Quality-Driven Schemes Enhancing Resilience of Wireless Networks under Weather Disruptions

Heavy rain, dense fog, snow, extreme temperatures and moving objects represent a few examples of environmental conditions, which have a significant influence on reliable communications over wireless networks. In particular, a wireless link is vulnerable to precipitation or to fluctuations caused by reflections of signals from moving objects. Wireless signal can experience the so-called path loss or attenuation of signal strength. In this case, critical environmental changes in communication and its degradation are noticeable by users as well as network operators while service and network quality are evaluated by them, respectively. A dependence of the overall quality of communications on different quality parameters can be used as a suitable tool for effective resilience of wireless communications against the environmental disruptions. This chapter presents ideas about how the quality parameters from different communication layers can be used to create alerts when the performance of a service over wireless optical network is being degraded, as well as how data can be rerouted in a wireless sensor network, and a wireless positioning system can be modified in the presence of environmental disruptions.
