GROUP CHECKPOINTING SCHEME FOR PARTITION FAILURE RECOVERY IN MOBILE DATABASE-SYSTEMS - GCS MD/

In the forthcoming mobile computing environments, especially in a mobi le database systems, changes should be made to the technologies used i n traditional distributed systems. This is because the mobility induce s the change of basic assumption imposed by the traditional distribute d systems. Checkpointing scheme, as a recovery scheme in a distributed database systems is also subject to be changed to accommodate mobile environments. We propose a group checkpointing scheme, which enhances traditional distributed checkpointing scheme for mobile databases.
