Emerging digital technologies continues to evolve posing unprecedented opportunities in health systems globally improve healthcare services delivery. There has been significant progress healthcare. However, the lack of emotive recognition coupled with a dearth personalized and pervasive applications smart devices calls for integration intelligent sensors through emerging technologies. Although there connected care, more research innovation, dissemination are needed unbundle new move towards 5.0. Healthcare is at dawn paradigm change reach era disease control detection, virtual management, monitoring, decision-making. Therefore, this study discusses roles capacities sensors, their capabilities other such as nanotechnology, 5 G technologies, drone technology, blockchain, robotics, big data, internet things, artificial intelligence, cloud computing. 5.0 provides including patient remote tracking clinics, telemedicine, ambient assisted living, self-management, wellness monitoring control, treatment reminders, compliance adherence, care. building resilience robust not immune challenges. Organizational challenges, technological infrastructural barriers, legal regulatory frameworks e-health policies, individual perceptions, misalignment hospitals' strategy, funding, religious cultural barriers identified potential successful implementation need resilient technology-driven systems. To achieve this, expanding infrastructure, provision budgetary support based on sustainable business models, develop appropriate standardization synchronization protocols, improving stakeholders' engagement involvement establishment private public partnerships investments.

Integration of digital technologies and public health (or healthcare) helps us to fight the Coronavirus Disease 2019 (COVID-19) pandemic, which is biggest crisis humanity has faced since 1918 Influenza Pandemic. In order better understand healthcare, this work conducted a systematic comprehensive review with purpose helping combat COVID-19 pandemic. This paper covers background information research overview summarizes its applications challenges in finally puts forward prospects healthcare. First, main concepts, key development processes, common application scenarios integrating healthcare were offered part information. Second, bibliometric techniques used analyze output, geographic distribution, discipline collaboration network, hot topics before after We found that pandemic greatly accelerated on integration Third, cases China, EU U.S using collected analyzed. Among these technologies, big data, artificial intelligence, cloud computing, 5G are most effective weapons Applications show play an irreplaceable role controlling spread COVID-19. By comparing three regions, we contend China's success avoiding second wave integrate large scale without hesitation. Fourth, field summarized. These mainly come from four aspects: data delays, fragmentation, privacy security, security vulnerabilities. Finally, study provides future addition, also provide policy recommendations for other countries use technology

Contributions of Smart City Solutions and Technologies to Resilience against the COVID-19 Pandemic: A Literature Review

Sustainability, Год журнала: 2021, Номер 13(14), С. 8018 - 8018

Опубликована: Июль 18, 2021

Since its emergence in late 2019, the COVID-19 pandemic has swept through many cities around world, claiming millions of lives and causing major socio-economic impacts. The occurred at an important historical juncture when smart solutions technologies have become ubiquitous cities. Against this background, review, we examine how city contributed to resilience by enhancing planning, absorption, recovery, adaptation abilities. For purpose, reviewed 147 studies that discussed issues related use during pandemic. results were synthesized under four themes, namely, planning preparation, adaptation. This review shows investment initiatives can enhance preparation ability. In addition, adoption can, among other things, capacity predict patterns, facilitate integrated timely response, minimize or postpone transmission virus, provide support overstretched sectors, supply chain disruption, ensure continuity basic services, offer for optimizing operations. These are promising demonstrate utility resilience. However, it should be noted realizing potential hinges on careful attention challenges privacy security, access open-source data, technological affordance, legal barriers, feasibility, citizen engagement. Despite this, further development unprecedented opportunities similar future events.

Survey on computation offloading in UAV-Enabled mobile edge computing

Journal of Network and Computer Applications, Год журнала: 2022, Номер 201, С. 103341 - 103341

Опубликована: Фев. 1, 2022

With the increasing growth of internet-of-things (IoT) devices, effective computation performance has become a critical issue. Many services provided by IoT devices (e.g., augmented reality, location-tracking, traffic systems, and autonomous driving) require intensive real-time data processing, which demands powerful computational resources. Mobile edge computing (MEC) been introduced to effectively handle this problem reliably over internet. The inclusion MEC server allows computationally tasks be offloaded from devices. However, communication overhead delays are major drawbacks. advantages high mobility low cost, unmanned aerial vehicles (UAVs) can mitigate issue acting as servers. offloading decisions for such scenarios involve service latency, energy/power consumption, execution delays. For reason, study reviews UAV-enabled solutions in was focus research. We compare algorithms qualitatively assess features performance. Finally, we discuss open issues research challenges terms design implementation.
