Wi-Fi based indoor navigation in the context of mobile services

With the increased prevalence of smartphones and online mapping solutions like Google Maps, the next logical step is the mapping of indoor spaces. Especially, in large public
buildings like airports and shopping malls, people may profit from these systems. There are a large number of mapping solutions available on the market today. Some of the most popular being Google Maps, OpenSteetMap, Bing Maps, and MapQuest. Google Maps and Bing Maps have both started offering indoor maps of a number of publicly accessible buildings, but these solutions are proprietary, and only data that is approved by these companies is accessible on their services. The goal of this thesis is to provide a framework upon which an indoor mapping solution with the following properties can be developed: Indoor positioning, map of the indoor space, smartphone application that can access the map data and the position service, and a routing system that can give a user firections between rooms or from the users position to a room.
