G. Chandrasekaran, M.A. Ergin, M. Gruteser, R.P. Martin, Jie Yang, Yingying Chen
2009 IEEE Transactions on Mobile Computing  
The positioning errors from indoor RSS-based localization systems tend to be too large, making it difficult to detect whether two devices are moving together based on the interdevice distances.  ...  We further show that DECODE is generic and could accomplish detection for mixed mobile transmitters of different technologies (IEEE 802.11b/g and IEEE 802.15.4), and our results are not very sensitive  ...  DECODE uses the Pearson's product moment correlation coefficient [22] , a preferred method for quantitative measures such as the RSSI traces used.  ...

DIRECT INFERENCE OF LOCATION-RELATED CONTEXT FROM WIRELESS SIGNAL STRENGTH Direct Inference of Location-related Context from Wireless Signal Strength

Gayathri Chandrasekaran, Marco Gruteser, Richard Martin, Gayathri Dissertation, Marco Gruteser, Richard Martin
unpublished
We apply correlation and time warping algorithms to the time series of wireless signals to infer these properties.  ...  The key insight is that the time-series of signal strength is robust to environmental factors that typically negatively affect the RSS-based localization systems.  ...  The Localization algorithm, on the other hand, has a weak correlation with the actual speed of 0.34. We also calculated the Pearson's correlation coefficients for all the testing traces combined.  ...
