Frugal Event Dissemination in a Mobile Environment

This paper describes an event dissemination algorithm that implements a topic-based publish/subscribe interaction abstraction in mobile ad-hoc networks (MANETs). Our algorithm is frugal in two senses. First, it reduces the total number of duplicates and pa ...

Binary Versus Analogue Path Monitoring in IP Networks

Patrick Thiran, Xuan Hung Nguyen

Monitoring systems that can detect path outages and periods of degraded performance are important for many distributed applications. Trivial pairwise probing systems do not scale well and cannot be employed in large networks. To build scalable path monitor ...

On Survivable Routing of Mesh Topologies in IP-over-WDM Networks

Patrick Thiran, Maciej Kurant

Failure restoration at the IP layer in IP-over-WDM networks requires to map the IP topology on the WDM topology in such a way that a failure at the WDM layer leaves the IP topology connected. Such a mapping is called survivable. Finding a survivable mappin ...

Single and Multi-Hop ARQ in Sensor Networks

Martin Vetterli, Henri Julien Dubois-Ferrière

We present a novel error-correction scheme for sensor networks called Multi-hop Hybrid ARQ (MHARQ). Rather than immediately discard a received corrupt packet, a node buffers it. When two corrupt versions of a packet have been received, a procedure attempts ...

Deux applications de processus ponctuels aux réseaux de communication

Patrick Thiran, Olivier Dousse, Xuan Hung Nguyen

This paper (in Frensh) summarizes recent results obtained by using shot noise processes for two applications in communication networks: first, TCP/IP traffic models for backbone networks; and next the study of connectivity under rate constraints in wireles ...

Real-time interaction over the Internet

Christophe Salzmann

This dissertation studied real-time interaction over the Internet (RTI2) in the context of remote experimentation where there is typically a person at the client side interacting with physical equipments at the server side. Remote experimentations of mecha ...

Assessing the Crash-Failure Assumption of Group Communication Protocols

André Schiper, Sergio Mena

Designing and correctly implementing Group Communication Systems (GCSs) is notoriously difficult. Assuming that processes fail only by crashing provides a powerful means to simplify the theoretical development of these systems. When making this assumption, ...

Evaluating scheduling policies for fine-grain communication protocols on a cluster of SMPs

Babak Falsafi, David Wood

Distributed-memory parallel computers and networks of workstations (NOWs) both rely on efficient communication over increasingly high-speed networks. Software communication protocols are often the performance bottleneck. Several current and proposed parall ...

Real-Time Interaction over the Internet: Model for QOS Adaptation

Denis Gillet, Christophe Salzmann, Philippe Müllhaupt

Real-time Interaction over the Internet (RTI2) is an Internet service that is required typically by remote experimentation applications. From a quality of service (QoS) point of view, RTI2 has constraints that differ from usual real-time multimedia service ...

Packet Combining in Sensor Networks

Martin Vetterli, Henri Julien Dubois-Ferrière

This paper presents the Simple Packet Combining (SPaC) error-correction scheme for wireless sensor networks. Nodes buffer corrupt packets, and when two or more corrupt versions of a packet have been received, a packet combining procedure attempts to recove ...

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.
