摘 要：In this dissertation, the principle and value of data fusion are studied, and the existent typical touting protocol for Wireless Sensor Network (WSN). A kind of wireless sensor network data fusion algorithm based on the routing protocol LEACH is proposed, which is combines LEACH agreement with the hierarchical structure of the adaptive weighting combination. The hierarchy structure of each cluster design for an adaptive weighted model, through the adaptive weighted method from the sensor node of raw data acquisition to extract characteristic data, then will feature the data sent to converge node. We show by simulation that the algorithm has good data fusion efficiency, especially suitable for periodic report types of wireless sensor network.
