Scrutinizing Behavior of a Dynamic Framed Slotted Anti-collision Algorithm for RFID Systems
نویسنده
چکیده
Radio frequency identification systems with passive tags dramatically increase the ability of an organization to acquire a vast array of data about the location and properties of any entity that can be physically tagged and wirelessly scanned within certain technical limitations. However, if multiple tags are to be identified simultaneously, messages from the tags can collide and cancel each other out. One of the popular anticollision algorithms is the ALOHA-type algorithm, which is simple and has good performance when the number of tags to be read is reasonable small. In this paper we extended our previous research [8, 17] to build a more efficient dynamic framed slotted ALOHA for passive tags in RFID systems under the condition titled “maximum efficiency” [8]. Also the behavior of the ALOHA for RFID passive tags is investigated, which facilitates the future relevant research projects.

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...
متن کاملA Frame Size Adjustment with Sub-Frame Observation for Dynamic Framed Slotted Aloha
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 th...
متن کاملNovel 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...
