“…VNE is highly related to current technology trends that will leverage automated and intelligent network management, and it will ease the development of virtualization schemes using reference frameworks [37] for 5G, beyond-5G and advanced IoT environments. On the one hand, it has been integrated with Software-defined networking (SDN) architectures due to the centralized view of the state of the substrate network and running virtual services, such as industrial wireless sensor and IoT networks [38,39]. On the other hand, it has been investigated for cellular network providers to accomplish QoS conditions, as low latency requirements [40], to deploy efficiently MEC instances efficiently [41], or to create virtual network operators for mobile users [42].…”

“…Works [Qin et al 2014, Han et al 2018, Chen et al 2019] cite the following GA strengths: (i) suitable for use when the solution space is vast; (ii) the search process is not restricted to local search spaces; (iii) it is flexible enough to be adapted to various scenarios. The evaluation function (fitness) and the chromosome structure concentrate the most sophisticated part of adapting the GA heuristic to solve a problem.…”

The 5G mobile network is based on a virtualized infrastructure and offers a virtual network (VN) creation service considering many new scenarios arising from the 5G vision. The diversity of scenarios and the instantiation of VN on-demand induce pressure on the virtual network embedding (VNE). VNE is the mapping of virtual nodes and links to real nodes and links obeying the QoS parameters present in the VN request and available resources. Since this is an optimization and NP-Hard problem, multiple efforts have been made to create VNE algorithms. Considering such efforts, this work presents: (i) a fitness function regarding multiobjective optimization; and (ii) a Parallel Differential Evolution (PDE) approach to face the VNE. We designed the PDE due to the lack of viable parallel solutions in the 5G scenario. We compared our approaches with different versions of Greedy, Stress, and Genetic Algorithms, totaling ten approaches. The results demonstrate that DE and its parallel version obtained a higher number of mapped requisitions. Also, the parallel performance decreases the execution time in certain conditions; in a favorable scenario, the parallel version obtains up 21.04% of runtime reduction.

“…This device is one of the most ideal instruments for point-topoint connections over distances up to 15 kilometers. DynaDish 5's body and cover are made from durable plastic; therefore this radio is able to make lasting connections in harsh weather conditions and is a good choice for high frequency contamination due to the antenna cover (Chen et al, 2019). Wireless radios are able to communicate within a certain range, which is considered to be circular.…”

Abstract. The effects of earthquakes on societies are greater than what most people think. These effects range from structural damages to economic impacts and fatalities. An earthquake only lasts for a few seconds and the aftershocks may continue for days, but the damage does continue for years. The lack of integrated and automated tools for estimating resources needed in the aftermath of an earthquake during the disaster response phase motivate the design and implementation of a comprehensive, interactive, and user-friendly model. The objective of this research is to use geospatial analyses for examining vulnerable areas and evaluating the hazard of building damage by earthquake. Hence, the effective parameters of damage are identified and by using the fuzzy inference, the degree of damage in the study area is determined. Subsequently, with the provision of internet service in a troubled region, it is possible to collect voluntary information from people in the region using their mobile smartphones. For this purpose, an app in the Android Studio environment has been developed for convenience and sending the exact location of the affected sites. Moreover, the result of this research identified areas with a high priority for relief and optimal use of time, especially in the early hours of the crisis.
