Design of Hash-Tree Anti-collision Algorithm
Third International Conference on Natural Computation (ICNC 2007) Vol V, 2007In RFID system, the problem of the collision between tags is a focus topic. The Hash-tree anti-collision algorithm was proposed in the paper, which adopted hash operation to allocate slots for tags and used tree searching method to identify collision tags in the queue of collision slots.

Parallel Splitting for RFID tag anti-collision
International Journal of Ad Hoc and Ubiquitous Computing, 2011In the Radio Frequency IDentification (RFID) system, the reader identifies tags by interrogating their IDs through a shared wireless communication channel. When multiple tags transmit their IDs to the reader simultaneously, collisions occur and the performance of tag identification degrades.

A new anti‐collision algorithm for RFID tag
International Journal of Communication Systems, 2013SUMMARYWe present a new radio frequency identification tag anti‐collision algorithm in this paper. The main idea of this algorithm is that we should find the collided bit at first, and every tag contains a register RC, which has length the same as the tag's ID length to store the conflict bit, then all the subsequent processing are based on the ...

A New anti-collision protocol for RFID networks
2014 Wireless Telecommunications Symposium, 2014The speed at which RFID tags are read is critical to many RFID applications. Tag collisions can increase the time to gather information from tags in RFID networks. These collisions are unavoidable; however the time spent on them can be reduced using an intelligent medium access protocol.

Both the argument and the geometry in this paper require careful study before they can be appreciated; it is hoped that the following notes, which are restricted to purely geometrical considerations, will assist readers to understand them.The author's fundamental argument is that it is geometrically impossible for ships A and B, at distance r apart and

Development an approach to fusion of an anti-collision system
2014 International Conference on Advanced Logistics and Transport (ICALT), 2014In most cases, the man is the cause of the accident. The work presented in this article to develop an anti-collision system, which aims to assist the driver and reduce road risks. The sensors are of great importance in this system, they have provided for each measurement time, a list of objects on the distance and angular position.

Silence Coding for RFID Tag Anti-Collision
2016 IEEE 41st Conference on Local Computer Networks (LCN), 2016This paper proposes a tree-based RFID tag anti-collision protocol, called the silence coding query tree (SCQT) protocol, based on a novel coding scheme, namely the silence coding, to speed up tag identification. The proposed protocol can identify multiple tags at a time even at the appearance of tag signal collisions.

Dynamic adjustment algorithm for tag anti-collision
2011 International Conference on Machine Learning and Cybernetics, 2011RFID (Radio Frequency Identification) is one of the key automatic identification technologies. Along with the large-scale application of RFID tags, the tag collision problem becomes more frequently and seriously affects RFID system performance. In this paper, according to the characteristic of disordered and successive tag ID number, we propose a ...

The Impact of External Interference on RFID Anti-Collision Protocols
IEEE Networking Letters, 2019Research on RFID has made significant progress in reducing the tag identification time, but almost ignored the concerns related to practical system deployment. RFID tags backscatter to the reader a signal that is weak and subject to interference from any nearby device operating on the same frequency, experiencing significant performance degradation ...
