【 摘 要 】

RFID technology has enabled great advances in the asset tracking industry. Shipping,warehouse inventory, and storefront security are just a few examples where theapplication of RFID systems has increased efficiency and lowered cost. A major area ofresearch at the present time is concerned with optimal ways of reading multiple ID tagsusing a single reader as efficiently as possible. These methods are called “Anti-collision” protocols, and they all seek to somehow arbitrate how a multitude of ID tagsand a reader negotiate the process of reading all of the ID tags. As the name implies,nearly all of the methods seek to detect and avoid collisions between ID tags, thereforereading one ID tag at a time. This thesis seeks to present another, novel approach tosolving the same problem. The proposed method seeks not to avoid collisions, butrather to orchestrate them in a manner that allows overlapping transmission of the IDtags while identifying all of the ID tags that take part in the transmission. This methodwill provide a highly time-efficient collision management protocol.
