Abstract In RFID (Radio Frequency IDentification) system, when multiple tags
are in the operating range of one reader and send their information to the reader
simultaneously, the signals of these tags are superimposed in the air, which results
in a collision and leads to the degrading of tags identifying efficiency. To improve
the multiple tags’ identifying efficiency due to collision, a physical layer network
coding based binary search tree algorithm (PNBA) is proposed in this paper.
PNBA pushes the conflicting signal information of multiple tags into a stack,
which is discarded by the traditional anti-collision algorithm. In addition, physical
layer network… More >
