Field simulation for RFID-based in door location sensing algorithm

In recent years, positioning systems for indoor areas using the Radio Frequency Identification (RFID) infrastructure have been suggested. Such systems make use of location fingerprinting algorithm for determining the location of object carrying RF tag. However, due to the environmental influence, theoretical model for these algorithms often fails to function in real world application, which necessitates sufficiently testing of any proposed system. Our project aims at providing a simulator which leverages Ptolemy environment to support high-fidelity simulation of RF system. By this simulator, developers can evaluate their locating algorithm before expensive road-test. The hypothetic RF signal propagation model is introduced. And a sample algorithm, LADDMARC, is implemented to evaluate our simulator.
