Current deployment of wireless community mesh networks and wireless municipal services using mesh connectivity utilizes single channel backbone mesh network to provide Internet connectivity to end users. IEEE 802.11s Wireless Mesh Network (WMN) is a promising technology to increase spatial reuse in a single channel mesh backbone using high gain directional antennas. However, for effective use of multi-interface multi-beam directional antennas in single channel environment, proper scheduling of interfaces and prioritization among different beams are required to minimize channel interference. Furthermore, the packet forwarding mechanism should co-operate with scheduling mechanism to improve network performance. This report provides current state of art for MAC layer channel access in single channel wireless mesh networks. It further discusses the motivation of using single channel directional antenna based communication in wireless mesh backbone for community and municipal wireless usage. The requirement of an efficient scheduling mechanism on the top of IEEE 802.11s standard is discussed with examples. Finally, the report provides the detail design and analysis for first contribution of the current research work - an efficient channel access and forwarding mechanism in IEEE 802.11s single channel directional wireless mesh network with single class traffic.
