Research on Missing Tag Iceberg Query for Multi-Category RFID Systems With Non-Ideal Channel

摘要

Large-scale multi-category RFID system can be widely applied in many applications, such as localization, inventory management and smart logistics, etc. Missing tag iceberg query is one of the key techniques in the above application scenarios. Based on the existing missing tag iceberg query scheme called MAC-SSZE, this paper propose a novel missing tag iceberg query scheme, which adopts the signal integrity check method ECC to solve the problem of transmission error with the non-ideal communication channel. The proposed missing tag iceberg query scheme is based on the framed slotted Aloha protocol, and is able to conduct the self-correction by adding the check data into the broadcasted segments. The simulation results illustrate that the missing tag iceberg query scheme can achieve satisfied performance when there exists transmission error.
