Cet article propose un nouveau schéma de contrôle d'accès avec détection de collision qui utilise la technologie MIMO (Multiple-Input Multiple-Output). L'accès multiple à détection de porteuse avec détection de collision (CSMA/CD) est utilisé dans les réseaux locaux (LAN) câblés Ethernet pour le contrôle d'accès aux médias (MAC). CSMA/CD peut immédiatement interrompre une transmission si une collision est détectée et est ainsi capable de passer à un état de retransmission. En Ethernet, CSMA/CD entraîne une efficacité de transmission d'environ 90 % car le protocole rend la bande de transmission disponible pour une communication utile par cette fonction de retransmission. À l’inverse, dans les réseaux locaux sans fil (WLAN) conventionnels, les collisions de paquets dues aux signaux interférents et la retransmission due aux collisions constituent des problèmes importants. Étant donné que les WLAN conventionnels ne peuvent pas détecter les collisions de paquets pendant la transmission du signal, le succès d'une transmission ne peut être déterminé que par la réception ou non d'une trame d'accusé de réception (ACK). Par conséquent, l’efficacité de la transmission est faible – environ 60 %. L'objectif de notre étude est d'augmenter l'efficacité de transmission des WLAN pour la rendre au moins égale à celle d'Ethernet. Ainsi, nous proposons un nouveau schéma de contrôle d’accès avec détection de collision qui utilise la technologie MIMO. Lorsque les signaux de préambule sont transmis avant la transmission des paquets de données depuis une antenne, le système proposé peut détecter les collisions de paquets pendant la transmission du signal au niveau d'une autre antenne ; ensuite, les paquets concernés sont retransmis immédiatement. Deux technologies fondamentales sont utilisées pour réaliser notre schéma proposé. La première technologie est le protocole de contrôle d'accès dans la couche MAC sous la forme du protocole de séquence de trames MIMO, utilisé pour détecter les interférences de signal. L’autre technologie est le traitement du signal dans la couche physique (PHY) qui actualise la détection des collisions. Cet article traite principalement du schéma de couches MAC proposé, qui est évalué par des analyses théoriques et des simulations informatiques. L'évaluation par simulations informatiques indique que le schéma proposé a une efficacité de transmission supérieure à 90 %.

Abstract: This paper proposes a novel access control scheme with collision detection that utilizes multiple-input multiple-output (MIMO) technology. Carrier sense multiple access with collision detection (CSMA/CD) is used in Ethernet wired local area networks (LANs) for media access control (MAC). CSMA/CD can immediately abort a transmission if any collision is detected and is thus able to change to a retransmission state. In Ethernet, CSMA/CD results in a transmission efficiency of approximately 90% because the protocol makes the transmission band available for useful communication by this retransmission function. Conversely, in conventional wireless LANs (WLANs), the packet collisions due to interfering signals and the retransmission due to collisions are significant issues. Because conventional WLANs cannot detect packet collisions during signal transmission, the success of a transmission can only be determined by whether an acknowledgment (ACK) frame has been received. Consequently, the transmission efficiency is low — approximately 60%. The objective of our study is to increase the transmission efficiency of WLANs to make it at least equal to that of Ethernet. Thus, we propose a novel access control scheme with collision detection that utilizes MIMO technology. When preamble signals are transmitted before transmitting data packets from an antenna, the proposed scheme can detect packet collisions during signal transmission at another antenna; then, the affected packets are retransmitted immediately. Two fundamental technologies are utilized to realize our proposed scheme. The first technology is the access control protocol in the MAC layer in the form of the MIMO frame sequence protocol, which is used to detect signal interference. The other technology is signal processing in the physical (PHY) layer that actualizes collision detection. This paper primarily deals with the proposed MAC layer scheme, which is evaluated by theoretical analyses and computer simulations. Evaluation by computer simulations indicate that the proposed scheme in a transmission efficiency of over 90%.
