Investigation of Interference Models for RFID Systems

The reader-to-reader collision in an RFID system is a challenging problem for communications technology.In order to model the interference between RFID readers, different interference models here have been proposed, mainly based on two approaches: single and additive interference.The former only considers the interference from one reader within a certain range, whereas the latter takes into account the sum of all of the simultaneous interferences in order to emulate a more realistic behavior.Although the difference between the two approaches has been theoretically analyzed in previous research, their effects on the estimated performance of the reader-to-reader anti-collision protocols have not yet been investigated.In this paper, the influence read more of the interference model on the anti-collision protocols is studied by simulating a representative state-of-the-art protocol.

The results presented in this paper highlight that the use of additive models, although more computationally intensive, is mandatory to improve the performance of anti-collision protocols.
