Research on RFID Collision Optimization Algorithms Based on ALOHA

Abstract

射频识别技术(RFID)凭借诸多性能上的优势,正在逐步成为零售业、库存管理、供应链管理应用的宠儿,受到前所未有的关注。RFID系统正在变得无处不在,在各行各业发挥着巨大的作用。RFID系统的运用首先必须要解决的问题便是标签识别过程中的碰撞问题,这一问题的存在影响着标签识别效率,也是RFID未来进一步发展亟需克服的阻碍。 基于ALOHA的防碰撞算法是当前解决碰撞问题的方法之一,此方法简单易行,在实际应用中表现突出。俘获效应作用下的RFID系统,如何准确地估算当前未识别地标签数量和该场景下地俘获效应大小是决定动态帧时隙ALOHA算法识别准确率的关键因素。设置最优的帧时隙大小以达到最优的识别效率取...So many great advantages that drive the growth of Radio Frequency Identification (RFID). Making RFID particularly attractive for applications in retail, inventory management, and supply-chain management. RFID systems are becoming Ubiquitous. one of the problems that we must solve is the collision between tags which lowers the efficiency of the RFID system. One of the popular anti-collision algor...学位:工学硕士院系专业:软件学院_软件工程学号:2432014115241
