Abstract: Mobile agents have attracted considerable interest in recent years . In the context of mobile agents , fault tolerance is crucial to enable the integration of mobile agent technology into today,s business applications. To further develop mobile agent technology, reliability mechanisms such as fault tolerance and transaction support are required. For this purpose, we first identify two basic requirements for fault-tolerant mobile agent execution: (1) non-blocking and (2) exactly-once. In this paper, we propose a fault-tolerant model for mobile agents executing in large distributed networks and analyze the life expectancy of mobile agents in our model. The key idea is the use of stochastic regularities of mobile agent's behavior-all the mobile agents in the network as a whole can be stochastically characterized though a single mobile agent may act randomly.Our analytical results reveal new theoretical insights into the statistical behaviors of mobile agents and provi!
de useful tools for effectively managing mobile agents in large networks.
