Abstract
An effective location algorithm, which considers non-line-of-sight (NLOS) propagation, is presented. By using a new variable to replace the square term and adding the loose variable, the problem becomes a mathematical programming problem, and then the NLOS propagation´s effect can be evaluated. This method is simple and does not add much computation time. Compared with other methods, it has high accuracy.
