A DHT-Based Discovery Service for RFID Network

RFID tags are widely used in recent years. Discovery service (DS) for RFID Network is a pivotal system that serves the following lookup function: Given the RFID identifier of an object, it returns a list of Internet addresses of servers which offer detailed information about this object. The existing researches on DS have severe drawbacks in being compatible with different RFID standards and scalability. Therefore in this paper, a novel DS solution based on DHT is proposed to solve those problems. Moreover, any cast technique is adopted to further improve its performance. Compared with the existing researches on DS, our DS solution is compatible with different RFID standards and has better scalability. By experiment, the average service time of our DS system is close to that of the existing DS systems based on DHT, which is acceptable to the user.
