| Abstract: | A design scheme of multi-target real-time tracking system is presented and factors affecting tracking performance are analyzed.A kind of Extended Kalman Filter(EKF) algorithm based on single observation and self-adaptive node scheduling scheme based on the function of the EKF algorithm is proposed. In addition, many mechanisms and strategies are introduced as auxiliary for trajectory tracking. The experimental result validates the good performance of the tracking algorithm and node scheduling strategy. It has advantages of reducing calculation and energy consumption, shortening measurement period and improving tracking precision. |
| Keywords: | wireless sensor network target tracking self-adaptive node scheduling EKF |
