高效的功率可控防碰撞算法
Efficient anti-collision algorithm based on power-control
摘要
Abstract
The technology of multi-tag anti-collision is the key in radio frequency identification (RFID) system, in view of the existing problem that ALOHA anti-collision algorithms consume a lot of time solts and energy, an efficient anti-collision algorithm based on power-control is proposed. First, the UUID of tags will be done hash coding and the tags will be mapped to the corresponding slots in this algorithm to improve the utilization rate of slots. Then, collision detection mechanism allows only non-collision tags to communicate with the reader, thereby greatly reduces the ineffective communication process. Finally, the power-control mechanism to identify the tags by region significantly reduces the tag collision and saves the energy consumption of communication. It is found from the analysis of simulation results that the performance of the algorithm has been improved significantly compared with the existing anti-collision algorithms. It can satisfy the RFID system requirement of anti-collision algorithm, which improves the stability of system.关键词
