This work presents a data-centric strategy to meet deadlines in soft real-time applications in wireless sensor networks. 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(More)
This work proposes the use of Information Theory for the characterization of vehicles behavior through their velocities. Three public data sets were used: i. Mobile Century data set collected on Highway I-880, near Union City, California; ii. Borlänge GPS data set collected in the Swedish city of Borlänge; and iii. Beijing taxicabs data set collected in(More)
Wireless sensor networks are an important technology for making distributed autonomous measures in hostile or inaccessible environments. Among the challenges they pose, the way data travel among them is a relevant issue since their structure is quite dynamic. The operational topology of such devices can often be described by complex networks. In this work,(More)
—This work presents a general methodology to perform sensor stream reduction in wireless sensor networks. This methodology considers the application requirements, the reduction design, and the data reduce validation. Specifically, the reduction design, we present a architecture that can be applied to reduce the data when it is sensed or routed through to(More)
