Critical Review Of Indoor Positioning Systems

There has been a long-standing need for a robust Interior Positioning System that may be used in a variety of indoor settings. It is impressive how many different kinds of technologies, methods, and approaches are incorporated within IPS proposals. As a result of this variety and the absence of rigorous and verifiable evaluations, it is sometimes difficult to determine the genuine worth of most ideas. In order to have a full picture of the state of the art in indoor placement, this paper presents a meta-review that synthesizes numerous survey studies. The paper introduces the concept of IPS and the many technologies, strategies, and approaches that are used to implement it. The introduction is backed up by common ground discovered in the aforementioned studies, which are cited as sources. To that end, the meta-review provides a high-level overview of the current state of IPS and directs the reader to where they may learn more about each technology employed by IPS. Using citation counts as a metric, the meta-studies review shed light on the sheer volume and scholarly weight of published IPS proposals
