With the rapid development of Smartphone
industry, various positioning enabled sensors such as GPS
receivers, accelerometers, gyroscopes, digital compasses,
cameras, Wi-Fi and Bluetooth have been built in smart
phones for communication, entertainment and locationbased
services. Smartphone users can get their locations
fixed according to the function of GPS receiver. This is the
primary reason why the huge demand for real-time location
information of mobile users has been unprecedented in
recent years. However, the GPS receiver is often not
effective in indoor environments due to the signal
attenuation and multipath effects, although it as the major
positioning devices have a powerful accuracy for outdoor
positioning. This research investigates other built-in sensors
and develops methods for improving the accuracy of indoor
positioning. Combination with the wireless network, it can
be a viable alternative solution for the indoor positioning
purposes of the smart phone users. The main advantage of
this solution is that it can be deployed with a minimal cost,
as no specialized hardware is necessary for setting up the
system. However, challenges remain for this solution due to
complex indoor environment involved and extensive
calibration data overhead.

Since IEEE wireless protocol was released about ten years
ago, Wi-Fi technical standards have been well developed
and widely used due to the high speed, wireless
connectivity and large coverage of the Wi-Fi technology.
Nowadays the demand for real-time location information of mobile users is unprecedented. For outdoor
environments, using GPS can achieve high accuracy
positioning results. However, in indoor environments, due
to the attenuation or obstruction of GPS signals, GPS
technology cannot be used effectively. Therefore, Wi-Fi
based positioning technology has been researched and
developed for indoor environments.
