The steady rise of mobile computing devices and wireless local-area networks (WLAN) has fostered a growing interest in location-aware systems and services (LBS). Context-awareness in mobile systems give users more convenience with services specific to their preferences, behaviour and physical position. This paper presents an architecture for LBSs in WLANs describing the essential location determination component. An example service using Web Service techniques is described to illustrate efficient service invocation and interaction.
