This strategy considers three main aspects: (i) The design of real-time application to obtain the minimum deadlines; (ii) An analytic model to estimate the ideal sample size used by data-reduction algorithms; and (iii) Two data-centric stream-based sampling algorithms to perform data reduction whenever necessary. Simulation results show that our data-centric strategies meet deadlines without loosing data representativeness.en-USSensor-stream reduction algorithmsWireless sensor networkData-centric routing algorithmData centric sensor stream reduction for real-time applications in wireless sensor networksArtigo publicado em periodicoOs trabalhos publicados na Sensors podem ser reutilizados sem obtenção de permissão desde que a correta referência da publicação original seja dada.
