Abstract: In this paper, two location algorithms, i.e. Chan and Taylor series expansion methods, are analyzed and a cooperative location method based on Chan and Taylor algorithms is proposed. The performance of the cooperative location method is simulated under different channel environments, and the results show that the cooperative location method can significantly improve the location accuracy under bad channel environments. -
