Grid Based Field Strength Method for Mobile Vehicle Positioning
نویسندگان
چکیده
Various mobile positioning techniques are being used in different environments for location based services (LBS). In this paper, for position fixing a new method known as grid based field strength determination is proposed. Spatially scattered measured signal strength data is encoded into structured grid data using planar fit algorithm in forward estimation. In reverse estimation, a look up table is formed to identify the mobile vehicle location from grid point estimations. The position identification results are in well agreement with the observed results ( 50m accuracy).
