Les protocoles MAC pilotés par CSMA/CA retiennent les transmissions de paquets des stations exposées lorsqu'ils détectent un signal porteur au-dessus d'un certain seuil. Ceci afin d'éviter les collisions avec d'autres stations de réception. Cependant, ce schéma conservateur expose souvent inutilement de nombreuses stations et minimise ainsi l’utilisation de la ressource spectrale spatiale. Dans cet article, nous démontrons que l'estimation à distance de l'état des récepteurs actifs est plus efficace pour éviter les collisions dans les réseaux sans fil que la détection de porteuse. Nous appliquons un nouveau concept de plage d'interférence, nommé n-portée d'interférence tolérante, pour garantir des communications fiables en présence de n (n≥ 0) transmissions simultanées depuis l'extérieur de la plage. Nous concevons un distribué prévention des interférences MAC ( IP-MAC ) en utilisant le n-plage d'interférence tolérante qui permet des accès parallèles depuis les stations non interférentes pour une communication active. Dans IP-MAC, une station exposée passe par un contrôle de potentiel d'interférence (IPC) pour déterminer si elle interfère ou non avec la communication active. Pendant l'opération de résolution, IPC prend en compte l'effet de capture au niveau d'un récepteur actif avec les signaux interférents provenant d'un certain nombre de transmissions simultanées possibles à proximité de ce récepteur. L'amélioration des performances offerte par IP-MAC est étudiée via des simulations dans différents environnements. Les résultats révèlent qu'IP-MAC améliore considérablement les performances du réseau en termes de débit et de délai.

Abstract: The CSMA/CA driven MAC protocols withhold packet transmissions from exposed stations when they detect carrier signal above a certain threshold. This is to avoid collisions at other receiving stations. However, this conservative scheme often exposes many stations unnecessarily, and thus minimizes the utilization of the spatial spectral resource. In this paper, we demonstrate that remote estimation of the status at the active receivers is more effective at avoiding collisions in wireless networks than the carrier sensing. We apply a new concept of the interference range, named as n-tolerant interference range, to guarantee reliable communications in the presence of n (n≥ 0) concurrent transmissions from outside the range. We design a distributed interference preventive MAC ( IP-MAC ) using the n-tolerant interference range that enables parallel accesses from the noninterfering stations for an active communication. In IP-MAC, an exposed station goes through an Interference Potentiality Check (IPC) to resolve whether it is potentially interfering or noninterfering to the active communication. During the resolve operation, IPC takes the capture effect at an active receiver into account with interfering signals from a number of possible concurrent transmissions near that receiver. The performance enhancement offered by IP-MAC is studied via simulations in different environments. Results reveal that IP-MAC significantly improves network performance in terms of throughput and delay.
