Designing and Implementation of Sensor Stream Processing System using the Dynamic Time Warping Distance

Abstract ,In recent years，stream processing technology which recognizes the object states with sensors gets great attention． For example，the system recognizes which the attached the sensor is walking or standing by using the wave pattern data from the acceleration sensor．The more the system，the more the application of the system increases． However，in the most sensor stream processing systems，the time to process the sensor data increases．Therefore，in this paper，we design and implement the sensor stream processing system using Dynamic Time Warping (DTW) distance．DTW is robust for changes in time，and the high recognizing performance．Therefore，it is possible to recognize many,states with high accuracy by applying to the
