An important feature that is expected to be owned by today s mobile computing systems is the ability of processing locationdependent continuous queries on moving objects. The result of a location-dependent query depends on the current location of the mobile client which has generated the query as well as the locations of the moving objects on which the query has been issued. When a location-dep...

Emerging and continuing advances in ambient systems and localization techniques have brought novel opportunities to develop context-aware navigation services in indoor environments. Diverse kinds of services delivered to the users can be provided by enabling real-time integration of contextual dimensions. In particular, continuous location-dependent queries can be considered as key elements for...

Recent advances in mobile computing and mobile communication technology have led to the emergence of many innovative mobile-computing applications. Some of them require providing support to location-dependent continuous queries ( LDCQs) on moving objects. The result of a location dependent query depends on the current locations of the moving objects. When the query is specified as continuous, t...
