The Interactive Cooperation Tournament
Distributed reputation systems are a self-organizing means of supporting trusting decisions. In general, the robustness of distributed reputation systems to misbehavior is evaluated by the means of computer based simulation. However, the fundamental issue arises of how to anticipate kinds of successful misbehavior. Existing work in this field approaches this issue in an ad-hoc manner. Therefore, in this paper, we propose a methodology that is based on interactive simulation with human subjects. The requirements for such interaction are discussed. We show how they are met by the Interactive Cooperation Tournament, a simulation environment for identifying promising counter-strategies to the distributed reputation system EviDirs which is showcased in our demo.
