Enhanced class 0 RFID anticollision protocol.

摘要

The concept put forth in this thesis proposes a modification to the existing anticollision protocol used for identification of Class 0 Radio Frequency identification (RFID) tags, to improve the read rate of tags. A comparison to the new (Generation 2) anticollision protocols has also been established.; The current protocol used for singulation of Class 0 RFID tags uses a binary tree based protocol that resets to the root of the tree upon recognition of every leaf (RFID tag) in the tree. This fixes the amount of time taken for reading of a group of tags.; If in the above protocol, the algorithm resets to an intermediate node in the tree instead of the root every time, a significant improvement in the read rate of a group of tags can be observed.; The new Generation 2 anticollision protocols proposed by EPCglobal Inc, are more robust than the previous protocols. This comes at the cost of time and complexity as pointed out in this paper.
