A Simple and Efficient Anti-collision Algorithm for RFID System

2010 Sixth International Conference on Intelligent Information Hiding and Multimedia Signal Processing, 2010
Radio Frequency Identification (RFID) has recently played an important role in wireless sensing network. However, if multiple passive tags are simultaneously transmitted to the reader, the reader is unable to identify the tags. This will reduce the efficiency of a RFID system.

An efficient tag anti-collision protocol for RFID systems

2012 IEEE 2nd International Conference on Cloud Computing and Intelligence Systems, 2012
In low-cost RFID systems, efficient anti-collision protocol of passive tags is very desirable for fast identification. In this paper, we propose a new anti-collision protocol: assigned tree slotted aloha anti-collision protocol. The key technology is to assign prefixes to each frame and slot respectively such that tags can match the frame recognition ...

A new anti-collision method for RFID systems

2011 IEEE 12th International Symposium on Computational Intelligence and Informatics (CINTI), 2011
Anti-collision technology in RFID system plays an essential role in the process of recognizing tags. Framed-Slotted structure makes it more convenient and effective for ALOHA anti-collision algorithm. But when the number of tags, especially the range of tag number, is unknown, it will be very hard for the system to initialize the suitable frame size ...

Neural anti-collision system for Autonomous Surface Vehicle

Neurocomputing, 2015
Autonomous Surface Vehicles (ASV) are robots destined for the operation at water basins like lakes, canals, harbors and even open sea. They are used for different purposes, e.g. for patrol tasks, as scouts, or as a support for Navy ships. One of the main tasks of ASV is to move along a fixed path to a destination point.

An Improved Anti-collision Algorithm for ISO15693 RFID Systems

2012
The Radio Frequency Identification (RFID) is an important technology of the Internet of Things. Along with the rapid growth of the RFID technology, security issues have acquired much attention recently. However, most of the RFID security works focus on fake identity or information leaking problems.

A Fast Algorithm for Anti-Collision in RFID System

Advanced Materials Research, 2013
This paper proposes a fast query tree-based (FQT) algorithm for anti-collision in RFID system. Tags to be identified would be grouped by a reader randomly at beginning, and the reader identifies a group of tags and records the quantity of tags. Then reckons the number of all tags and carries out optimized group again.

An Improved Anti-Collision Algorithm in RFID System

Applied Mechanics and Materials, 2013
Tag collision problem is the key issue that affects the reading efficiency of the RFID system. This paper presents an improved binary tree anti-collision algorithm based on the jump dynamic tree.We used stack technology, backward strategy to avoid the reader identifying the tag from the tree roots.

Dynamic Anti-Collision System for Hydraulic Cranes

IFAC Proceedings Volumes, 2011
Abstract The need for dynamic anti-collision systems is rapidly increasing. The future stopping positions of a crane and its neighbor cranes are predicted, which allows to stop the cranes on time to avoid collision. The brake path calculation includes reaction times and is realized via kinematical transformer.
