In open, technical, multi-agent based systems, self-interested agents can show behaviours that degrade the performance of the system. This can be countered by providing cooperation incentives. In this paper, we present a formalisation of delegation incentives for an open, agent-based, Desktop Grid system, based on decision trees. We then discuss reputation-based delegation strategies, as well as replication-based delegations strategies and focus on the incentives these strategies provide for agents to cooperate. We further show why we see room for improvement, and how this can be achieved with organisation-based delegation. We propose a delegation strategy based on
Trusted Communities
and present evaluation results for the comparison of these strategies with respect to the achieved average speedup in the system.
