Dans le présent article, l'utilisation d'une combinaison de techniques de liaison de canaux et de techniques multicanaux est proposée pour améliorer les performances des réseaux maillés sans fil (WMN). Il est nécessaire d'augmenter le débit du réseau en élargissant la bande passante, et deux approches pour utiliser efficacement la bande passante élargie peuvent être envisagées. La première est la technique multicanal, dans laquelle plusieurs canaux de fréquence distincts sont utilisés simultanément pour la transmission d’informations. L'autre est la technique de liaison de canaux utilisée dans la norme IEEE 802.11n, qui relie plusieurs canaux de fréquence en un seul canal plus large. Le premier peut réduire le trafic du canal pour atténuer l'effet de collision de paquets, tandis que le second peut augmenter le taux de transmission. Dans le présent article, ces deux approches sont comparées et leurs avantages respectifs sont clarifiés en termes de débit du réseau et de performances de retard en supposant la même bande passante totale et un protocole CSMA. Nos résultats numériques et de simulation indiquent que dans des conditions de faible trafic, la technique de liaison de canaux peut atteindre un faible délai, tandis que dans des conditions de congestion du trafic, les performances du réseau peuvent être améliorées en utilisant une technique multicanal. Sur la base de ce résultat, l'utilisation d'une combinaison de ces deux techniques est proposée pour un WMN, et montre qu'il est préférable d'utiliser une technique de canal appropriée en fonction des conditions de trafic du réseau. Les résultats de la présente étude contribuent également à améliorer les performances d'un réseau multimédia, composé de différents types de trafic d'applications.

Abstract: In the present paper, the use of a combination of channel-bonding and multi-channel techniques is proposed to improve the performance of wireless mesh networks (WMNs). It is necessary to increase the network throughput by broadening the bandwidth, and two approaches to effectively utilize the broadened bandwidth can be considered. One is the multi-channel technique, in which multiple separate frequency channels are used simultaneously for information transmission. The other is the channel-bonding technique used in IEEE 802.11n, which joins multiple frequency channels into a single broader channel. The former can reduce the channel traffic to mitigate the effect of packet collision, while the latter can increase the transmission rate. In the present paper, these two approaches are compared and their respective advantages are clarified in terms of the network throughput and delay performance assuming the same total bandwidth and a CSMA protocol. Our numerical and simulation results indicate that under low-traffic conditions, the channel-bonding technique can achieve low delay, while under traffic congestion conditions, the network performance can be improved by using multi-channel technique. Based on this result, the use of a combination of these two techniques is proposed for a WMN, and show that it is better to use a proper channel technique according to the network traffic condition. The findings of the present study also contribute to improving the performance of a multimedia network, which consists of different traffic types of applications.
