Smart Batch-Processing Protocol for RFID Multiple Tag Identification

Perfect tag identification protocol in RFID networks

Radio Frequency IDentification (RFID) systems are becoming more and more popular in the field of ubiquitous computing, in particular for objects identification. An RFID system is composed by one or more readers and a number of tags. One of the main issues in an RFID network is the fast and reliable identification of all tags in the reader range. The reader issues some queries, and tags properly...

A hybrid randomized protocol for RFID tag identification

Purpose – Radio frequency identification (RFID) is a technology for tracking objects that is expected to be widely adopted in very near future. A reader device sends probes to a set of RFID tags, which then respond to the request. A tag is recognized only when it is the only one to respond to the probe. Only reader has collision detection capability. The problem considered here is to minimize t...

Smart RFID Tag for Diaper Moisture Detection

Beyond the limit: A fast tag identification protocol for RFID systems

This paper presents the design, experiment test and performance evaluation of FAST, a fast tag identification protocol in RFID systems. FAST includes a collision tolerant mechanism (CTM) that can identify tags in collision slots correctly. Each tag sends a randomly selected signature in its selected slot. When multiple tags select the same slot and a collision occurs, the reader can detect all ...

A Novel and Efficient Anti-Collision Protocol for RFID Tag Identification

Radio frequency identification (RFID) is prominent technology for fast object identification and tracking. In RFID systems, reader-to-reader or tag-to-tag collisions are common. Majority of probabilistic and deterministic anticollisions methods are inefficient in channel distribution and improving the performance. In this work, simulation annealing based anti-collision protocol is proposed wher...
