Summary:An adaptive protocol that manages storage for base stations in mobile computing environments is presented. The protocol integrates leasing storage management with a time-based coordinated checkpointing mechanism. The leasing enables storage managers to control disk-space effectively. Leasing prevents hanged processes from indefinitely retaining storage, and in addition, garbage collection is simple. Time-based checkpointing is integrated with leasing to reduce the number of messages for establishing consistent global states. The checkpointing mechanism uses a 3-level storage hierarchy to improve checkpointing performance.
