Abstract
Multitag identification is one of the main advantages of the radio frequency identification (RFID) system. In the RFID system, the capture effect often happens in the real environment. When the capture effect occurs, the reader will not completely identify the tags in its scope. In many RFID applications, to get the real-time number of tags, the reader identifies the tags repeatedly. In these cases, the tag in the reader's scope is a staying tag or an arriving tag. The reader already stores the IDs of all staying tags, so it can just verify the existence of these tags to rapidly identify them. As a result, the reader can spend the main time in recognizing arriving tags. To cope with the capture effect and identify staying tags rapidly, this paper presents a collecting collision tree protocol for RFID tag identification with capture effect (CCT). In CCT, a collecting mechanism is adopted and a lot of staying tags can be recognized in a slot. What is more, the reader can identify all tags in its range when the capture effect happens. Finally, various analysis and simulation results show that CCT outperforms the existing algorithms significantly.
Highlights
Radio frequency identification (RFID) is a noncontact automatic identification technology [1], which is one of the most important technologies of the internet of things (IOT)
We simulate the performance of capture effect (CCT) in Ti+1 by comparing it with multiround collision tree (MRCT), generalized binary tree protocol (GBT), general query tree 1 (GQT1), and general query tree 2 (GQT2)
When we evaluate the effects of ra on the performance of CCT, MRCT, GBT, GQT1, and GQT2, Table 2 depicts the simulation parameter settings
Summary
Radio frequency identification (RFID) is a noncontact automatic identification technology [1], which is one of the most important technologies of the internet of things (IOT). The RFID system has been widely used in locating and tracking, warehouse management, goods inventory, and other aspects of daily lives [2, 3]. The main components of the RFID system are reader and multiple tags. When multiple tags send information to the reader simultaneously, collisions between these tags’ signals will cause that the reader cannot receive the tags’ data correctly. The colliding tags need to retransmit their IDs to the reader to be identified. The retransmitting will increase the reader’s identification delay and waste spectrum resources. We need to propose effective tag anticollision algorithms to solve the problem of collision between tags
