Routing for Capacity Improvement in Multi-Channel-Width Multi-Radio Wireless Mesh Networks
In this paper, the authors indicate that the assignment of multiple channels with different bandwidths to links of an IEEE 802.11 wireless mesh network can drastically increase the capacity of these networks considering equal amount of available spectrum. However, this is possible only for networks where routers are equipped with multiple radios. This paper proposes a metric used to select the amount of radios and width of the channels to be used in each link, as well the routing path that enables a decrease in the interference between those links. They use simulations in Ns-2 to assess the proposed routing metric and compare it with others in the paper.
