“…The experimental result shows that the read range of a handheld reader with EIRP 17dbm (PA output power : 14dbm, antenna gain : 3dbi) is extended from 70 cm to 6.3m with the BoMR [1]. While [1] focused on the performances of a single BoMR, those of UMRR under multiple BoMRs are investigated in this paper. We discarded the arbitration function in the BoMR since it is not appropriate to the multiple BoMR environments due to the collisions between BoMRs.…”

Form factor and demand for low power consumption limit the transmission power of UHF mobile RFID readers. BoMR [1], a kind of booster for mobile RFID readers to extend the read range, was introduced and its performance was analyzed. But some practical issues such as collision and interference should be estimated for its widespread usage. In this paper, the collision, interference and performance of BoMRs are evaluated under multiple BoMR environments. Simulation model with DEVS formalism is presented and the results are summarized. Finally, the performances of LBT schemes are studied by simulation.

“…However its short read range caused by form factor problem, low-gain antenna and low-power transmission limits application. We developed a booster for Mobile RFID readers (BoMR) to overcome the deficits of UMRR and extend the read range [1]. BoMR amplifies the RFID reader signal(①) including a continuous wave(CW).…”

-The read range of UHF mobile readers can be extended by a booster for mobile RFID readers (BoMR). But in an environment where multiple BoMRs are installed, the read success rate may be decreased due to signal interference. This paper proposes three arbitration methods based on interference estimation with the purpose of enhancing the read success rate. A central arbitration server manages global information in centralized arbitration method (CAM) without broadcast/multicast communication facility. In fully distributed arbitration method (FDAM), all the arbitration messages are broadcasted from a BoMR to every BoMR, and each BoMR decides with broadcasted global information. Events in FDAM are serialized naturally with broadcasted messages. Cluster Distributed Arbitration Method (CDAM) forms clusters with multicasted BoMRs and a selected BoMR acts as an arbiter in the cluster. Such effects as lengthened read range, improved the read success rates of readers can be obtained by the proposed methods without any hardware modification. In order to evaluate the arbitration methods, the RFID system is modeled by using the DEVS formalism and simulated by using the DEVSim++.
