Wireless localization based on the time sum of arrival and Taylor expansion

The localization of a wireless device is important for current wireless networks, therefore this paper investigates the time-sum-of-arrival (TSOA) based localization method, where the Taylor Series algorithm is analytically derived according to the elliptical geometry, i.e., TSOA based Taylor Series method, and then the conventional time-difference-of-arrival (TDOA) based algorithm is provided as a comparison. The simulation shows that the TSOA based algorithm has a better performance than the latter.
