Atomic broadcast

Nils Richard Ekwall

Within only a couple of generations, the so-called digital revolution has taken the world by storm: today, almost all human beings interact, directly or indirectly, at some point in their life, with a computer system. Computers are present on our desks, co ...

Slowing light in optical fibres sees fast progress

Luc Thévenaz

Slowing down light to produce optical delay lines for communication networks has advanced enormously in the last year. Luc Thévenaz and Miguel Gonzalez-Herraez chart this recent progress and describe the new challenges facing developers of practical device ...

Reputation in Self-Organized Communication Systems and Beyond (Invited Paper)

Jean-Yves Le Boudec, Jochen Mundinger

Efficiently handling reputation is important in dealing with free-riding, malicious attacks and random failures in self-organized communication systems. At the same time, work in this context is often found to be relevant in many other disciplines, in part ...

Efficient Distributed Multiresolution Processing for Data Gathering in Sensor Networks

Razvan Cristescu, Jugoslava Acimovic

We consider large sensor networks where the cost of collecting data from the network nodes to the data gathering sink is critical.~We propose several algorithms that use limited local communication and distributed signal processing to make communication mo ...

Architectural Issues of JMS Compliant Group Communication

Nils Richard Ekwall, Arnas Kupsys

Group communication provides one-to-many communication primitives that simplify the development of highly available services. Despite advances in research and numerous prototypes, group communication stays confined to small niches. To facilitate the accept ...

Adaptive Distributed Algorithms for Power-Efficient Data Gathering in Sensor Networks

Razvan Cristescu, Jugoslava Acimovic

In this work, we consider the problem of designing adaptive distributed processing algorithms in large sensor networks that are efficient in terms of minimizing the total power spent for gathering the spatially correlated data from the sensor nodes to a si ...

A lower bound to the scaling behavior of sensor networks

Martin Vetterli, Michael Christoph Gastpar

For a class of sensor networks, the task is to monitor an underlying physical phenomenon over space and time through a noisy observation process. The sensors can communicate back to a data collector over a noisy channel. The key parameters in such a se ...

On the role of feedback in large sensor networks

Michael Christoph Gastpar

Feedback can considerably simplify the task of approaching and achieving the performance limits predicted by information theory. This paper determines some of the potential offered by feedback in a typical sensor network situation that could be termed moni ...

Towards Flexible Finite-State Machine Based Protocol Composition

André Schiper, Sergio Mena, Nils Richard Ekwall, Stefan Pleisch

Group communication provides primitives that ensure reliable and ordered delivery of messages to a group of destinations. It is an important building block for replicated fault-tolerant applications such as replicated databases. In the past, most group com ...

The VidTIMIT Database

This communication describes the multi-modal VidTIMIT database, which can be useful for research involving mono- or multi-modal speech recognition or person authentication. It is comprised of video and corresponding audio recordings of 43 volunteers, recit ...
