In this paper, we propose a new algorithm to improve the accuracy of indoor positioning techniques usingWi-Fi access points as beacon nodes. The proposed algorithm is based on the Weighted Centroid algorithm, apopular method widely used for indoor positioning, however, it improves some disadvantages of the WeightedCentroid method and also for other kinds of indoor positioning methods, by using the received signal strengthcorrection method and genetic algorithm to prevent the signal strength fluctuation phenomenon, which is causedby the complex propagation environment. To validate the performance of the proposed algorithm, we conductedexperiments in a complex indoor environment, and collect a list of Wi-Fi signal strength data from several accesspoints around the standing user location. By utilizing this kind of algorithm, we can obtain a high accuracypositioning system, which can be used in any building environment with an available Wi-Fi access point setup asa beacon node.
