Unified Q-ary Tree for RFID Tag Anti-Collision Resolution
Radio Frequency Identification (RFID) technology uses radio-frequency waves to automatically identify people or objects. A large volume of data, resulting from the fast capturing RFID readers and a huge number of tags, poses challenges for data management. This is particularly the case when a reader simultaneously reads multiple tags and Radio Frequency (RF) collisions occur, causing RF signals...
متن کاملAnti-collision Algorithms for Multi-Tag RFID
RFID is one of automatic technology to identify and collect object data quickly through RF digital signals. RFID increases productivity and convenience. RFID is used for hundreds, if not thousands, of applications such as preventing theft of automobiles and merchandise; gaining entrance to buildings; automating parking. But one of the largest disadvantages in RFID system is its low tag (transpo...
متن کاملPerformance Analysis of Tag Anti-collision Algorithms for RFID Systems
Lately, the ISO fixed on UHF Gen2 as one of the standard protocols for RFID, called ISO 18000-6 C, along with ISO 18000-6 A/B. It means that the RFID system should provide the multi-protocol support for tag identification and a proper protocol should be chosen depending on the situation. The tag anti-collision algorithm is one of the important research issues to be on top of the protocol’s perf...
متن کاملInstant collision resolution for tag identification in RFID networks
In this paper, we approach the problem of identifying a set of objects in an RFID network. We propose a modified version of Slotted Aloha protocol to reduce the number of transmission collisions. All tags select a slot to transmit their ID by generating a random number. If there is a collision in a slot, the reader broadcasts the next identification request only to tags which collided in that s...
متن کاملAdaptive collision resolution for efficient RFID tag identification
In large-scale RFID systems, all of the communications between readers and tags are via a shared wireless channel. When a reader intends to collect all IDs from numerous existing tags, a tag identification process is invoked by the reader to collect the tags’ IDs. This phenomenon results in tag-to-reader signal collisions which may suppress the system performance greatly. To solve this problem,...
