Mapping and Physical Planning of Networks-on-Chip Architectures with Quality-of-Service Guarantees

Giovanni De Micheli, Luca Benini, Srinivasan Murali

Networks on Chips (NoCs) have evolved as the communication design paradigm of future Systems on Chips (SoCs). In this work we target the NoC design of complex SoCs with heterogeneous processor/memory cores, providing Quality-of-Service (QoS) for the applic ...

"Pay bursts only once" does not hold for non-FIFO Guaranteed Rate nodes

Jean-Yves Le Boudec, Gianluca Rizzo

We demonstrate that, contrary to what is generally believed, the existing end-to-end delay bounds apply only to GR nodes that are FIFO per flow. We show this by exhibiting a counter-example. Then we show that the proof of the existing bounds has a subtle, ...

Guided-wave micro-electro-mechanical systems (MEMS) optical switches for telecommunication applications

Roland Guerre

The present thesis deals with Micro-Electro-Mechanical Systems (MEMS) optical switches for telecommunication applications. The aim is to study new type of microsystems for guided-wave optical switching applications. Two projects have been investigated. The ...

Tissu numérique cellulaire à routage et configuration dynamiques

Yann Thoma

In the design of new machines or in the development of new concepts, mankind has often observed nature, looking for useful ideas and sources of inspiration. The design of electronic circuits is no exception, and a considerable number of realizations have d ...

Rate Adaptation, Power Adaptation and Mutual Exclusion in Variable Rate Wireless Networks

Jean-Yves Le Boudec

We consider the joint design of rate adaptation, power adaptation and mutual exclusion for the MAC layer of a multi-hop, ad-hoc wireless network. We assume the physical layer supports a variable bit-rate. Most of the existing MACs analyze impacts of only o ...

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 ...

RFID Traceability: A Multilayer Problem

Gildas Avoine, Philippe Oechslin

RFID tags have very promising applications in many domains (retail, rental, surveillance, medicine to name a few). Unfortunately the use of these tags can have serious implications on the privacy of people carrying tagged items. Serious opposition from con ...

Improving TCP Performance in Ad Hoc Networks Using Signal Strength Based Link Management

Fabius Klemm

Mobility in ad hoc networks causes frequent link failures, which in turn causes packet losses. TCP attributes these packet losses to congestion. This incorrect inference results in frequent TCP re-transmission time-outs and therefore a degradation in TCP p ...

Media Aware Routing in Large Scale Networks with Overlay

Pascal Frossard, Dan Jurca, Sofija Petrovic

This paper presents a new routing strategy, that selects the best network paths in an overlay network, in order to minimize the distortion perceived by the end user. We first propose a model that reports the video distortion as a function of the encoding r ...

Optimal grade transition for polyethylene reactors via NCO tracking

Dominique Bonvin, Levente Bodizs

In fluidized-bed gas-phase polymerization reactors, several grades of polyethylene are produced in the same equipment by changing the operating conditions. Transitions between the different grades are rather slow and result in the production of a considera ...
