A Scheme to Increase Throughput in Framed-ALOHA-Based RFID Systems with Capture

Framed ALOHA for Multiple RFID Objects Identification

Radio frequency identification (RFID) enables everyday objects to be identified, tracked, and recorded. The RFID tags are must be extremely simple and of low cost to be suitable for large scale application. An efficient RFID anti-collision mechanism must have low access latency and low power consumption. This paper investigates how to recognize multiple RFID tags within the reader’s interrogati...

Framed Aloha Based Anti-collision Protocol for RFID tags

In this paper, we present evaluation performances of an anti-collision protocol for RFID tags. The protocol enables electronic markers, also known as smart labels or tags, to be identified. The principle of the protocol is the framed aloha with an optimization of the frame length. The optimization of this length is based on an evaluation of the number of active tags. Besides its performances, a...

LDFSA: A Learning-Based Dynamic Framed Slotted ALOHA for Collision Arbitration in Active RFID Systems

Grouping Based Dynamic Framed Slotted ALOHA for Tag Anti-Collision Protocol in the Mobile RFID Systems

Dynamic framed slotted ALOHA (DFSA) protocol has been widely used in many RFID systems. According to the information from last frame (e.g. the number of idle, success and collision slots), DFSA dynamically adjusts the next frame size so as to reach higher identification efficiency. The process is known as tag estimation of DFSA. Similar to most existing tag anti-collision protocols, The DFSA in...

a new type-ii fuzzy logic based controller for non-linear dynamical systems with application to 3-psp parallel robot

abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...
