Abstract: Provided is a node location tracking method, including an initial localization step of estimating initial locations of a robot and neighboring nodes using inter-node measurement and a Sum of Gaussian (SoG) filter, wherein the initial localization step includes an iterative multilateration step of initializing the locations of the nodes; and a SoG filter generation step of generating the SoG filter.
