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.

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.
