摘要: Radio frequency identification (RFID) enables everyday objects to be identified, tracked, and recorded. The RFID tags are must extremely simple of low cost suitable for large scale application. An efficient anti-collision mechanism have access latency power consumption. This paper investigates how recognize multiple within the reader's interrogation ranges without knowing number in advance by using framed ALOHA. To optimize consumption overall tag read time, a combinatory model was proposed analyze both passive active with consideration on capture effect over wireless fading channels. By model, parameters set estimation frame size update were presented. Simulations conducted verify analysis. In addition, we come up proposal combat deterministic algorithms.
