摘  要:标签冲突对RFID系统的性能有负面影响。在本文中,我们提出了一种基于改进的碰撞检测算法,称为防碰撞协议(ACP-ICD)。该协议采用双前缀匹配和碰撞位检测技术,减少查询次数,快速识别标签。根据碰撞仲裁过程中的双前缀匹配方法和碰撞位检测,消除了空闲时隙,提高识别效率。分析和仿真结果表明,ACP-ICD性能优于现有的防碰撞算法。

An Efficient TagRecognition Algorithm Based on Iimproved Collision Detection

YAN Yaning

Abstract:Tag collisions have a negative impact on the performanceof RFID systems.In this paper,we propose an improvedcollision detection algorithm called anti-collision protocol (ACP-ICD).Theprotocol uses double prefix matching and collision bit detection techniques toreduce the number of queries and rapidly identify tags. According to the doubleprefix matching method and collision bit detection in collision arbitration,the idle time slot is eliminated and the recognition efficiency isimproved. Analysis and simulation results show that ACP-ICD performs betterthan existing anti-collision algorithms.
