Automatic nonverbal analysis of social interaction in small groups: A review

Daniel Gatica-Perez

An increasing awareness of the scientific and technological value of the automatic understanding of faceto- face social interaction has motivated in the past few years a surge of interest in the devising of computational techniques for conversational analy ...

On the Specification of Partitionable Group Membership

André Schiper, Stefan Pleisch, Olivier Rütti

Group communication in partitionable systems has been the focus of many research activities over the last decade. Fault-tolerant applications in a partitionable system model generally rely on two basic services: a group membership service and a reliable mu ...

Impact of Vehicular Communications Security on Transportation Safety

Jean-Pierre Hubaux, Panagiotis Papadimitratos

Transportation safety, one of the main driving forces of the development of vehicular communication (VC) systems, relies on high-rate safety messaging (beaconing). At the same time, there is consensus among authorities, industry, and academia on the need t ...

A Predicate-Based Approach to Dynamic Protocol Update in Group Communication

André Schiper, Olivier Rütti

In this paper we study dynamic protocol updates (DPU), which consist in replacing, without interruption, a given protocol during execution. We focus especially on group communication protocols. The paper proposes a methodology to conveniently describe whic ...

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 ...

Evolutionary Conditions for the Emergence of Communication in Robots

Dario Floreano, Stéphane Magnenat, Laurent Keller, Sara Mitri

Information transfer plays a central role in the biology of most organisms, particularly social species [1, 2]. Although the neurophysiological processes by which signals are produced, conducted, perceived, and interpreted are well understood, the conditio ...

Broadcast, relay and feedback in Gaussian channels

Sibi Raj Bhaskaran Pillai

Network information theory explores the fundamental data transport limits over communication networks. Broadcasting and relaying are two natural models arising in communication contexts where multiple users share a common communication medium. Number of re ...

Advances in the Design and Implementation of Group Communication Middleware

André Schiper, Sergio Mena, Olivier Rütti, Rachele Fuzzati, Daniel Bünzli

Group communication is a programming abstraction that allows a distributed group of processes to provide a reliable service in spite of the possibility of failures within the group. The goal of the project was to improve the state of the art of group commu ...

Dependable Systems

André Schiper

Improving the dependability of computer systems is a critical and essential task. In this context, the paper surveys techniques that allow to achieve fault tolerance in distributed systems by replication. The main replication techniques are first explained ...

Efficient secure aggregation in VANETs

Jean-Pierre Hubaux, Maxime Raya, Adel Aziz

In VANETs, better communication efficiency can be achieved by sacrificing security and vice versa. But VANETs cannot get started without either of them. In this paper, we propose a set of mechanisms that can actually reconcile these two contradictory requi ...
