Abstract
Today, municipalities are planning to deploy metroscale two-tier wireless mesh networks at a rapid pace. Fittingly, the IEEE 802.11s standard is being developed to allow interoperability between heterogeneous mesh network devices. In this article, we describe and discuss how the initial standard addresses key factors for standardization of these networks: (i) efficient allocation of mesh resources at the routing and MAC layers, (ii) protection and conservation of the network resources via security and energy efficiency, and (iii) assurance of fairness and elimination of spatial bias via mesh congestion control. We draw upon examples from existing two-tier deployments, simulations, and analytical models to motivate these enhancements within the standard.
