Client Based Wireless LAN Indoor Positioning

The number of wireless users, applications and network access technologies is constantly growing. This trend supports the vision of pervasive computing where users have network access anytime and anywhere. Furthermore applications become location-sensitive and context-aware. Wireless LAN technologies are the ideal mechanism for extension of network connectivity to public places (such as airports, shopping centers, hotels, parks) and introduction of location and context-aware applications. Traditional WLAN user positioning techniques include the strongest WLAN access point and RF fingerprinting methods. In this paper an enhancement of triangulation method with RF propagation loss algorithm is proposed and compared with traditional methods. All evaluations are based on experimental results in real WLAN environment. Experimental results confirm the advantages of the proposed method.
