Abstract
This paper proposed a novel wireless location algorithm based on distance geometry (DG) constraint filtering for the time of arrival (TOA) of the signal (namely as DG-TOA). Filtering and processing of the observed data and leading to the mathematical formulas based on DG-TOA algorithm are applied to location, also play crucial rules. Simulation results show that the proposed DG-TOA algorithm can provide more valid observation data and be more precise than least square estimate (LSE) algorithm in dense, multi-route, indoor circumstances with the ranging estimation error.
