Optimum Frame-length Configuration in Passive RFID Systems Installations
نویسندگان
چکیده
Anti-collision mechanisms in RFID, including current standards, are variations of Aloha and Frame Slotted Aloha (FSA). The identification process starts when the reader announces the length of a frame (in number of slots). Tags receive the information and randomly choose a slot in that cycle to transmit their identifier number. The best performance of FSA always requires working with the optimum frame-length in each cycle. However, it is not a parameter easy to adjust in real RFID readers. In this work a markovian analysis is proposed to find the optimum value of frame-length for the current readers of the market. Besides, to validate and contrast the analytical results, a real passive RFID system has been used to get experimental results: the development kit Alien 8800. The experimental results match the analysis predictions.

On the optimal frame-length configuration on real passive RFID systems
The majority of the anti-collision protocols proposed for passive RFID systems are based on Frame Slotted Aloha (FSA). They assume a classical result in FSA-based protocols which states that the theoretical identification throughput is optimized when the number of competing tags in coverage equals the number of slots in the frame. However, this is not exact in real RFID systems, as the so-calle...

MAC level efficiency constraints of the RFID Reader-Tag communication require proper frame size selection in order to achieve maximum throughput. To set optimal frame size, one needs to estimate the number of tags. Deriving optimal frame size results in reducing time for identification of large RFID tag populations, and thus increases throughput of RFID system. In accordance with the standard D...

Radio Frequency Identification (RFID) system uses the principle of radiative power transfer between the reader and the tag antenna. The main performance metric for RFID system is the reliable reading coverage, where the tag can be read with higher detection probability. Most of current researches consider the reader coverage to be determined only by its read range assuming monostatic configurat...

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 ot...
