A Frame Size Adjustment with Sub-Frame Observation for Dynamic Framed Slotted Aloha
نویسندگان
چکیده
In this paper, a simple frame size adjustment of dynamic framed slotted Aloha for tag identification in RFID networks is proposed. In dynamic framed slotted Aloha, the reader is required to announce the frame size for every frame. To achieve maximum system efficiency, it is essential to set the frame size according to the number unidentified tags appropriately. The proposed approach utilizes the information from a portion of the frame to adjust the size of the next frame. Simulation results show that the smaller number of observed slots results in faster frame adjustment and higher throughput. Compared to the existing anti-collision algorithms, the proposed approach achieves higher throughput and higher identification rate. Keywords—anti-collision tag identification; RFID; Framed slotted Aloha; frame adjustment

Novel Dynamic Framed-Slotted ALOHA Using Litmus Slots in RFID Systems
Dynamic Framed Slotted ALOHA (DFSA) is one of the most popular protocols to resolve tag collisions in RFID systems. In DFSA, it is widely known that the optimal performance is achieved when the frame size is equal to the number of tags. So, a reader dynamically adjusts the next frame size according to the current number of tags. Thus it is important to estimate the number of tags exactly. In th...

In this paper, we study Radio Frequency IDentification (RFID) tag identification problems using Framed Slotted ALOHA (FSA) protocol. Each tag will be assumed to participate in the contention with a certain probability. Then, the frame size and the probability will be dynamically controlled by the reader in every reading round so that all the tags can be detected in a short period of time. Moreo...

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 کاملAn Enhanced Dynamic Framed Slotted ALOHA Anti-collision Algorithm
In RFID system, one of the problems that we must solve is the collision between tags that may occur when a reader attempts to read a number of tags simultaneously. Most of the popular anti-collision algorithms are based on the ALOHA-type algorithm, which are simple and show good performance when the number of tags to read is small. However, for ALOHA-type algorithms the time required to read th...
