The skyline query method in the wireless sensor network has been widely used in the field of environmental monitoring, the field is mostly related to the spatial distance. For the multidimension of space location, it brings enormous computational cost for the general skyline query method in terms of the property calculation. In order to improve the(More)
RFID holds the promise of real-time identifying, locating, tracking and monitoring physical objects without line of sight, and can be used for a wide range of pervasive computing applications. To achieve these goals, RFID data have to be collected, filtered, and transformed into semantic application data. RFID data, however, contain false readings and(More)
Smart Grid is an important application in Internet Of Things (IOT). Monitoring data in large-scale smart grid are massive, real-time and dynamic which collected by a lot of sensors, Intelligent Electronic Devices (IED) and etc.. All on account of that, traditional centralized storage proposals aren't applicable to data storage in large-scale smart grid.(More)
Operating data in smart grid are usually collected by a lot of sensors in Cyber-Physical systems. Monitoring data in large-scale smart grid are massive, real-time and dynamic. All on account of that, traditional centralized storage proposals isn't applicable to data storage in large-scale smart grid. Therefore, we propose a data-centric storage approach in(More)
In this paper, some concepts of real-time system (e.g., dealine, slack and criticalness) are introduced into some high-critical specific applications of Data Stream Management System (DSMS). In light of the features of continuous queries in DSMS, they are given new meaning. According to these concepts, a real-time scheduling strategy based on priority is(More)
