The operation of wireless structural health monitoring systems is hindered by the limited power autonomy of wireless sensor nodes and the limited reliability of wireless communication. As a result, traditional structural health monitoring (SHM) practices dictating the centralized collection and processing of structural response data may be impractical for long-term wireless SHM systems. Alternatively, the inherent processing capabilities of wireless sensor nodes have enabled models used in SHM to be partially or fully embedded into the processing units of wireless sensor nodes. A major challenge in embedding models into wireless sensor nodes is to ensure that the merits of embedding the models undeniably outweigh the centralized collection of structural response data. To this end, the quality of embedded models, which essentially constitute software modules implementing mathematical models, needs to be tested with respect to performance. Quality management practices define quality of products, information or services, as “fitness for purpose”, which is assured by performing verification and validation (V&V) of the products, information, or services. Accordingly, this paper proposes a V&V framework for embedded models in wireless SHM systems. The embedded model V&V framework draws both from model verification and validation and from software verification and validation practices.
