Abstract: Systems and methods for computing and/or utilizing mutual information based link metrics for a link in a wireless mesh network are disclosed. In one embodiment, one or more mutual information values are computed for a link between a transmitter of a first network node and a receiver of a second network node in a wireless mesh network. Each of the one or more mutual information values is computed for a different hypothesized transmission mode for the link. One or more link metrics for the link are computed as a function of the mutual information values, where each link metric is computed based on a different one of the one or more mutual information values. In this manner, a link metric is computed for each of the one or more hypothesized transmission modes for the link. At least one of the link metrics are then provided to a routing update module.

Abstract: Systems and methods for link adaptation for a multi-hop route in a wireless mesh network are disclosed. In one embodiment, a wireless mesh network includes network nodes in a route through the wireless mesh network. The network nodes determine a bottleneck information flow rate for the route based on backward propagation of information indicative of a tentative bottleneck information flow rate for the route from an ending network node to a starting network node through one or more intermediate network nodes. A target information flow rate for the route that is less than or equal to the bottleneck information flow rate for the route is determined. A Modulation and Coding Scheme (MCS) and, in some embodiments, a transmission mode is determined for each network node in the route other than the ending network node based on forward propagation of information indicative of the target information flow rate for the route.
