A Review On Map-Based Indoor Positioning Techniques

In this study, a review of indoor positioning methods based on indoor environment models is presented. Researchers introduce a variety of methods in this field. The purpose of this study is to present different methods and evaluate them. Each method is described from the point of view of the use of the spatial models. In the end, methods advantages and disadvantages have been introduced. Due to the wide variety of methods and Principles used in this field, the choice of an optimal method is not possible. Because each one has a different performance depending on the indoor environment and problem. It seems that, if it is possible, a combination of methods is an effective solution, because in some cases the advantages of a method cover the disadvantages of another method.
