The technique of radio frequency identification (RFID) is very suitable for medical affairs due to its low-power transmitting frequency and wireless tracking capability. It has currently been used in many medical centers for tracking highly contagious and dangerous patients. In this paper we propose an improved concurrent search algorithm to find patients’ locations quickly by RFID. It is mainly based on patients’ moving regularity in medical environments to find RFID tags efficiently on a hierarchical
RFID architecture. Experimental results also show the performance of the proposed approach.
