Abstract:	State–of–art indoor positioning system cannot meet user requirement for indoor LBS. For practical use of mobile phone, indoor positioning system should be accurate and easy to use anywhere. Though RSSI based Wi-Fi indoor positioning is one of the most popular system owing to globally lots of pre-installed Wi-Fi APs, its accuracy is not good enough for indoor LBS. To solve the accuracy problem, this paper proposes new link based indoor map matching algorithm which utilizes PDR and digital map data as well as Wi-Fi signal. The implementation of the map matching method was evaluated in real time application and the result shows the new map matching algorithm enhances positioning performance more than 50%.
