Modal analysis is the process of estimating a system's modal parameters such as its natural frequencies and mode shapes.

One application of modal analysis is in structural health monitoring (SHM), where a network of sensors may be used to collect vibration data from a physical structure such as a building or bridge. There is a growing interest in developing automated techniques for SHM based on data collected in a wireless sensor network.

In this talk, I will describe various sampling and compression strategies that one might consider in a physical sensor network; these methods are intended to minimize power consumption by allowing the data to be sampled and/or transmitted more efficiently.
