A Passive RFID Location Sensing
نویسنده
چکیده
This paper proposes a location sensing model based on passive RFID systems. The proposed model is useful for identifying the location of moving nodes relative to existing anchor nodes, i.e. nodes with known coordinates, which has applications in logistics, yard and warehouse management. The study explores algorithms for estimating location coordinates. These algorithms are much simpler to implement than other techniques such as signal attenuation that have been suggested by others. The proposed model doesn’t require special hardware and control software that is needed by other approaches. It only requires basic passive RFID readers and tags. The study also demonstrates the implementation of a prototype in a laboratory environment along with the experimental results.

Effect of Reading Errors on Location Prediction in RFID Indoor Networks
In this Letter, we investigate the correlation rate of a random sequence data set which is collected by RFID (Radio Frequency IDentification) readers in an indoor location. Using a passive RFID tag introduces reading error, which causes a loss of original data. From the question of how sensing errors of RFID readers affect the location prediction algorithm used for context awareness services at...
