Evaluation and Checkpointing of Fault Tolerant Mobile Agents Execution 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 paper, we present evaluation of the performance 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 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. The use of mobile agent, however, is critical and requires reliability in regard to mobile agent failures that may lead to bad response time and hence the availability of the system may lost. In this study, a fault tolerance technology is proposed in order that the system autonomously detects and recovers the fault of the mobile agent due to a failure in a transmission link. Also discuss how transactional agent with types of commitment constraints can commit. Furthermore this paper proposes a solution for effective agent deployment using dynamic agent domains.
