The survey of indoor positioning algorithms for mobile devices

This paper provides an overview of algorithms for local (indoor) positioning on the basis of Wi-Fi standard and the method of RSS (received signal strength), in which the only source of information on the location of the user performs the signal strength received from access points of Wi-Fi network. Comparative analysis of algorithms being executed on criteria such as basic or improving, error, computational complexity and independence from preliminary measurements. Also covers basic filters used to obtain estimates of the strength level of the received signal.
