A Method to Aggregate Fuzzy Sensor Data

Fuzzy sensor provides flexible ability to deal with symbolic information. The problem of the efficient aggregation of fuzzy sensor output information is a crucial point in multisensor based systems. This paper presented a novel method to aggregate fuzzy sensor data based on data association. First, a similarity measure is introduced to determine the agreement degree of each sensor. The importance of each fuzzy sensor, the relative agreement degree and the compound effect of the importance of fuzzy sensor are considered in this method. Then, a consensus degree coefficient is defined as a comprehensive measure for evaluating the relative worthiness of each fuzzy sensor's outputs. Based on the consensus degree coefficient, an aggregation method is proposed to fuse the fuzzy sensor data. Finally, an object recognition task is simulated to test the method. The results show the efficiency of this approach.
