Abstract: With the continuous development of universal computing research,indoor localization technology has become a hot topic in current research.Due to the complexity of the indoor space,enhancing the positioning accuracy of the indoor space has been unable to meet the needs of the application.In order to obtain a more efficient and stable algorithm,this paper proposed an indoor localization algorithm based on gradient and game theory.The algorithm can more effectively improve the positioning accuracy in indoor space.In the algorithm,a method of dividing the indoor space based on the symbol is proposed.At the same time,it segments the indoor space to support localization.Finally, the results of experimental validation of the algorithm show that the algorithm has good effect,and has more stable effect than the exi-sting algorithm.
