Abstract: An event-triggered mechanism based on dual-criterion is designed to reduce the amount of data transfer between each detection unit and the data fusion center in a sensor network. The proposed event-triggered mechanism has been utilized to schedule the data transfer between each detection unit and the data fusion center. And a nonlinear fusion estimator based on the aforementioned event-triggered mechanism and the square-root cubature Kalman filter is proposed to obtain better estimation performance than those of existing event-triggered fusion estimation algorithms. The simulated results and experimental results show that the proposed event-triggered fusion estimator can reduce the data transfer amount compared with the fusion estimator based on periodic transmission mechanism and offer better estimation performance than those of existing event-triggered fusion estimators.
