Installation and Evaluation of RFID Readers on Moving Vehicles

| Abstract |

|
Due to recent technology advancements, RFID readers have
been proposed for several vehicular applications ranging from
safe navigation to intelligent transport. However, one ob-
stacle to deployment is the unpredictable read performance.
An RFID reader occasionally fails to read an RFID tag even
in static circumstances, mostly due to collisions. In a mo-
bile vehicular environment, latency becomes the key perfor-
mance factor because of the high speed of vehicles. This is
particularly true when the RFID reader is on the moving
vehicle. In this paper, we investigate RFID read latency
and thus e®ectiveness of on-vehicles reader installations for
a wide range of speeds. First, we experimentally study the
impact of reader and tag relative positions on read errors and
read rates. Then we conduct road experiments at varying
speeds. The results reveal the critical factors that in°uence
on-vehicle RFID read performance, and give us guidance to
identify and pursue directions for improvement.
