Survivable millimeter-wave mesh networks

Adaptive wireless mesh networks: Surviving weather without sensing it

“…The effective BER of the link is, in turn, a function of the received signal strength. This type of method has been suggested earlier in [6]. Our rainstorm model is different from [6] though, as we use contour-based boundaries for different radar reflectivity areas, as explained further later, whereas they use ellipses to bound such areas in their simulations.…”

“…For our work described in this paper, we use Bit Error Rate (BER) of a link as the measure of link quality. Such a cross-layered OSPF protocol was presented earlier in [6].…”

“…The work in [6] presents a predictive routing protocol for millimeter-wave wireless mesh networks (MWMNs), but the prediction in that work is done on information external to the network. There, weather predictions, assumed to be available through a weather radar covering the same area as the MWMNs to one or more core nodes in the network, are used to calculate link qualities using the Crane model [7] or the ITU-R model [8].…”

A survey on network resiliency methodologies against weather-based disruptions

“…Unlike the proposal from [19] and [20], two other techniques (called XL-OSPF and P-WARP [22], [21]) to improve performance of WMNs under weather-based disruptions rely on further enhancements of routing algorithms. In particular, routing in XL-OSPF is done based on a link-cost metric proportional to the observed bit error rate (BER) of WMN links.…”

“…• The second is to introduce rain-related link states to improve the routing mechanism [21], [18]. The rainrelated link state can be either adjusted according to locally measured data (for example Bit Error Rate) or from externally measured information (e.g., radar data).…”
