Application background
A mobile RFID system including network domain, node domain and process domain based on OPNETthree-layer modeling mechanism is established to study the effect of anti-collision algorithm and multiple
environmental factors on tag recognition rate. Simulation results show that tag recognition rate of
CFDSE (Coarse-Fine Double Searching-based tag Estimation) method outperforms other three classical
algorithms 3.5%, 5.1%, and 7.2%, respectively.
Key Technology
Unlike RFID tags with fixed position in static environment, tags move through the reader with acertain speed and density in mobile environment. Tag recognition rate is influenced by the moving
speed, density and multi-tag anti-collision algorithm. High density and fast speed would result
in tags reading leakage. RFID has been widely used in manufacturing, supply chain management
and logistics since the 1980s as its
