Contrairement à l'identification par radiofréquence (RFID), la nouvelle RFID informatique (CRFID) intègre le frontal RF et le MCU avec plusieurs capteurs. Les CRFID doivent transmettre des données dans la portée de l'interrogateur. Ainsi, lorsque les étiquettes se déplacent rapidement ou que la durée du contact avec l'interrogateur est limitée, les données du capteur collectées par le CRFID doivent être transférées rapidement à l'interrogateur. Dans cet article, nous nous concentrons sur l'optimisation du débit pour la liaison de rétrodiffusion, prenons en compte les couches physique et de contrôle d'accès au support (MAC), et proposons notre schéma appelé ORRIS. Sur la couche physique, nous proposons l'indicateur Cluster Gather Degree (CGD), qui est le degré de regroupement du signal dans le domaine IQ. Ensuite, le CGD est considéré comme le critère permettant d'ajuster de manière adaptative le mode de codage du débit et la fréquence de liaison, afin d'obtenir en conséquence une transmission à débit adaptatif. Sur la couche MAC, sur la base de l'idée de transfert asynchrone, nous utilisons le nombre de clusters dans le domaine IQ pour sélectionner autant que possible la valeur Q optimale. Cela permet d'obtenir une transmission en rafale ou une transmission de données en masse. Les expériences et analyses sur les scénarios statiques et mobiles montrent que notre proposition a un débit moyen nettement meilleur que BLINK ou CARA, qui démontrent l'efficacité de notre système.

Abstract: Unlike Radio Frequency Identification (RFID), emerging Computational RFID (CRFID) integrates the RF front-end and MCU with multiple sensors. CRFIDs need to transmit data within the interrogator range, so when the tags moved rapidly or the contact duration with interrogator is limited, the sensor data collected by CRFID must be transferred to interrogator quickly. In this paper, we focus on throughput optimization for backscatter link, take physical and medium access control (MAC) layers both into consideration, put forward our scheme called ORRIS. On physical layer, we propose Cluster Gather Degree (CGD) indicator, which is the clustering degree of signal in IQ domain. Then CGD is regarded as the criterion to adaptively adjust the rate encoding mode and link frequency, accordingly achieve adaptive rate transmission. On MAC layer, based on the idea of asynchronous transfer, we utilize the the number of clusters in IQ domain to select the optimal Q value as much as possible. So that achieve burst transmission or bulk data transmission. Experiments and analyses on the static and mobile scenarios show that our proposal has significantly better mean throughput than BLINK or CARA, which demonstrate the effectiveness of our scheme.
