Abstract
This invention relates to the Internet of Things (IOT), and discloses a method and apparatus of data filtering in the IOT, where the IOT includes a plurality of sensor devices. The method includes: inputting an application deployed rule; converting the rule into at least one sub-predicate expression having static predicates and dynamic predicates; inputting data collected by the sensor devices; matching the collected data with the static predicates and the dynamic predicates of the sub-predicate expression in sequence; and distributing matched data to the application. In this invention, a rule is divided into static and dynamic predicates, and a match is performed on static predicates before dynamic predicates, so that the speed of predicate match can be improved and fast and efficient data filtering in the IOT can be achieved.
