“…Such a problem can be treated by introducing redundant power sources that the network may use in case of a disaster so as to avoid any compromises to its correct behaviour. In the design of a Never Die Network (NDN) presented in [44], selfpowered fixed wireless network stations, cognitive mobile stations and wireless balloon stations represent a set of solutions to tolerate energy outage without affecting the network. Also in [45], there is a discussion of a planning framework to reduce telecommunication network power supply vulnerability during natural (earthquakes, hurricanes, storms and blizzards for example) and man-made disasters.…”

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.

“…eNBs at local cell sites have battery backups, which may last for up to 8 hours depending on traffic loads at the site [3][4]. The number of cell phone call requests immediately after a natural disaster incident shoots up to 8 to 10 times more than during normal situations [5]. In recent times, multiple counter mechanisms are proposed that mostly aim at increasing the backup power capacity in base stations.…”

“…These include the use of fuel cells and hydrogen back up power supply as well as providing base stations with powerful generators that are able to sustain longer [6][7][8]. A robust never die network (NDN) constituting of self-powered fixed base stations, cognitive mobile base stations and wireless balloon stations is proposed in [5]. The sudden substantial spikes in network traffic load in the disaster areas overwhelm the transmission capabilities of the network resulting in a lack of spectrum availability for communication.…”

Abstract-Telecommunication networks often face power outage problems in the natural disaster affected areas. Also, owing to a sudden substantial increase in network traffic loads the battery backup power of the base stations run out quickly and therefore hampering telecommunication services. To overcome this system performance issues, we propose a Long Term Evolution (LTE)-Advanced (LTE-A)-based user equipment (UE)-controlled and base station (Evolved Node B or eNB)-assisted handover scheme. The idea is to limit the arrival of new traffic to an already overloaded eNB by diverting their handover to lightly loaded nearby eNBs. The novelty of this work is the ability of an UE to self-detect the occurrence of a natural disaster and to self-select the most suitable target eNB (TeNB) to handover with in the disaster affected areas. The handover is performed by obtaining the weighted average score (WAS) of the direction of motion (DoM) and the leftover battery backup power of the different neighboring eNBs (NeNB). The UE also predicts its DoM and dynamically adjust the weights of the two parameters if it's a disaster situation. Preliminary simulation results show that the scheme can offer up to 65% handover success rate in disaster situations.Keywords-natural disaster, seamless handover, leftover power, base station, LTE-A, weighted average score, movement prediction

“…Even if there is a wide panorama of solutions to enhance PSNs, actual assessments of disaster response capabilities in terms of response time and available capacity have underlined the limitations [7] of current PSNs and the open issues in case of real disasters (e.g., Japan Earthquake 2011). The main problems of that inefficiency are due to the following: Thus, future 5G networks can provide the right infrastructure to address all the above problems via dedicated interfaces for ultrareliable low-latency communications (URLLCs), supported by efficient virtualization, slicing, and dynamic adaptation: this can guarantee an effective amount of bandwidth and significantly lower delays under critical conditions as well.…”

Achieving the low-latency constraints of public safety applications during disaster could be life-saving. In the context of public safety scenarios, in this paper, we propose an efficient radio resource slicing algorithm that enables first responders to deliver their lifesaving activities effectively. We used the tool of stochastic geometry to model the base station distribution before and after a disaster. In addition, under this umbrella, we also proposed an example of public safety scenario, ultrareliable low-latency file sharing, via in-band device-to-device (D2D) communication. The example scenario is implemented in NS-3. The simulation results show that radio resource slicing and prioritization of first responders resources can ensure ultrareliable low-latency communication (URLLC) in emergency scenarios.
