The design of a location services module (LSM) that provides a foundation for location-aware services is described. The architecture enhances application software development by providing a simple interface that hides details of the particular underlying location determination technologies. Functions for multiple technology switching, error estimation, location tracking, multiple technology fusion and cooperative location determination are defined. Several self-organizing protocols for cooperative location determination algorithms appropriate for wireless ad hoc networks are described. An example implementation of location-based services for a world wide web browser using an LSM is provided.
