There are currently two classes of Location Based Services (LBS), namely those that are dependent on an aggregation infrastructure and those that are inde- pendent of an aggregation infrastructure. The goal of this research is investigate the latter.

The purpose of this research is to explore the possible location of this class of LBS on a mobile device (mobile phone) in order to achieve maximum portability. In addition to this, this research will establish how the source of the location information ( GPS, Cell Tower Triangulation, WiFi triangulation) partition this class of LBS.

  The challenge of this research would to be to a develop a service that is portable across different mobile devices running di erent operating systems.
