Decentralized Monitoring with Mobile Sensor Networks

In this video, Dr. Yang Wang explains that by providing a high spatial resolution and reconfigurable architecture, autonomous mobile sensors can constitute an intelligent mobile sensor network for use in structural health monitoring. In collaboration with Prof. Kok-Meng Lee’s group at Georgia Tech, a magnet-wheeled mobile sensor prototype has been developed for navigating on ferromagnetic structures. Their research begins with investigating criteria and principles for designing mobile sensor nodes. Decentralized strategies are being developed to best utilize the high spatial resolution enabled by the mobile sensing data. Their aim is to discover substructure-based finite element model updating and system identification algorithms that enable decentralized synthesis of sensor data at unprecedented high spatial resolution.
