An Extended Kalman Filter-Based Data Fusion Method for Wireless Sensor Networks
Abstract
For the requirement of physiological signal monitoring in the prevention of disease and in early diagnosis, the wireless sensor network plays an important role both for the physiological signal collection and the communication between the user and the remote medical service station. However, most of its energy is wasted during the transmission which shortens the network lifetime. This chapter focuses on the data fusion method with an extended Kalman filter by saving the waste of energy at the source. The expected result is to reduce the waste of energy during the transmission and lengthen the network lifetime. The simulation experiment demonstrates that the proposed method obtains the satisfactory result. It should have a good practical value in the application of physiological signal monitoring embedded in intelligent garment.
