Fault tolerance is fundamental to the further development of mobile agent applications. It ensures that the agent arrives at its destination and thus prevents a partial or complete loss of the agent. This paper surveys the current approaches to fault-tolerant mobile agent execution. Most of these approaches are based on replication. We propose a classification into temporal-replication-based and spatial-replication-based approaches and discuss the advantages and disadvantages of these approaches.
