Mobile Target Tracking Based on WSN and Calibration of Environment Parameter

A method of mobile target tracking based on RSSI for wireless sensor networks application is adopted. This method realized target tracking by mobile target emitting radio in wireless sensing field periodically and EKF is used to get better target tracking accuracy. It is low cost of hardware. At the same time, research is done on calibrating of environment parameter and least square is used to extract the environment parameter. Finally, an experiment is conducted to validate the value of this mobile target tracking method.
