Checkpointing and restarting techniques are familiar ways to realize the reliable distributed mobile computation. In this paper, we propose a hybrid checkpointing protocol where the mobile Host (MH) asynchronously takes checkpointing protocol while the Mobile support stations (MSS) synchronously takes checkpoints. We have also shown that the hybrid checkpoint protocol implies the less total processing time than the synchronous checkpointing.
