摘 要:In this chapter, some results related to the interpretation and use of data in DPS diagnostics using sensor networks with mobile nodes were presented. Specifically, theoretical research was carried out and computationally efficient methods to determine optimal configurations of mobile sensor networks for contaminating source detection and estimation were developed. What is more, proper implementation and testing of the computer code for verification of the proposed approach were done based on simulations. The key assumption made here was that the paths of the moving sources were unknown, but they were sufficiently smooth to be approximated by combinations of given basis functions. Parametrization of the source trajectories made it possible to reduce the source detection and estimation problem to that of parameter identification. In order to estimate the source and medium parameters, the maximum-likelihood estimation was used.
