Wireless localization plays an important role in the internet of things, such as the wireless sensor network and the smart grid. Therefore this paper investigates the time-sum-of-arrival (TSOA) based localization algorithm, where a two-step weighted least-squares algorithm is analytically derived according to the elliptical geometry. Meanwhile, the comparison between the proposed algorithm and the conventional time-difference-of-arrival (TDOA) algorithm is provided in detail. The simulation shows that the TSOA based algorithm produces a better performance than the TDOA based one in the environment with large range measurements.
