Malicious Workers Tolerance in an Agent-Based Grid Resource Brokering System - Preliminary Considerations (Short Paper)

The Agent in Grid (AiG) project develops an agent-based infrastructure for resource management in the Grid. The basic assumptions of the project are that (1) agents work in teams, and (2) information is ontologically represented and semantically processed. Thus far, issues involved in trust management were considered only from the point of view of fulfillment of contracts between stakeholders. However, it is also possible that some workers that fulfill their contracts, return incorrect results. In this note, we consider how the trust management in the AiG project can be further conceptualized by using a reputation-based voting.
