Abstract

Location, as a form of context and as a specialised concern, has been a central consideration of pervasive computing from the start. Location, as a way of indexing data and through distribution of computation, has an even more venerable history in computer science. In this chapter we examine key issues in sensing and using location data, including: coordinate models, human descriptions and relations between locations; sensing of location, including GPS, cellular systems, trilateration and tags; and the storage and indexing of location data with R-Trees.
