Lightweight Message Logging Protocol for Distributed Sensor Networks
نویسنده
چکیده
Among a lot of rollback-recovery protocols developed for providing fault-tolerance for long-running distributed applications, sender-based message logging with checkpointing is one of the most lightweight fault-tolerance techniques to be capable of being applied in this field, significantly decreasing high failure-free overhead of synchronous logging by using message sender's volatile memory as storage for logging its corresponding message. However, attempting to apply this technique into large-scale and geographically distributed systems such as broker-based sensor networks, etc., the following problems should be addressed; reducing the number of control and data messages passing on core networks occurring during its fully message logging and recovery procedures. In this paper, we present a lightweight message logging protocol for distributed sensor networks to solve all of them by employing the current and future distributed systems' architectural features mentioned above.

متن کاملPractical Schemes using Logs for Lightweight Recoverable DSM
In the existing Fault-Tolerant Software Distributed Shared Memory (FT-SDSM) with the message logging, the logs are used only to recover the failed nodes. In our previous work, we have implemented a lightweight logging protocol, called remote logging, on the SDSM for fault tolerance, which incurs low logging overhead with a fast network and a remote memory for back-up data. In this paper, we pro...
