N2 - Emerging wireless technologies have the promise of improving the centralized cable-based Structural Health Monitoring (SHM) system performances. Recently, a smart sensor based on the Berkeley mote platform was introduced, and application to the next generation of SHM and control was proposed. In this study, the performance of the latest version of the "mote", called IRIS mote, is experimentally investigated through dynamic tests of an in-house cable-stayed bridge model. This paper focuses on the verification of wireless sensor network integration technologies and their application on determination of structural dynamic properties. Six IRIS wireless sensors were installed on the center and quarter span of the bridge model to measure acceleration signals. The dedicated sensor network platform includes the multi-functional wireless nodes, base station, data acquisition software, and computer is designed for experiment evaluation. The results of dynamical tests using the wireless monitoring system are compared with those using wired instrumentations. A finite element model was also developed to investigate the dynamical properties of the bridge model. The experiment results, combined with the FE analysis results, demonstrate the IRIS mote as a wireless smart sensor has sufficient performance for the intended purpose.
