Risk-adaptive strategic network protection in disaster scenarios

Trade-offs between Risk and Operational Cost in SDN Failure Recovery Plan

“…Based on that model, the authors developed a predictive restoration plan that aimed to strike a balance between capacity optimization and the probability of service disruption. They further enhanced this method by taking network topological characteristics into account when calculating the risk and proposed adaptive and proactive risk management to protect network traffic in high-risk areas [11]. This approach is particularly suitable for SDN networks as it can be implemented at the SDN controller where information about the current failure rates and status of network elements can be stored and analyzed.…”

“…This problem highlights the need for proactive network protection approaches that would also be able to dynamically respond to network changes on the ground. For instance, a protection scheme that could evaluate and predict the risk of path failure and proactively reroute traffic from high-risk regions to low-risk regions could significantly reduce the number of service disruptions [11].…”

Risk-Aware Service Routes Planning for System Protection Communication Networks of Software-Defined Networking in Energy Internet

“…In view of the dynamics and probabilistic property of natural disasters, to improve network resilience and reduce the number of services in communication networks resulting from natural disasters, [26] proposed a risk-adaptive preventive scheme to provide an appropriate level of protection. The Authors first studied the time-varying destructive characteristics of disasters and identified the high-risk level paths in advance, then dynamically adjusted rerouting decision parameters, after that services could be switched to more reliable routing paths to achieve proactive protection.…”

Establishing effective communications in disaster affected areas and artificial intelligence based detection using social media platform

“…The devastating impact of natural catastrophes on communication backbone networks disturb both wired and wireless links (duplex communications) alike. Lack of effective communications between the inhabitants of affected areas and the rescue workers/first responders, among various rescue teams and with the rescue operation coordinating agencies result in poor management of rescue activities [5,6]. The poor flow of information also results in inaccurate analysis of situation thus, resulting in inaccurate distribution of resources.…”
