Abstract. To achieve an efficient utilization of cluster systems, a proper programming and operating environment is required. In this context, mobile agents are of growing interest as base for distributed and parallel applications. As mobile and autonomous software units, mobile agents can execute tasks given to the system and allocate independently all the needed resources. However, with growing cluster sizes, the probability of a failure of one or more system components and therewith the loss of mobile agents rises. While fault tolerance issues for applications based on "traditional" processes have been extensively studied, current agent environments provide only insufficient, if at all, extensions for a capable reaction on such kinds of failures. We examine fault tolerance with regard to properties and requirements of mobile agents, and find that independent checkpointing with receiver based message logging is appropriate in this context. 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 FANTOMAS.

“…The advantage that agent technology provides in this type of environment is the flexibility and redundancy of the communication paths among agents and the ability for agents to change location. Vogler et al 28 propose a distributed transaction model using a two-phase commit protocol to verify that an agent message has been delivered. This very well known approach can provide a means of ensuring that an agent transaction has successfully or unsuccessfully completed.…”

Over the past years, mobile agent technology has attracted considerable attention, and a significant body of literature has been published. To further develop mobile agent technology, reliability mechanisms such as fault tolerance and transaction support are required. This article aims at structuring the field of fault-tolerant and transactional mobile agent execution and thus at guiding the reader to understand the basic strengths and weaknesses of existing approaches. It starts with a discussion on providing fault tolerance in a system in which processes simply fail. For this purpose, we first identify two basic requirements for faulttolerant mobile agent execution: (1) non-blocking (i.e., a single failure does not prevent progress of the mobile agent execution) and (2) exactly-once (i.e., multiple executions of the agent are prevented). This leads us to introduce the notion of a local transaction as the basic building block for fault-tolerant mobile agent execution and to classify existing approaches according to when and by whom the local transactions are committed. In a second part, we show that transactional mobile agent execution additionally ensures execution atomicity and present a survey of existing approaches. In the last part of the survey, we extend the notion of fault tolerance to arbitrary Byzantine failures and security-related issues of the mobile agent execution.
