The Weighted Center Localization (WCL), which is a classical localization scheme for the Wireless Sensor Network (WSN), can't decrease the average localization errors and the maximum errors simultaneously due to the fixed weight argument. Improving the localization accuracy of WCL is to decrease the distance measurement errors or to set a proper dynamic weight argument. We have already improved the...
With the arrival of population aging society, the health care of the elderly becomes more important. The fall detection algorithm is the core of the fall detection alarm system, so it is the key for the research and development of the fall detection system to analyze and select the appropriate algorithm for the detection of falling. It is one of the most important indicators of elder health monitor...
In this paper, a novel method based on a B-spline approximation and the extended Kalman filter (EKF) is proposed for the signal reconstruction of nonlinear multifunctional sensors. The B-spline approximation is a very effective and conventional tool for nonlinear modeling. However, the computation of the B-spline control array by the least square method is very complex for implementation on microprocessors...
