Positioning and routing in an outdoors environment is still challenging especially in complex buildings, where a number of buildings are combined with tunnels and bridges, and the GPS signal is unreachable. Wasting time for looking for a particular room in an unfamiliar huge indoor environment or a product in an enormous store is a real life problem that everybody faces on daily basis. The paper represents a solution for addressed problem by using Ekahau positioning systems and Android OS through an intermediary server, which acts between these two systems to provide actual room level position on a map by mathematical modeling technique. The system also based on request provides shortest path for a certain destination by computing Dijkstra's search algorithm. The distance between the locations is defined based on Taxi-cab geometry distance definition for the mobile clients. Additionally, the users can also display shortest path for some nearest items such as coffee machine. The implemented system evaluations are carried out in a basement floor on the site. ; Godkänd; 2014; 20140307 (karand)
