Abstract

Localization is used more and more often, not just used to navigate people but also for tracking objects for different purposes. The global positioning system is a well-known system but it is not appropriate for use in some situations such as indoor or built-up areas. A solution in these places is positioning using the internet of things. In recent years, it has gained popularity due to increased internet of things nodes. This paper provides an overview of different approaches to localization and provides a survey of data used for localization as well as different localization methods. At the end, we describe the experiment performed using LoRa technology with four anchor nodes. To estimate the position of the node received signal strength was measured and position was estimated by both trilateration and Min-Max algorithms. The experiment was performed in an open space.
