Indoor Navigation System

Abstract

Today it is possible to position wireless devices such as smartphones in an outdoor environment, using GPS, global positioning system.[1] Unfortunately this technology does not work in indoor environments. Being able to navigate smartphones indoors could be beneficial in many different environments. In hospitals when tracking hospital beds and patients, in prisons in order to track prisoners, in malls when a customer is searching for a store etc.[1] Indoor navigation could also be used to analyze human behavior. There are many different methods and techniques existing today that could benefit to an indoor navigation solution, all of them providing different results. Some are friendlier towards larger scaled areas providing less satisfying precision, meanwhile others provide higher precision but increases significantly in cost for larger scaled areas. In this project a significant amount of time was spent on researching different techniques for indoor positioning as well as analyzing the current state of the art and the[2] market of existing indoor positioning solutions. It provided a fully working solution to position on device. It created by the structure of the building and different objects in the indoor environment, together with a set of maps use to navigate. The work has resulted in a fully working server together with an android application.[3] The solution is an interesting approach to indoor navigation. It is fast and easy to set up and performs reasonably well compared to similar solutions.[4]
