N2 - This is a concept paper developing the hybrid sensor network concept using a combinatorial approach of physical and virtual/model sensor arrays for acoustic source localization in solid media. This paper outlines the hybrid sensor network concept, virtual sensing system, and the associated sensor architecture. It elaborates on the physical sensor review, sensor characterization and evaluation process for damage and load sensors and the corresponding vendors. The model sensor grid concept is developed using predictive reduced order models for baseline and then updated using feedback loops from load and damage physical sensors. Some of the ongoing research on sensor placement strategies including binary sensing has been illustrated. The sensor placement strategies involve a combinatorial approach involving physical damage and load sensors to be strategically placed on a virtual sensor grid network.
