Optimistic Replication Approach for Transactional Mobile Agent Fault Tolerance
(CERIST, 2010-04) Zeghache, Linda; Badache, Nadjib
The mobile agent is a computer program that can move agent and deal with semantic failures to ensure atomic execution and transactional support for mobile agent between different hosts in heterogeneous networks. This paradigm is advantageous for distributed systems implementation, especially in mobile computing application characterized by low bandwidth, high latency and unreliable networks connections. Mobile agent is also attractive for distributed transactions applications. Although mobile agent has been studied for twenty years for some good reasons, it is not largely used in developing distributed systems for simple reasons: important issues like security and fault tolerance are not solved in effective way. In this paper we address the issue of fault tolerance in mobile agent systems and transactional support. We present the agent system design and describe the protocol of our approach in which we treat infrastructure failures to prevent a partial or complete loss of mobile
Providing Reliability for Transactional Mobile Agents
(Springer Berlin Heidelberg, 2013) Zeghache, Linda; Hurfin, Michel; Moise, Izabela; Badache, Nadjib
A transactional agent is a mobile agent that migrates from a site to another one in order to execute a distributed transaction assigned by a user. Works on transactional mobile agents have identified two problems that can not be solved by the agent alone. The first one is related to the reliability. The lack of a fault tolerant infrastructure and methodologies that address fault tolerant execution of mobile agents highlights a major drawback of this technology. The second problem for which the agent needs assistance is related to the atomic validation of the transaction. In this paper we address the mobile agent fault tolerance and the transactional support.

A transactional agent is a mobile agent which migrates from a site to another site to execute a distributed transaction assigned by a user. Works on transactional mobile agents have identified two problems that can’t be solved by the agent alone. The first one is related to the reliability. The lack of a fault tolerant infrastructure and methodologies that address fault tolerant execution of mobile agents highlights a major drawback of this technology. The second problem for which the agent needs assistance is related to the atomic validation of the transaction. In this paper we address mobile agent fault tolerance and a transactional support.
