Abstract :
Data fusion is one of the key technologies of wireless sensor network. This paper designed the fusion process of the WSN measured data. In order to exclude outliers, the measured values of sensor nodes in each group are tested for consistency firstly, and then the batch estimation algorithm is used to estimate the measurement values, at last, according to the value of each sensor measurement variance, an adaptive weighted calculation method was designed to get the final fusion values of the environmental factors. The proposed data fusion method greatly enhanced the WSN communication efficiency, improved the measurement precision and decreased the energy consumption of the wireless sensor node.
