A Data-Driven Approach to Disaster Resilience in Communication Networks

Communication networks are critical in business, government, and even our day-to-day life. A prolonged communication outage can have devastating effects, particularly during and after a disaster. Unfortunately, our communication infrastructure is still vulnerable to natural disasters and other events that damage multiple network components...

Identifying critical and vulnerable links: A new approach using the Fisher information matrix

In traffic networks, some elements are more prone to suffer or to create disruptive situations, and the identification of these elements becomes a challenge due to the large number of possible threats. The following paper presents two new methodologies to identify and rank vulnerable and critical links of traffic networks. These methodologies...

The Risk of Successive Disasters: A Blow-by-Blow Network Vulnerability Analysis

It is often assumed that a network will not be struck by multiple disasters in a relatively short period of time; that is, a subsequent disaster will not strike within the recovery phase of a previous disaster. However, recent events have shown that combinations of disasters are not implausible. This realization calls for a new perspective on...

Pattern Recognition for Reliability Assessment of Water Distribution Networks

The study presented in this manuscript investigates the patterns that describe reliability of water distribution networks focusing to the node connectivity, energy balance, and economics of construction, operation and maintenance. A number of measures to evaluate the network resilience has been developed and assessed to arrive at more accurate...
