Reputation Systems for Self-Organized Networks

Jean-Yves Le Boudec, Jochen Mundinger, Sonja Buchegger

Self-organized networks such as mobile ad-hoc, Internet-based peer-to-peer, wireless mesh and Fourth Generation (4G) Wireless networks depend on cooperation of nodes. Reputation systems help nodes decide with whom to cooperate and which nodes to avoid. The ...

Effective Usage of Computational Trust Models in Rational Environments

Karl Aberer

Reputation-based trust models based on statistical learning have been intensively studied for large-scale distributed systems whereas practical application of game-theoretic approaches using sanctioning are still very little understood in such settings. Th ...

Revocation Games in Ephemeral Networks

Jean-Pierre Hubaux, Mark Felegyhazi, Maxime Raya

A frequently proposed solution to node misbehavior in mobile ad hoc networks is to use reputation systems. But in ephemeral networks - a new breed of mobile networks where contact times between nodes are short and neighbors change frequently - reputations ...

A Generic Mean Field Convergence Result for Systems of Interacting Objects

Jean-Yves Le Boudec, Jochen Mundinger

We consider a model for interacting objects, where the evolution of each object is given by a finite state Markov chain, whose transition matrix depends on the present and the past of the distribution of states of all objects. This is a general model of wi ...

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

Jean-Yves Le Boudec, Jochen Mundinger

The application of decentralized reputation systems is a promising approach to ensure cooperation and fairness, as well as to address random failures and malicious attacks in Mobile Ad-Hoc Networks. However, they are potentially vulnerable to liars. With o ...

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 ...
