Using Adaptive Agents for the Fault-Tolerant Mobile Computing System
[chapter]
2006
Lecture Notes in Computer Science
Preserved Fulltext
The agents try to keep the failure-recovery cost and the failure-free operation cost within a certain level, regardless of the handoff frequency of the mobile hosts. ...
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 others are mobile agents, called the checkpointing agent (CPA) and the log agent (LGA), each of which manages and makes the migration decision of the latest checkpoint and the message logs, respectively ...

In this paper, we present an efficient failure recovery scheme for mobile applications based on movement-based checkpointing and logging. ...
We identify the optimal movement threshold which will minimize the recovery cost per failure as a function of the mobile node's mobility rate, failure rate and log arrival rate. ...
Thus, there exists a tradeoff between recovery time and the total time spent on the checkpoints and logging for a fixed cost. ...
