This paper analyzed the relationship between the nearest neighbour algorithm and the topology of reference tags used in LANDMARC, and proposed an optimal arrangement of reference tags. Simulation results showed that the new topology can provide better performance than the old one used in LANDMARC. In This paper we introduce a new positioning algorithm for RFID tags using two mobile RFID readers and landmarks which are passive or active tags with known location and distributed.
In this paper active RFID tags are employed as reference points at known and fixed locations on a construction site and are used to calibrate the location estimation of other materials on the site. Materials on the site are uniquely attached with RFID tags and are subject to tracking. An RFID-based location sensing algorithm that uses virtual reference tags is designed and tested, which eliminates the need for collecting prior localization data, increases the accuracy of the location information, and potentially reduces the deployment costs. This work proposes a fine-grained method for 3-D range-free Localization of rfid tags with VIrtual Reference Tags (L-VIRT). Our algorithm is designed so as to be easily deployable over heterogenous RFID systems, usable with any equipment, and fast to be scalable.
Download figure: Standard image High-resolution image Let (X O, Y O) be the coordinates of the object/RFID tag.The tag response signal phases from one questioning to the next are recorded. In relation to the first response, the phase varies characteristically across a given distance for a particular tag position at the moment of the first reading.
RFID reference tags are deployed in a gridlike structure, where the horizontal distance of two neighboring tags might not be the same as the vertical distance. According to the indoor. The primary objective of this article is to understand and improve the performance of planar RFID tags operating at 13.56 MHz through numerical simulations based on structures generated by algorithms developed in MATLAB.
This paper investigates the usage of active RFID technology for the localization of movable objects (e.g. components, equipment, and tools) equipped with RFID tags using handheld readers by extending a Cluster-based Movable Tag Localization (CMTL) technique which uses a k-Nearest Neighbor (k-NN) algorithm. We propose a novel localization scheme aiming at the defects of existing RFID localization technology in localization accuracy and deployment cost, called ANTspin: Efficient Absolute Localization Method of RFID Tags via Spinning Antenna, which introduces a rotary table in the experiment.This paper analyzed the relationship between the nearest neighbour algorithm and the topology of reference tags used in LANDMARC, and proposed an optimal arrangement of reference tags. Simulation results showed that the new topology can provide better performance than the old one used in LANDMARC.
