Recognition of Multi-Event on the Single Sensor
Donghyok Suh, Juhye Yook · Advanced science and technology letters · 2014
Sensors perform various activities to detect in a recent environment of Internet of things and ubiquitous sensor network. A single sensor detects multi-events in some cases while multi-sensors detect a single event and report in some other cases. The study presented a way of data clustering to classify events detected by a single sensor in circumstances where information is ob- tained by a form of data stream. Data was grouped in three types of events when clustering was applied for sensor data detected and reported. The follow- ing results also showed that clustering distinguished the events in the conse- quent time timeslots. The clusters displayed changing patterns with time. This result would contribute to the study field of context inference based on data stream.
