A service oriented location-aware system

Location-aware systems have attracted a lot of attention from both academic and industrial users. Location detection or positioning devices are integrated with the system in order to get location information. Bluetooth is often used to detect the users' location in indoor location-aware applications. This paper presents a service-oriented method to integrate the Bluetooth-based location detection devices with the location-aware application. The service-oriented method provides more flexibility and extensibility of the system. The prototype of CPH AirNotes with Blip devices is developed to show that the proposed method is effective. Also the performance of the Blip devices is discussed.
