Framed Aloha Based Anti-collision Protocol for RFID tags

In this paper, we present evaluation performances of an anti-collision protocol for RFID tags. The protocol enables electronic markers, also known as smart labels or tags, to be identified. The principle of the protocol is the framed aloha with an optimization of the frame length. The optimization of this length is based on an evaluation of the number of active tags. Besides its performances, a particularly interesting feature of the method is that it does not depend on factory parameters or uniqueness of the identifier and that it adapts itself to environmental conditions to ensure efficient identification.
