Each sensor node in wireless sensor network (WSN) uses only a single microphone instead of microphone arrays as its sensing device, which can guarantee the most important characteristics of WSN, such as small size, low power consumption and convenient deployment. In this paper, weighted linear least squares method (WLLS) was proposed to realize target localization. By dividing the localization equations and introducing new parameters, the localization problem is linearized and computationaldoi:10.12783/dtcse/msota2018/27563 fatcat:ykefggyjpfc6bmfz6ckv35jhk4
