Evaluation of Fault Tolerant Mobile Agents in Distributed Systems

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 article, we present an evaluation of the per formance of the fault-tolerant schemes for the mobile agent environment. Our evaluation focuses on the checkpointing schemes and deals with the cooperating agents. We derive the Fault-Tolerant approach for Mobile Agents (FANTOMAS) design which offers a user transparent fault tol erance that can be activated on request, according to the needs of the task. We also discuss how a transactional agent with different types of commitment constraints can commit. Furthermore, this article proposes a solution for effective agent deployment using dynamic agent domains.
