“…In practice, to speed up post-disaster recovery, it may be possible (with proper equipment) to provide temporary backup service while repair work is going on. Hence, network operators are building disaster recovery systems [5]- [10] that restore connectivity, storage, and computing facilities using specialized recovery trucks as "temporary relief". This can mitigate service disruption for end-users during repair process of failed components.…”

Next-generation optical metro-access networks are expected to support end-to-end virtual network slices for critical 5G services. However, disasters affecting physical infrastructures upon which network slices are mapped can cause significant disruption in these services. Operators can deploy recovery units or trucks to restore services based on slice requirements. In this study, we investigate the problem of slice-aware service restoration in metro-access networks with specialized recovery trucks to restore services after a disaster failure. We model the problem based on classical vehicle-routing problem to find optimal routes for recovery trucks to failure sites to provide temporary backup service until the network components are repaired. Our proposed slice-aware service-restoration approach is formulated as a mixed integer linear program with the objective to minimize penalty of service disruption across different network slices. We compare our slice-aware approach with a slice-unaware approach and show that our proposed approach can achieve significant reduction in service-disruption penalty.

“…a) Emergency networks based on transportable nodes: The relevant literature presents solutions with a wide range in set-up complexity and capabilities offered. A complete wireless mesh network based on MDRU (movable and deployable resource unit) nodes was developed and tested by Sakano et al [48]. MDRUs are network nodes (carried in a van) that offer connectivity to the Internet using satellite, pre-installed optical fibre cables or surviving wireless access gateways.…”

Abstract-Recent natural disasters have revealed that emergency networks presently cannot disseminate the necessary disaster information, making it difficult to deploy and coordinate relief operations. These disasters have reinforced the knowledge that telecommunication networks constitute a critical infrastructure of our society, and the urgency in establishing protection mechanisms against disaster-based disruptions.Hence, it is important to have emergency networks able to maintain sustainable communication in disaster areas. Moreover, the network architecture should be designed so that network connectivity is maintained among nodes outside of the impacted area, while ensuring that services for costumers not in the affected area suffer minimal impact.As a first step towards achieving disaster resilience, the RE-CODIS project was formed, and its Working Group 1 members conducted a comprehensive literature survey on "strategies for communication networks to protect against large-scale natural disasters," which is summarized in this article.Index Terms-vulnerability, end-to-end resilience, natural disasters, disaster-based disruptions.

“…The broadband wireless networks, for instance, long-term evolution (LTE), and future 5G communication system have recently gained tremendous attention due to their capacity, reliability and spectrum efficiency. Therefore, we need to investigate how they may fulfill to the mission critical requirements of public safety communication, specifically, during and after the disasters occur [1]. As a result, the post-disaster communication network requires a robust, reliable, energy efficient and spectral efficient wireless network infrastructure.…”

The wireless communication is an integral part of the society, however, wireless network infrastructure may not fully function during post-disaster wireless network scenario in which we need wireless services even more than normal circumstances. In such post-disaster scenarios, the base stations (BS) could possibly be dysfunctional or overloaded by an excessive number of user calls or data, whereas user terminals are likely to be partially connected to or fully isolated from the BS radio signals. In this paper, we study the network behavior during the post-disaster when BSs undergo the thinning process due to the damage to the network infrastructure. During network recovery phase, we also study the network performance when new temporary BSs are distributed which will bring the network into BS superposition phase. Furthermore, Device-to-Device (D2D) assisted cellular communication helps to increase the link level network connectivity which is highly appreciated during postdisaster network scenario because the network coverage is more desirable than the network throughout in such cases. We also present the analytical study of D2D and cellular communication and show that it will effectively increase the network coverage which may ultimately save many lives during the golden hours of post-disaster phase.
