Abstract: | RFID technology has enabled great advances in the asset tracking industry. Shipping, warehouse inventory, and storefront security are just a few examples where the application of RFID systems has increased efficiency and lowered cost. A major area of research at the present time is concerned with optimal ways of reading multiple ID tags using 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 tags and 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, therefore reading one ID tag at a time. This thesis seeks to present another, novel approach to solving the same problem. The proposed method seeks not to avoid collisions, but rather to orchestrate them in a manner that allows overlapping transmission of the ID tags while identifying all of the ID tags that take part in the transmission. This method will provide a highly time-efficient collision management protocol. |
