Abstract: In this paper, we focus on the multi-acoustic source localization algorithm based on wireless sensor networks. First, the logarithm quantization strategy is proposed for the propagation characteristics of the ultrasonic source. The nodes calculate the quantized data according to the quantization strategy and the measured value, and transmit the quantized data to the base station. The base station then estimates the localization of the acoustic source with the proposed multi-acoustic source localization algorithm based on the likelihood C-means clustering algorithm. The effectiveness of the proposed algorithm under different parameters is verified and the simulation results show that the proposed algorithm can estimate the position of the multi-acoustic source more accurately and has some robustness to packet loss rate.
