“…After a guard period without transmissions in both channels, the reader occupies the control channel filling it with beacons, and shortly afterwards it starts the tag reading process. In [13] a similar mechanism is suggested, but only for minimizing RRI, whereas [6] introduces another LBT aimed at RTI minimization. In the latter, a wireless sensor network is selected for reader-to-reader communications, but this network is not use for sensing any particular parameter, thus resulting in higher costs.…”

In realistic deployments, several readers may be placed in the same area, forming a, so-called, dense reader environment. These scenarios are susceptible to suffer Reader Collision Problems, characterized by Reader-to-Tag and Reader-to-Reader interferences. Both affect network throughput, decreasing the overall number of tags identified per reader. This paper reviews the mechanisms proposed to mitigate the Reader Collision Problems. Besides, the constraints of these techniques are pointed out. The mechanisms have been evaluated to study the efficiency of the resources allocation.

In this paper, an anti-collision protocol called code division cooperative identification protocol (CDCIP) is proposed in order to tackle the reader collision problem in smart RFID systems. CDCIP allocates orthogonal sequences to each reader and composes a RFID network. Consequently, it strives to let more than one reader work at the same time and at the same frequency. Eventually, comparing with the traditional protocol, the simulation results show that the proposed protocol offers better average throughput and lower power consumption of the system.

“…The degree of interference measured at each reader is used as a local feedback parameter to dynamically adjust its transmission power. In [14] a similar mechanism is suggested, but only for minimizing readerto-reader collisions, whereas [15] introduces another LBT aimed at reader-to-tag collision minimization. In the latter, a wireless sensor network is selected for reader-to-reader communications.…”

Abstract-In this paper we solve analytically the problem of distributing optimally a set of t slots between a group of n readers in RFID dense environments where a single frequency channel is available. In these environments, the readers within reader-to-reader interference range must transmit at different times, otherwise tags cannot identified. This resource allocation problem is addressed for both static and dynamic Frame Slotted Aloha, which are the most broadly extended mechanism used in UHF RFID systems. The goal is maximizing the expected number of tags successfully identified within the t slots. Results demonstrate that the optimal solution outperforms an assignment proportional to the number of tags in each reader. The results heavily depend on the underlying reading algorithm of the reader.
