基于RFID的室内定位算法改进
基于RFID的室内定位算法改进(论文9000字,外文翻译,参考代码)
摘要:本文通过介绍最具有代表性的两种基于RFID的室内定位算法(RSSI线性定位算法、LANDMARC算法)的原理,详细比较两种算法在精度和运算量上的优缺和适用环境,结合两种算法特点,在非边缘区域使用LANDMARC算法,在边缘区域使用RSSI算法,提出了一种RFID室内定位的改进算法,改进后的算法更精确并大大减少算法的运算量。同时进行大量的Matlab仿真运算,验证改进后的算法基本满足设定的要求,定位误差较RSSI算法减小了54.7%,系统定位耗时较LANDMARC算法减少了43.1%。

Improved indoor location algorithm based on RFID
Abstract:In this paper, first introduces two kinds of existing indoor positioning algorithm based on RFID RSSI linear positioning algorithm and LANDMARC algorithm, analyzes its advantages and disadvantages, through the combination of the two algorithms of RFID indoor positioning algorithm is improved, the improved algorithm is more accurate and greatly reduce the computational complexity of the algorithm.Through a large number of simulation operations, the improved algorithm basically meets the requirements set, compared to the original two algorithms in the accuracy and reduce the amount of calculation to achieve the desired objectives.The positioning error is reduced by 54.7% compared with the RSSI algorithm, and the location time of the system is reduced by 43.1% compared with the LANDMARC algorithm.
Keywords:RFID,indoor location algorithm,RSSI ,LANDMARC ,Matlab
