3D Imaging based on Single Photon Detectors

Edoardo Charbon, Cristiano Niclass

This paper introduces a mathematical model to evaluate fast and cost-effective 3D image sensors based on single photon detectors. The model will help engineers evaluate design parameters based on operating conditions and system performance. Ranging is base ...

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 ...

The Complex Facets of Reputation and Trust

Karl Aberer, Wojciech Galuba, Zoran Despotovic

Trust and reputation systems have proven to be essential to enforcing cooperative behavior in peer-to-peer networks. We briefly describe the current approaches to building reputation systems: social networks formation, probabilistic estimation and game the ...

Analysis of a Robust Reputation System for Self-Organized Networks

Jean-Yves Le Boudec, Jochen Mundinger

Self-organized networks require some mechanism to ensure cooperation and fairness. A promising approach is the use of decentralized reputation systems. However, their vulnerability to liars has not yet been analyzed in detail. In this paper, we provide a r ...

Analysis of a Reputation System for Mobile Ad-Hoc Networks with Liars

Jean-Yves Le Boudec, Jochen Mundinger

Using decentralized reputation systems is a promising approach to ensuring cooperation and fairness in Mobile Ad-Hoc Networks. However, they are vulnerable to liars and robustness has not been analyzed in detail. With our work, we provide a first step to t ...

Eliminating Undesired Equilibrium Points from Incentive Compatible Reputation Mechanisms

Boi Faltings, Radu Jurca

Choosing the best out of an increasing number of options requires reliable and accurate information. As our time and resources are limited, we commonly use the experience of others in order to take decisions. Reputation mechanisms aggregate in a formal way ...

A Robust Reputation System for Peer-to-Peer and Mobile Ad-hoc Networks

Jean-Yves Le Boudec, Sonja Buchegger

Reputation systems can be tricked by the spread of false reputation ratings, be it false accusations or false praise. Simple solutions such as exclusively relying on one`s own direct observations have drawbacks, as they do not make use of all the informati ...

Coping with misbehavior in mobile ad-hoc networks

Sonja Buchegger

In this work, we address the question of how to enable a system to operate despite the presence of misbehavior. Specifically, in a mobile ad-hoc network, how can we keep the network functional for normal nodes when other nodes do not route and forward corr ...

Analysis of a Robust Reputation System for Self-Organized Networks

Jean-Yves Le Boudec

Self-organized networks require some mechanism to ensure cooperation and fairness in the face of individual utility maximizing users and potential malicious attacks. Otherwise, network performance can be seriously deteriorated. One promising approach are d ...
