“…needed for resilience " (20). This perspective highlighting the positive impacts of higher connectedness comes largely from the engineering concepts of robustness and redundancy (Pavard et al, 2008;Krupa et al, 2014), and are frequently invoked when discussing designed networks or engineered systems (Sterbenz et al, 2014). From this perspective, if one node or set of nodes in a network fails, higher connectivity increases the likelihood that compensating pathways through the network will exist.…”

Quantifying urban economic resilience through labour force interdependence

Resilience is increasing rapidly as a framework to understand and manage coupled human-natural systems. Yet the concept of resilience is rarely quantified. Here we quantify system resilience by operationalizing the notion of system tightness. Multiple resilience frameworks recognize the strong relationship between system tightness and resilience, though they differ on the directionality of that relationship. Thus, by measuring the system tightness we ultimately measure urban economic resilience, with the added benefit of empirically determining the directionality of the relationship between tightness and resilience. We then assess how well this measure predicts the response of urban economies to the recent so-called Great Recession. Results show that cities with lower tightness (higher resilience) fared better during the recession with respect to several economic productivity measures. However, in the absence of shocks, those with higher tightness (lower resilience) exhibit superior economic performance. Thus, a tradeoff between efficiency and resilience is nicely reflected in the empirical data. Although this study deals with economic shocks, quantitative metrics based on its methodology may help anticipate a city's response to shocks more generally, such as natural disasters, climate change, social unrest or significant policy shifts.

In this position paper on reliable networks, we discuss new trends in the design of reliable communication systems. We focus on a wide range of research directions including protection against software failures as well as failures of communication systems equipment. In particular, we outline future research trends in software failure mitigation, reliability of wireless communications, robust optimization and network design, multilevel and multirealm network resilience, multiple criteria routing approaches in multilayer networks, resilience options of the fixed IP backbone network in the interplay with the optical layer survivability, reliability of cloud computing networks, and

“…Papers on region failures available in the literature are dedicated mainly to wired networks [16][17][18][19][20] with special focus on optical WDM networks protection (e.g., [16,17,21,22]). Among few proposals concerning reliability of transmission in wireless networks, we can mention works related to routing issues addressing shared medium problems, or nodes mobility [23].…”

Wireless Mesh Networks, offering transmission rates of 1-10 Gb/s per a millimeter-wave link (utilizing the 71-86 GHz band) seem to be a promising alternative to fiber optic backbone metropolitan area networks because of significantly lower costs of deployment and maintenance. However, despite providing high transmission rates in good weather conditions, high-frequency wireless links are very susceptible to weather disruptions. In particular, heavy rain storms may lead to remarkable signal attenuation. In this paper, we introduce a new transmission technique for wireless mesh networks to mitigate the negative effects of link quality degradation due to rain storms. In particular, our method is the first one to use information on forecasted attenuation of links based on radar measurements to perform in advance the periodic updates of a network topology. Our approach is easily implementable in practice, since functionality of dynamic antenna alignment is currently offered by a number of equipment vendors. Other contributions of the paper include presentation of the ILP model of weatherresistant links formation problem followed by analysis of its computational complexity. Results of simulations, performed for three real scenarios of rain storms, show that our approach is very efficient in reducing the level of signal attenuation.
