Defining a mobile architecture for structural health monitoring

The proliferation of powerful, programmable mobile devices along with the availability of wide-area connectivity has provided a powerful platform to sense and share location, motion, acoustic and visual data. The new generation of smart devices feature a variety of sensors that can be used towards building scalable and extendable monitoring systems with hundreds of nodes. In this paper, we report on work in progress to develop a distributed mobile system for Structural Health Monitoring utilizing smart handheld devices. We describe a distributed clustering algorithm that clusters nodes that produce similar power spectra and thus enables the implementation of decentralized heavy computation monitoring algorithms.
