Abstract: Data fusion in wireless sensor networks is one of the key Technologies. In this paper, for the problem of large deviation of data fusion based on weighted fuzzy logic algorithm in wireless sensor networks, a new method is proposed. First to eliminate the flawed data through analysis of initial data using the idea of k-mean clustering, and to revise the weighting factors of weighted fuzzy logic algorithm with the rest authentic data, and then integrate all data by means of weighted method to get the final fusion result. Experimental results show that this method can achieve higher integration accuracy compared with the other same fusion methods.

 

Keywords: Data fusion, Fuzzy logic algorithm, Wireless sensor networks, K-mean clustering, Weighting factors.
