Abstract

The dynamic frame slotted ALOHA tag anti-collision Q algorithm in the EPCglobal_Class1 Gen2 protocol fails to remove empty slots, which leads to a waste of the slots. This is unacceptable in blood management which requires real-time handling and a large number of tags. A multi-tag identification and collision avoidance method was developed that divides the tag identification into two slot pre-assignments and tag identification. This helps eliminate empty slots in the Class1 Gen2 protocol which improves availability. Simulations of a blood management system indicate that this method significantly improves tag identification efficiency.
