“…A wide different approach are proposed for channel allocation for multi radio and multi-channel allocation in the WMN literature. Our previous contribution [41] presents the detailed study of various algorithms of channel assignment under different classification schemes. Another study on channel assignment schemes for WMN is presented in [30].…”

Wireless Mesh Networks(WMNs) are the outstanding technology to facilitate wireless broadband Internet access to users. Routers in WMN have multiple radio interfaces to which multiple orthogonal/partially overlapping channels are assigned to improve the capacity of WMN. This paper is focused on channel selection problem in WMN since proper channel selection to radio interfaces of mesh router increases the performance of WMN. To access the Internet through WMN, the users have to associate with one of the mesh routers. Since most of the Internet Servers are still in wired networks, the major dominant traffic of Internet users is in downlink direction i.e. from the gateway of WMN to user. This paper proposes a new method of channel selection to improve the user performance in downlink direction of Internet traffic. The method is scalable and completely distributed solution to the problem of channel selection in WMN. The simulation results indicate the significant improvement in user performance.

“…The proposed algorithm can be formulated using a mathematical LP problem and they showed that it was very effective for load balancing compared to the simple adoption of IEEE 802.11s (a standard TDMA protocol in WMNs). Other researchers in [24] proposed a new method of channel selection in multi-radio multi-channel WMNs to improve the user performance in downlink direction of Internet traffic. However, the cross-layer method used in the literature [12][13][14][15][16][17], [25] and [26] does not consider the development of IEEE 802.11n/ac MAC and PHY in determining the choice of data rate, nor the best route to produce optimal throughput in IEEE 802.11s WMNs.…”

The wireless mesh network (WMN) is a future network technology that develops single-hop wireless local area networks (WLANs) into multi-hop wireless mesh networks, based on the IEEE 802.11s standard. However, this development still presents many challenges, such as determining the best route between sources and destinations, especially taking into account the use of the medium access control (MAC) and physical (PHY) layers of IEEE 802.11n/ac. Some papers have proposed rate adaptation algorithms particularly for single-hop networks; however, these only focused on mechanisms to find data rates suitable for channel conditions. In IEEE 802.11s WMNs, the design of the rate adaptation algorithm is more challenging. Besides considering the problem of channel quality and optimal throughput, it is necessary to also consider the problem of collision and the best route. It is important to take collision into account because the collision probability in multi-hop mesh networks is higher than that in single-hop networks and can lead to a lower throughput. Rate adaptation algorithms for IEEE 802.11s WMNs have been proposed in other papers, but they also do not consider the use of the MAC and PHY layers of IEEE 802.11n/ac. In this paper, we propose the collision-aware rate adaptation for optimal high-throughput (CARA-OHT) algorithm for WMN IEEE 802.11s. An evaluation through the extensive use of a network NS-3 simulator shows that the proposed algorithm exhibits a higher throughput than previously developed algorithms.

IEEE 802.11 Wireless Mesh Networks are used widely in commercial and civilian applications. Most importantly, wireless mesh networks are used as last-mile broadband Internet access technology so that user can experience wireless broadband high-speed Internet connectivity. Usually, a router in wireless mesh network has at least two radio interfaces: access interface and routing interface. As the radio spectrum has limited number of orthogonal channels, the two radio interfaces must be assigned with channels having low interference and maximal non-overlapping frequency to improve the network performance. This paper proposes a new scheme of channel allocation based on fuzzy logic for wireless mesh networks. A mesh router uses four parameters: channel access delay, signal to interference ratio, link bandwidth and hop count from gateway node to rate the channels and the router selects a best channel in improving the user quality access. Through the simulation results, it is observed that the proposed scheme is scalable and has a significant performance.
