Abstract
Structural Health Monitoring (SHM) system is a promising technology to determine the health condition of a structure and localize its damage. In this paper, data backup mechanism for SHM system is proposed. Proposed mechanism shares data within sensor nodes. For conducting backup, there are three functions in the mechanism; node detection, backup node selection and backup data transfer function. Operation check and performance evaluation of the mechanism were conducted. Result of the operation check showed that backup within sensor nodes was conducted based on proposed mechanism. Additionally, result of the performance evaluation showed that backup by the proposed mechanism was conducted before a target structure collapses or great damage occurs.
