I. Introduction
Recent advancements in the Internet of Things (IoT) have lead to the emergence of new applications, one of which being positioning, commonly known as localization. Localization in its simplest terms is the process of making something local to an area, which can be achieved through the use of indoor positioning systems (IPSs) and location-based services (LBSs). IPS is used in calculating the target’s location, while LBS uses the target’s location information to control features of the environment.
