摘要：Computation RFID (CRFID) expands the limit of traditional RFID by granting computationalcapability to RFID tags. RFID tags are powered by Radio-Frequency (RF) energy harvesting.However, CRFID tags need extra energy and processing time than traditional RFID tags tosense the environment and generate sensing data. Therefore, Dynamic Framed Slotted ALOHA(DFSA) protocol for traditional RFID is no longer a best solution for CRFID systems. In thispaper, we propose a table-based CRFID tag identification protocol considering CRFIDoperation. An RFID reader sends the message with the frame index. Using the frame index,CRFID tags calculate the energy requirement and processing time information to the readeralong with data transmission. The RFID reader records the received information of tags into atable. After table recording is completed, the optimal frame size and proper time interval isprovided based on the table. The proposed CRFID tag identification protocol is shown toenhance the identification rate and the delay via simulations.
