What is TDOA localization?
The key concept of TDOA-based localization technique is to determine the location of the source by evaluating the difference in arrival time of the signal at spatially separated base stations.
How is TDOA calculated?
TDOA Calculation
In the first method, each receiver measures the absolute time instant of signal arrival (time-of-arrival or TOA) as defined by t i above. A difference in time-of-arrivals between two receivers is then calculated to obtain the TDOA measurement.
What is TDOA in WSN?
The location information of sensors is of great importance for wireless sensor networks. In this paper, we propose a new localization algorithm for the wireless sensor network based on time difference of arrival (TDOA), which is a typical algorithm in the wireless localization field.
