Checkpoints capture/rollback recovery, mobile computing, Java Virtual Machine.


This paper presents a checkpoints mechanism for mobile Java applications. This mechanism takes local checkpoints. It is integrated directly in our own embedded Java Virtual Machine named Scratchy. We propose a global and an in cremental method which are evaluated and compared each other. Evaluation is done with a benchmark and two applica tions. It shows that the incremental method yields shorter capture times than the global one. It also shows that the mechanism is transparent from the user standpoint and has a low overhead on the applications.
