On-demand fingerprint selection for 802.11-based positioning systems

Thomas King, Thomas Haenselmann, Wolfgang Effelsberg
2008 2008 International Symposium on a World of Wireless, Mobile and Multimedia Networks  
Fingerprinting is a popular technology for 802.11based positioning systems: Radio characteristics from different access points are measured at various positions and stored in a database.  ...  We carefully evaluate our algorithms in a real-world experiment. The results show that our algorithms do not harm the position accuracy of the positioning system.  ...  We are not going to describe these changes here because they are out of scope of this paper.  ...

A ranging scheme for asynchronous location positioning systems

Hakyong Kim
2009 2009 6th Workshop on Positioning, Navigation and Communication  
In this paper, we propose an asynchronous two-way ranging scheme which reduces ranging time by replying with multiple packets to a single ranging request.  ...  In a real-time locating system which does not require time synchronization among nodes, it takes a very long time to complete a ranging process for a single location estimation.  ...  In usual wireless sensor networks, data rate of the wireless communication channel is narrower than 1 Mbps.  ...
