People treated under the U-Health system are potential patients, and their condition is generally not critical, so most of their vital sign data are normal. Therefore, it is more efficient if the sensors attached to them send only abnormal data selectively without sending all data. In this paper, we propose an arrhythmia detection method in which ECG(More)
In USN systems, data streams are generated from sensor nodes. It is very important to find information from these data stream because data streams present practical phenomena. Data streams have temporal properties, so we can apply sequential pattern mining methods to data streams. However, because data streams are continuous and infinite, we need to develop(More)
