Mobile Reader Selection for Improving Precision of Location Estimation in RTLS
Jam-Je Kim, Sanghyun Son, Hoon Il Choi, Yunju Baek · 2010
RTLS (Real Time Locating Systems) are used to track and identify the location of objects in real time. RTLS generally consist of tags, readers and engine etc. and applied in various environments. One problem encountered in RTLS is constraints for setting up readers according to environments. In these challenging environments, it is necessary to develop techniques that can use mobile readers. As mobile reader increase, whole reader increase. And it is necessary to develop technique that can select useful readers. Selected readers including mobile readers take effect performance of RTLS. This paper introduces the technique for selecting good readers using the convex hull algorithm. The result show the good performance which based on tag's location error and reduce the networking overhead.
