Studies on the Data Fusion within Wireless Sensor Network (WSN) Based on Adaptive Weighting Algorithm

摘要

Data fusion technology serves as one of the key techniques in WSN. In this paper, a novel data fusion algorithm based on the adaptive weighting algorithm was proposed. It can be used to calculate respective weighting coefficients with data measured by sensors without prior knowledge of sensor nodes and can timely regulate the influence of each sensor on final data fusion. According to the experiment and test, the accuracy and' fault tolerance of the proposed algorithm had been validated by Matlab simulation.
