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 ...

Self-Policing Mobile Ad-Hoc Networks by Reputation

Jean-Yves Le Boudec, Sonja Buchegger

Node misbehavior due to selfish or malicious reasons or faulty nodes can significantly degrade the performance of mobile ad-hoc networks. To cope with misbehavior in such self-organized networks, nodes need to be able to automatically adapt their strategy ...

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 ...

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 ...
