Executive Summary

The reliable execution of a mobile agent is a very important design issue to build a mobile agent system and many fault-tolerant schemes have been proposed. Hence, in this paper, the authors present evaluation of the performance of the fault-tolerant schemes for the mobile agent environment. Their evaluation focuses on the checkpointing schemes and deals with the cooperating agents. They derive the FANTOMAS (FAult-ToleraNt apprOach for Mobile AgentS) design which offers a user transparent fault tolerance that can be activated on request, according to the needs of the task. A theoretical analysis examines the advantages and drawbacks of Fault-Tolerant approach for Mobile Agents.
