Variable Window Operation Method to Respond to Context Reasoning
Donghyeok Seoh, Young-Hwan Oh · Advanced science and technology letters · 2015
This study proposes a method of determining a window size for data stream flexibly and variably. In the proposed method, a sliding window size is controlled variably depending on the evaluation of the event detected and reported by a sensor. Therefore, it is necessary to make criteria to judge rapid changes in sensing values and critical events, and to come up with a reasonable interoperability scheme in consideration of the lapse of time, and the development and declination of event context. This study tries to find a reasonable sliding window size control method interacting with context and thereby to contribute to the research on flexible and efficient context reasoning and context awareness.
