A fault-tolerant protocol for mobile agent

Abstract

Mobile agent technology has been proposed for a variety of applications. Fault-tolerance is fundamental to the further development of mobile agent applications. Fault-tolerance prevents a partial or complete loss of the agent. Simple approaches such as checkpointing are prone to blocking, replications scheme is expensive since it has to maintain multiple replicas. In this paper, a new approach rooted from checkpointing is proposed. This scheme can guarantee to detect and recover most failure scenarios in mobile agent systems, even if there occurs machine failure. © Springer-Verlag Berlin Heidelberg 2004.
