Location-based service provisioning is of great interests to wireless Internet service providers (WISPs) to deliver attractive value-added services, such as service advertisements, product marketing, to the special network users according to their geographic coordinates, along with Internet access benefits. It is usually the case that the basic location information is derived from direct interactions...
With the proliferation of wireless communication technologies and mobile computing devices, research interest has grown for location-aware systems and services. We propose LAAC, a novel location-aware access control protocol based on a coarsely defined location area that is enclosed by overlapping areas of multiple access points. Accordingly, a location key for location claim is derived from the overlapping...
