| Abstract |
Abstract:<br/>In this work, we study the problem of tag identification in single and multi-reader<br/>RFID systems. First, we propose a novel solution to the reader-to-reader collisions<br/>and tag collisions in multi-reader systems, using the concept of bit tracking. Second,<br/>we explore the bit error types that could occur while using bit tracking. Although bit<br/>tracking has a significant contribution on decreasing the identification time, we define<br/>a bit error type coined mis-transition that occurs in bit-tracking based protocols only.<br/>In addition, we propose a novel technique that tackles mis-transition bit error.<br/>RFID systems consist of one or more readers and tags. Our main focus in this<br/>work is on battery free RFID tag which is known as passive tags. Passive tags harvest<br/>energy from RFID reader and follow the reader’s commands for collision resolving and<br/>slot assigning.<br/>In the first part of this work, we propose the multi-reader RFID tag identification<br/>using bit tracking (MRTI-BT) algorithm which allows concurrent tag identification,<br/>by neighboring RFID readers, as opposed to time-consuming scheduling. First,<br/>MRTI-BT identifies tags exclusive to different RFIDs, concurrently. Second, the concept<br/>of bit tracking and the proposed parallel identification property are leveraged<br/>to reduce the identification time compared to the state-of-the-art. Our simulation<br/>results exhibit considerable performance improvement with 113% reduction in the<br/>identification time, on the average, compared to Season algorithm [1].<br/>iv<br/>In the second part of this work, we investigate the bit errors that could occur while<br/>using bit tracking. Bit tracking based anti-collision algorithms have gained researchers<br/>interest due to their significant contribution in decreasing the identification time.<br/>They allow readers to detect the location of collided bits in a collision slot. However,<br/>through our deep investigation in bit tracking, we found a new significant bit error<br/>called mis-transition which increases the identification time. Mis-transition bit error<br/>is different from flipped bit error and it occurs when a reader mistakenly declares<br/>collision. In this work, we study and evaluate the effect of mis-transition bit error. In<br/>addition, we propose a zero cost algorithm that tackles this problem without using any<br/>coding scheme i.e, without adding extra coding bits. Tags may send their ID many<br/>times to resolve collision. We make use of the successfully received bits in collision<br/>slots to recover mis-transition bit error. Our simulations show the great potential of<br/>using repetition gain on recovering bit errors. |
