| Popis: | This article focuses on a proposal of the strategy for deploying a set of mobile sensors in the network dedicated to an inverse problem of the physical phenomena which can be described by the partial differential equation system. The proposed method is developed by using the norm L2, of the sensitivity induced by the variation of the parameters to be identified. An algorithms of choice of the best sensor locations among the candidate sensors whose positions are imaginary will be presented in offline and online modes. This makes it possible to reduce the spatial region of observation to a relevant dimension and the computational time of the proposed unknown parameter identification method. This approach offers the opportunity to move mobile sensors in order to increase the overall sensitivity and thus to improve the quality of the identification which is a shorter delay and better accuracy. |
