Research On Indoor Positioning System Base On Radio Frequency Identification

In the indoor positioning, because in recent years the rapid development ofwireless network, there are many and indoor positioning related technology andapplication. Radio frequency identification (RFID) technology and non line-of-sightautomatic identification, short recognition and the characteristics of low cost to indoorpositioning research has very important significance, RFID technology through thecombination of the Internet and communication technology, and can realize a widerange of goods tracking identification and information sharing. Therefore, this paperfocuses on the radio frequency identification based on the indoor positioning systemalgorithm is studied, through the improvement of the algorithm, improving the indoorpositioning accuracy.This paper mainly studies the RFID indoor positioning system and its algorithm,the main work is as follows:1. Discussed RFID technology and its significance, and summarizes RadioFrequency Identification system the constitution principle.2. Further study the classic radio frequency identification indoor positioningsystem and the basic principle of RFID indoor positioning, etc.3. It advances based on the classical radio frequency identification indoorpositioning system Newton interpolation localization algorithm.4. Based on LARNDMARC system k neighborhood algorithm and Newtoninterpolation algorithm, and simulation analysis, the result of the comparison is given,and the conclusion.
