| Shrnutí: | This paper presents an efficient recovery scheme based on checkpointing and message logging for mobile computing systems. For the efficient management of checkpoints and message logs, a movement-based scheme is proposed. Mobile hosts carrying their recovery information to the nearby mobile support station can recover instantly in case of a failure, however, the cost to transfer the recovery information must be high. On the other hand, the recovery information remaining dispersed over a number of support stations visited by mobile hosts must incur very high recovery cost. To balance the failure-free operation cost and the recovery cost, in the proposed scheme, the recovery information of a mobile host remains at the visited support stations while the host moves within a certain range. Only when the host moves out of the range, the recovery information is transferred to a nearby mobile support station. As a result, the proposed scheme can control the information transfer cost as well as the recovery cost. |
