RFID定位系统中内存点位置信息传输算法
当前的RFID定位系统往往以固定式集中式基础设施为基础进行位置估计,系统的延时较大、可扩展性有限,往往难以应用在物联网大规模动态场景中。为此,提出一种内存点的位置信息传输算法。首先,各个异构非协调性移动RFID阅读器通过间接合作对移动或固定式RFID贴标对象进行定位,然后利用已知智能环境中的可用内存点来传输位置信息,最后移动RFID利用这些内存点来存储标签位置和实现检索,使得RFID互相之间不进行直接通信就可以交换位置信息。基于ns-3的全面仿真实验结果表明,在多种环境配置下,本文算法的定位延时和平均开销均优于典型的拉引式传输算法。...

Bibliography: | YE Zhi-xiang1, ZHANG Wei-le2 (1.The Economics and Management College, Guangdong Institute of Science and Technology, Zhuhai 519090, China; 2. The Ministry of Education Key Laboratory of Intelligent Networks and Network Security, Xi' an Jiaotong University, Xi' an 710049, China) The existing RFID localization system is based on the centralized and fixed infrastructure which provides limited scalability and may not be plausible in typical Io T large-scale dynamic scenarios. To solve this problem,a distributed location information transmission algorithm based on memory spots is proposed in this paper. Firstly,heterogeneous uncoordinated mobile RFID readers localize the mobile or stationary passive RFID tagged-objects through indirect cooperation,and then the location information is disseminated by using the available memory spots in a given smart environment. Finally,mobile RFID readers use such memory spots to store tag locations and queries enabling exchange location information without the need for direct comm |
