Comparison of location estimation accuracy in Wi-Fi – indoor positioning system
1. Introduction:

Indoor positioning technology is an important issue to be addressed for providing any kind of location based services. There were lot of approaches for this technology by the user of active sensors like active badge, active bat, etc. (Hightower and Borriello, 2001), and some approaches use the in-building Wi-Fi networks for indoor positioning. The use of Wi-Fi signals as a potential positioning system within buildings has opened doors for many applications. Lot of research is being undertaken in this domain to find a more viable solution of location positioning using the Wi-Fi signals within the building with higher accuracy. This is because of the ubiquitous availability of Wi-Fi signals in almost all the buildings, so no additional hardware is required to install a positioning system in the buildings.
