Modeling location for pervasive environments

The representation of spaces, locations and the entities they contain is of great importance to location aware systems and pervasive computing scenarios. There has been an active research community in developing many diverse models of location, resulting in significant progress in the area. Various types of location model have evolved through experiment and experience however there still remains many challenges to be met by the research community. This paper aims to highlight previous trends in location modeling, discuss the research challenges ahead and to outline the initial design of a location model for the Strathclyde Context Infrastructure [?].
