Moving horizon state estimation for wireless sensor networks

The state estimation based on quantized measurements of wireless sensor networks is studied using the moving horizon estimation methodology. The current moving horizon strategies can not deal with quantized measurements since they use the whole information of measurements. In this work we assume that the sensors are send only one bit data to the fusion center at each time slot. Compared with other estimation approaches for wireless sensor networks, the moving horizon method proposed in this paper can reduce the computation complexity and still provides satisfactory estimation quality. Finally a numerical example is given to demonstrate our algorithms.
