The RFID reader-to-reader collision is a well-known interference problem that affects large RFID systems with many readers. In recent years, several anti-collision protocols have been proposed in order to address this problem. However, the evaluation of these approaches is often based on simple models that consider only direct collisions among two readers. Instead, more complex models capture the total signal power emitted by each reader and assume that the power of each signal decays as distance grows. In this paper, the main models of the two families are described, and a comparison is presented, in order to investigate their effectiveness for the study and the evaluation of reader-to-reader collision.
