Efficient Tag Grouping RFID Anti-Collision Algorithm for Internet of Things Applications Based on Improved K-Means Clustering
Dynamic Frame Slotted ALOHA (DFSA) is a de facto algorithm in the EPC Global Class-1 Generation-2 protocol for Radio Frequency Identification (RFID) tag collision problem.DFSA fails when the UHF RFID tag deployment becomes dense like in Internet of Things (IoT).Existing works do not provide readers prior tag estimates.Most algorithms assume a click
