We propose a improved localization algorithm for indoor wireless TOA-based localization system. The purpose of the wireless localization system is how to reduce localization error not only in line-of-sight(LOS) but also in non-line-of-sight(NLOS), For reducing localization error, many approaches have been researched. In this paper, we proposed a new approach for reducing localization error. At the same environment, ranging results are not always same. Some factors have an effect on signal propagation and we called these factors biases. We proposed a new method which uses these biases. The simulation results show that a new method makes smaller overlapped area than conventional method and lead to reduce localization error.
