Dynamic Grouping Frame-slotted Aloha
Passive UHF RFID systems using Dynamic Frame-Slotted ALOHA (DFSA) adjust the frame size according to the number of tags, but frame size N is equals to 2^Q and cannot be adjusted exactly to the number of tags to be identified. In this paper, we proposed a new Aloha based anti-collision algorithm which divides the tags and adjusts the frame sizes in such a manner as to always keep the system effi...
متن کاملAn adaptive Slotted ALOHA Algorithm
Slotted ALOHA channels are inherent instability and must be equipped with proper control. In this paper, we analyze the principle of ppersistent control algorithm (pPCA) at first, we propose a novel auto-control algorithm which combines the multiple factor into p-persistent autocontrol algorithm (MF-pPCA). The simulation demonstrates that the novel algorithm can accelerate the adjusting speed a...
متن کاملAn improved accelerated frame slotted aloha (afsa) algorithm for tag collision in rfid
The efficiency of tag identification in an RFID (radio identification system) can be low down due to the tag collision problems. The tag collision problem occurs when a reader try to read multiple tags in an interrogation zone. As a result, the reader doesn’t identify the tag correctly. That causes a loss of information or data interference. To solve such kind of issues a series of ALOHA based ...
متن کاملGrouping 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...
متن کاملA Fast Adaptive Control Algorithm for Slotted ALOHA
—The control algorithm which is in order to achieve the aim of keeping throughput stability is needed in the Slotted ALOHA(S-ALOHA) protocol. The core of the control algorithm is to derive the accurate number of nodes. The classic control algorithm suffers performance loss when the system nodes change. In this paper, we addressed a Fast Adaptive (FA) algorithm to promote the performance of ALO...
