NavTag: An inter-working framework based on tags for symbolic location coordinates for smart spaces

Abstract

Location information and sensor networks are key ingredients in realizing smart spaces by customizing the behavior of the application according to users' locations and by being able to sense and act upon the physical space. This paper presents a flexible interworking model for complex smart space environments, in which points of interest are represented as tags, while spatial representations are achieved by representing the physical space as a tag space encoding a quadtree. The mechanism is beneficial for reducing the modeling and maintenance costs of location in smart spaces, as well as providing a low entry barrier for integration with other information systems. © 2009 Springer Berlin Heidelberg.
