An improved RFID data encoding scheme for cycling path problem

With the widespread application of RFID technology,the efficient management of the huge amount of RFID data is very important. In the application of supply chain management, the key point is how to record and process the movement trajectories of objects. Based on a path encoding method by prime numbers, we propose an improved encoding scheme that encodes the flows of objects. It solves the problem of encoding a path with cycles, which we call “cycling path”. It can be proved that our approach is feasible and the original path can be restored by decoding. The proposed encoding scheme can be applied to more practical applications. Experiment results show that it has good performance when processing queries.
