"Towards an Energy Efficient Protocol for Active RFID"
Paper in proceedings, 2006
The use of Radio Frequency Identification systems
(RFID) is growing rapidly. Today, mostly Passive
RFID systems are used because no onboard energy
source is needed on the transponders. However,
Active RFID with onboard power source gives a new
range of opportunities not possible by passive systems.
To obtain energy efficiency in an active RFID system a
protocol should be designed that is optimized with
energy in mind. This paper describes the on-going work
of defining and evaluating such a protocol. The
protocols performance in terms of energy efficiency,
aggregated throughput, delay, and number of air
collisions is evaluated and compared to that of the
medium-access layer in 802.15.4 Zigbee, and also to a
commercially available protocol from Free2move.
and an optimal protocol.
