Indoor and outdoor position identification using RFID

Abstract

Radio Frequency Identification (or RFID) tags has found a wide range of applications in the modern world with a promising future. Tourism directly affects a country's income. In this paper we have proposed a system which uses RFID tags for guidance of tourists. In the proposed system RFID tags are used to guide and to inform the tourists about the given location and surrounding. Tourists usually prefer guided tourism in order to get genuine information about the places of interest. The system presented in our paper provides the audio based tourist guidance information which a tourist prefers providing the relevant information about the spots. We have presented an algorithm which describes the deployment of the system even for densely populated RFID based geographic regions. The system collaborates with multiple readers while reading the RFID tag data. We have considered the cases where tag ID is used for sensing the environmental conditions and parameters and for identification purpose. The system has been tested with Adaptive Binary Splitting Scheme (ABS) for avoiding clash of tags and an adaptive synchronization algorithm, a novel technique for avoiding reader interference in a region. Also performance issues have been addressed related to efficiency in similar systems by exploiting redundancy.
