On unequal missing protection of the grouping of RFID tags

In this paper, we address the issue of unequal missing protection (UMP) for the design of grouping of radio-frequency identification (RFID) tags. While relying on group generation matrices, grouping of RFID tags allows verifying the integrity of a collection of RFID tags without the requirement for accessing external systems, and can be extended to identify missing RFID tags. Motivated by application needs that call for UMP among RFID tags, we first introduce the concepts of UMP for grouping of RFID tags and its extended counterpart. We then present a simple scheme to realize extended grouping of RFID tags with UMP. Simulation results are presented to demonstrate the efficiencies of the proposed UMP scheme for extended grouping of RFID tags.
