Abstract:
The Trusted Desktop Grid (TDG) is a self-organised, agent-based organisation, where agents perform computational
tasks for others to increase their performance. In order to establish a fair distribution and provide
counter-measures against egoistic or malicious elements, technical trust is used. A fully self-organised approach
can run into disturbed states such as a trust breakdown of the system that lead to unsatisfying system
performance although the majority of participants is still behaving well. We previously introduced an
additional system-wide control loop to detect and alleviate disturbed situations. Therefore, we describe an
Observer/Controller loop at system level that monitors the system status and intervenes if necessary. This
paper focuses on the controller part which instantiates norms as reaction to observed suspicious situations. We
demonstrate the benefit of our approach within a Repast-based simulation of the TDG. Therein, the impact of
disturbances on the
system performance is decreased significantly and the time to recover is shortened.
