“…The implementation of CR in the PS domain was examined and discussed in various articles. In [136], the authors suggest the cognitive emergency radio approach based on the Multiple-Access Frequency Single Carrier Division (SC-FDMA) to allow the disaster network terminal to automatically scan for spectrum resources whenever feasible in the crisis region, e.g. not used.…”

The performance of wireless communication network is important in emergency rescue operations while ensuring optimum usage of limited wireless resources. Due to the disruption of normal wireless communication in a post-disaster scenario, the sustenance of an emergency communication network plays a significant role in relief operations. Under such a scenario, it becomes crucial to monitor the performance and reliability of the protocol in a time-bound manner. Some of the prominent challenges faced by the communication network during this period are related to energy efficiency, resources allocation, reliable connectivity, QoS, network throughput, and interoperability. A comprehensive performance appraisal of the emergency network considering the above-mentioned aspects is extremely important. This review provides a comprehensive survey of the widely used communication technologies applied for setting up an emergency communication network to mitigate the post disaster aftermath. The article also delivers an overview of the integration of new technologies with the existing standards for improving the performance of the disaster communication networks. Finally, we propose some promising solutions to overcome the limitations of existing emergency communication technologies to improve the overall network performance.

“…In such catastrophic situations, an efficient deployment of mobile wireless communication nodes is an extremely challenging real problem to be tackled, since predeployed network infrastructures may be totally or partly destroyed. A dramatic evidence of this was provided by the Japan earthquake in 2011: over 14,000 cellular base stations were damaged, and one million fixed network lines were out of service [19,20]. The growing use of mobile devices during the last decade has enabled a better and quicker crisis response against disaster events [21].…”

“…Unfortunately, most of these mobile nodes in the composed networks rely on capabilities of wireless equipment, e.g., self-configuration and self-organization; they do not assume the presence of other communication infrastructures within the disaster scenario. In this context, it requires interoperability among highly heterogeneous portable equipment in terms of coverage, cost, autonomy, and other similar factors, to form a temporary DAWN, which requires reliability, interoperability, and adaptiveness [20,22]. Required mobile nodes can range from traditional RF front-ends installed on ground vehicles and portable masts to last-generation devices operating from unmanned aerial fleets of drones, helicopters, and airplanes.…”

Disaster Area Wireless Networks (DAWNs) are widely deployed in natural or man-made disaster scenes, since the communication infrastructure may be completely destroyed by the disaster. This paper proposes a hybrid network architecture for DAWNs due to the mobility of first responders and refugees. Based on the link characterization of DAWNs, we choose four essential criteria and propose a multi-criteria decision-making method for emergency communication protocol (MCDM-ECP), which utilizes the analytic hierarchy process (AHP) method and Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) method to find the optimal next-hop node in DAWNs. Routing discovery and routing maintenance processes are included in the novel protocol. The simulation results show that MCDM-ECP performs better than other classical protocols both in energy consumption and packet received rate (PRR) for long-term emergency communications.

“…These approaches are valuable for day-to-day routine activities and major planned events, because they can offer great improvements to network capacity and in consequence to the range of services and applications that PPDR users can employ. Moreover, LTE is able to exploit spectrum holes through cognitive radio access techniques [4], providing increased transmission quality and coverage. However, in most major incidents and disasters, terrestrial mobile networks are overloaded or their infrastructures are damaged and thus out of service [5].…”
