Resilience of Wireless Mesh Networks

This chapter presents a case study on resilient routing in Wireless Mesh Networks (WMNs) commonly formed by stationary mesh routers interconnected by wireless links. High-frequency communications (e.g., using the 71–86 GHz band) is the reason for the vulnerability of WMNs to weather-based disruptions, particularly to intensive precipitation. Therefore, heavy rainfalls may seriously reduce (or even completely degrade) the available link capacity in a given area. In this context, this chapter provides a set of measures of WMN resilience to region-based disruptions and proposes a transmission scheme that allows the preparation of the WMN topology to adverse weather conditions in advance by using the dynamic antenna alignment features according to forecasts of heavy rainfalls.
