudec, Alaeddine El Fawal

In IR (Impulse Radio) network, the conventional synchronization (also called signal acquisition) method becomes inefficient and results in a certain failure of synchronization when concurrent transmissions are allowed without controlling their powers. The ...
