Application of spatial-temporal correlation in data fusion for wireless sensor network

These spatial and temporal correlations along with the collaborative nature of the WSN bring significant potential advantages for the development of data fusion. This paper, briefly introduces the classification of data fusion, the main fusion method, and focused on the latest progress of application of temporal correlation, spatial correlation, and spatial-temporal correlation in data fusion, respectively. At the same time, we also presented some shortcoming of these solutions and the direction of improvement.
