Survey of Data Fusion in Wireless Sensor Network

Data fusion was to minimize the number of transmissions of sensor nodes,and the overall power consumption in the network.It made use of Kalman filter for target state estimation and applied data fusion of batch estimate to wireless sensor network for this problem.The method was to integrate the data of multi-sensors which were watching one object to improve the precision and the feasibility of the data.This method has been proved with great quantities of simulated data,and the multi-sensor multi-target data fusion arithmetic was proposed which integrated the data of multi-sensors which were watching different objects on this basis.
