The k-set-agreement problem consists for a set of n processes to agree on less than k among n possibly different Values, each initially known to only one process. The problem is at the heart of distributed computing and generalizes the celebrated consensus ...
The main goal in network information theory is to identify fundamental limits of communication over networks, and design solutions which perform close to such limits. After several decades of effort, many important problems still do not have a characteriza ...
Former PhD students, post-docs and junior researchers of the Section de chimie et biochimie now holding positions at different universities and private companies remember the time they spent in Geneva and give an account of how this has set off and influen ...
The implementation of an image-based sensor device able to track people in an indoor environment is presented. The primary objective of this paper is to prove the feasibility of a sensor capable of sub-metre level tracking accuracy and costing approximatel ...

New entrants in postal markets usually set up delivery networks by concentrating on urban areas and large business customers. This implies that they operate their network highly centralized - at least in early phases of entrance. ...
We consider the problem of distributed estimation, where a set of nodes are required to collectively estimate some parameter of interest. We motivate and propose new versions of the diffusion LMS algorithm, including a version that outperforms previous sol ...
The aim of information-theoretic secrecy is to ensure that an eavesdropper who listens to the wireless transmission of a message can only collect an arbitrarily small number of information bits about this message. In contrast to cryptography, there are no ...
We apply a Design of Experiments method on the electrical potential equation of SOFC button cells in order to investigate how measurements may be improved regarding the parameter estimation of our model. With the use of a genetic algorithm we optimise the ...
In this paper we consider communication from a source to a destination over a wireless network with the help of a set of authenticated relays. We focus on a special ``diamond'' network, where there is no direct link between the source and the destination; ...
We consider the following communication problem over a directed graph. A source node wants to transmit a common message to a set of receiver nodes along with a private message to each of the receivers. We show a class of networks for which the achievable r ...
