AN RFID BASED PROXIMITY MEASUREMENT OF OBJECTS IN SMART ENVIRONMENTS

Ambient Intelligence considers responsive environments in which applications and services adapt their behavior according to the user's needs and changing context. One of the most challenging aspects for many applications in Ambient Intelligence environments is location and Orientation of the surrounding objects. This is especially important for effective cooperation among mobile physical objects in such smart environments. We propose a robust indoor positioning system that provides 2D positioning and orientation information for mobile objects. The system uses passive Radio Frequency Identification (RFID) technology. The proposed system consists of passive RFID tags and readers. The readers are used to identify the location and the orientation of the objects with respect to the surrounding objects. The results can be shown by using the lab view software. The advantage of the proposed system compared to the existing system is that the proposed system finds the orientation of the object with respect to the surrounding objects
