Using Adaptive Agents for the Fault-Tolerant Mobile Computing System
This paper presents a fault-tolerance scheme based on mobile agents for the reliable mobile computing systems. The mobility of the agent is suitable to trace the mobile hosts in the system and the intelligence of the agent makes it efficient to support the fault-tolerance services. The proposed scheme especially focuses on the adaptiveness of the agent. The agents try to keep the failure-recovery cost and the failure-free operation cost within a certain level, regardless of the hand-off frequency of the mobile hosts. They also try to balance the two costs.
