Performance of BFSA collision resolution: RFID including non-unique tag IDs
As RFID technology becomes ever more affordable, its large scale implementation has been a growing trend in recent years. While current protocols allow for non-unique tag IDs, most existing implementations largely optimize RFID system’s performance based on the assumption of unique tag IDs and treat the existence of non-unique tag IDs within reader’s range as a rare occurrence. Nevertheless, unless formally evaluated, it is not clear, what is the degree of performance degradation in the presence of non-unique tag IDs .We evaluate the behavior of Basic Frame Slotted ALOHA (BFSA) collision resolution for an RFID system using OPNET Modeler 14.5 as both simulation, as well as, analytical results visualization platform. The system is built assuming muting of tags by the reader and contains a mix of unique and non-unique tag IDs. Our findings are compared with results obtained from the evaluation of a similar model for a system consisting solely of unique tag IDs . The comparison of total census delay and throughput under variable frame sizes showed an increase in total census delay with an increase in number of tags and a decrease in network throughput with increase in the number of tags for the system allowing non-unique IDs.
