摘要: The main objective of Radio Frequency Identification (RFID) systems is to provide fast identification for tagged objects. noteworthy advantage RFID technology, its capability identify objects simultaneously. However, when radio frequency signals are emitted simultaneously, there a probability collision occurrence, and thereby resulting in waste resources. Collision time-consuming event that reduces the performance systems. Consequently, several anti-collision algorithms have been proposed literature, attempt decrease occurrence probability. In almost all existing algorithms, prior knowledge number tags has significant role efficiency algorithms. Since real unknown, it needs be estimated. Therefore, more accurate estimation method results efficient process. Although, some methods previous researches, them suffer from either low accuracy level or high computational complexity. Moreover, most assume reader communication channel as an error free channel. Hence, environment, which error-prone, their not trustworthy. this presentation we will focus on general introduction Anti-Collision tag present advantages disadvantages methods.
