Network Coding Applications

Christina Fragouli, Emina Soljanin

Network coding is an elegant and novel technique introduced at the turn of the millennium to improve network throughput and performance. It is expected to be a critical technology for networks of the future. This tutorial deals with wireless and content di ...

Teaching Enterprise and Service-Oriented Architecture in Practice

Gil Regev, Alain Wegmann, Lam Son Lê, Irina Rychkova, José Diego de la Cruz Garcia

Many companies expect their IT developers to understand their business strategy and to specify IT systems that will impact favorably the execution of their business strategy. Enterprise Architecture (EA) and Service-Oriented Architecture (SOA) address thes ...

Mirroring Resources or Mapping Requests: Implementing WS-RF for Grid Workflows

Thomas Heinis

The Web services resource framework (WS-RF) and the Web services notification (WS-N) specifications are a crucial component of grid infrastructures. They provide a standardized interface to stateful services so that they can be managed remotely. There are ...

SoS: self-organizing substrates

Anwitaman Datta

Large-scale networked systems often, both by design or chance exhibit self-organizing properties. Understanding self-organization using tools from cybernetics, particularly modeling them as Markov processes is a first step towards a formal framework which ...

Semantic Segmentation of Radio Programs Using Social Network Analysis and Duration Distribution Modeling

Sarah Favre, Alessandro Vinciarelli

This work presents and compare two approaches for the semantic segmentation of broadcast news: the first is based on Social Network Analysis, the second is based on Poisson Stochastic Processes. Preliminary experiments address the problem of segmenting aut ...

Solving Atomic Broadcast with Indirect Consensus

André Schiper, Nils Richard Ekwall

In previous work, it has been shown how to solve atomic broadcast by reduction to consensus on messages. While this solution is theoretically correct, it has its limitations in practice, since executing consensus on large messages can quickly saturate the ...

The Effect of Mobility on Cooperation in Ad Hoc Networks

Jean-Pierre Hubaux, Mark Felegyhazi, Levente Buttyan

Ad hoc networks are expected to be used in many different situations. A common characteristic among these situations is that the nodes have to cooperate with each other. This problem is particularly crucial, if each node is its own authority. Reckoning the ...

Heterogeneous coupling by virtual control methods

Alfio Quarteroni

tual control method, recently introduced to approximate elliptic and parabolic problems by overlapping domain decompositions, is proposed here for heterogeneous problems. Precisely, we address the coupling of an advection equation with a diffusion-advectio ...
