Abstract
Traditional checkpoint intervals typically cannot control maximum recovery time for log-based checkpointing protocols and may cause unnecessary checkpointing overhead. In this thesis, an adaptive checkpointing protocol is designed to accurately enforce the user-defined recovery time and to reduce excessive checkpoints. Instead of using fixed checkpoint intervals, the adaptive protocol creates checkpoints based on the status of current execution. A receiver-based message logging algorithm has been implemented and evaluated on both wired and wireless networks. The experimental results show that the adaptive protocol incurs low overhead, avoids unnecessary checkpointing, and reduces failure-free execution time.
