Abstract: | The algorithm of LANDMARC is introduced in this paper ,which widely used in indoor positioning system . Then the basic principle of the algorithm is analyzed and the simulation process in MATLAB is given .An optimization method based on the number of energy level was put forward to minimize the error and improve the accuracy of positio-ning .Simulation results show that by increasing the number of energy level ,the positioning accuracy can be improved in the case of other factors unchanged . |
