Research Studies

Mobile edge computing (MEC) is an emerging technology that is recognized as a key to 5G networks. Because MEC provides an IT service environment and cloud-computing services at the edge of the mobile network, researchers hope to use MEC for secure service deployment, such as Internet of vehicles, Internet of Things (IoT), and autonomous vehicles. Because of the characteristics of MEC which do not have terminal servers, it tends to be deployed on the edge of networks. However, there are few related works that systematically introduce the deployment of MEC. Also, secure service deployment frameworks with MEC are even rare. For this reason, we have conducted a comprehensive and concrete survey of recent research studies on secure deployment. Although numerous research studies and experiments about MEC service deployment have been conducted, there are few systematic summaries that conclude basic concepts and development strategies about secure service deployment of commercial MEC. To make up for the gap, a detailed and complete survey about relative achievements is presented.

Task Offloading

Mobile edge computing (MEC) provides cloud-computing services for mobile devices to offload intensive computation tasks to the physically proximal MEC servers. In this paper, we consider a multiserver system where a single mobile device asks for computation offloading to multiple nearby servers. We formulate this offloading problem as the joint optimization of computation task assignment and CPU frequency scaling, in order to minimize a tradeoff between task execution time and mobile energy consumption. The resulting optimization problem is combinatorial in essence, and the optimal solution generally can only be obtained by exhaustive search with extremely high complexity. Leveraging the Markov approximation technique, we propose a light-weight algorithm that can provably converge to a bounded near-optimal solution. The simulation results show that the proposed algorithm is able to generate near-optimal solutions and outperform other benchmark algorithms.

With the emergence and development of the Internet of Vehicles (IoV), quick response time and ultralow delay are required. Cloud computing services are unfavorable for reducing delay and response time. Mobile edge computing (MEC) is a promising solution to address this problem. In this paper, we combined MEC and IoV to propose a specific vehicle edge resource management framework, which consists of fog nodes (FNs), data service agents (DSAs), and cars. A dynamic service area partitioning algorithm is designed to balance the load of DSA and improve the quality of service. A resource allocation framework based on the Stackelberg game model is proposed to analyze the pricing problem of FNs and the data resource strategy of DSA with a distributed iteration algorithm. The simulation results show that the proposed framework can ensure the allocation efficiency of FN resources among the cars. The framework achieves the optimal strategy of the participants and subgame perfect Nash equilibrium.

PurposeInformation technology infrastructure library (ITIL) is a commonly utilized IT service management execution technique that helps IT services to be planned, designed, selected, operated and continuously improved. ITIL procedures are utilized to measure the efficiency of IT service management procedures and their association with the accelerated system development of cloud systems. The challenges faced in IT deployment and maintenance management significantly restrict cloud computing services' reliability. Therefore, this article aims to review a comprehensive study of the role of cloud computing on the ITIL processes.Design/methodology/approachEach enterprise strives to stay competitive in the market and offers the services its consumers are looking for, all in line with cost-effectiveness and client needs. The ITIL framework provides best practice guidance for IT service management that includes a collection of ample publications supplying detailed guidelines on the management of IT functions, processes, responsibilities and roles associated with IT service management. On the other hand, the way companies employ IT services with an effect on the role of enterprise infrastructure is altered by cloud computing. Hence, the investigation makes utilization of a systematic literature review (SLR) detailing crucial success factors of cloud computing execution in ITIL. The authors have recognized 35 valuable contributions, providing a comprehensive view of study in this field, of which 22 papers were found according to some filters that have been analyzed in this article. Selected articles are presented in two groups, including cloud service and cloud service providers.FindingsOwing to the overall expense of execution and problems with combining the ITIL approach with the existing organizational IT strategic strategy, ITIL adoption has begun to wane over the last few years. An established methodology for ITIL deployment that will assure long-term success for those wanting to use private cloud procurement will be the most important inference that can be taken from this article. ITIL offers a perfect platform to execute and support cloud applications effectively. IT will prevent cloud sprawl and instability, reduce the likelihood of service interruption and optimize customer loyalty by merging humans, procedures and technologies into hybrid environments.Research limitations/implicationsThis survey is more aimed at specialists such as IT experts; so, further evaluations must also be carried out in order to understand the company's views on the risks and advantages of adopting ITIL. In addition, non-English articles are not discussed in this article.Practical implicationsThe study outcomes would help suppliers of cloud computing services assess their service quality and ensure customer satisfaction with the quality of cloud computing services. The outcomes will also supply a reference for cloud infrastructure customers to assess and choose various kinds of cloud computing services.Originality/valueAn SLR with perspectives from ITIL professionals and business studies is the benefit of this report. By offering a more thorough framework that helps companies achieve efficiency, effectiveness and creativity in ITIL execution, this article would be useful for ITIL clients, decision-makers and developers.

Due to the recent developments in mobile network technology and the supply of mobile devices, services that require high computing power and fast access speed, such as machine learning and multimedia streaming, are attracting attention. Mobile Edge Computing (MEC) has emerged. MEC allows servers to be located close to users to efficiently handle these services and provides users with ultra-low latency content delivery and powerful computing services. However, there has been a lack of research into the architecture required to efficiently use the computing power and resources of MEC. So, this paper proposes hierarchical MEC architecture in which MEC servers (MECS) are arranged in a hierarchical scheme to provide users with rapid content delivery, high computing performance, and efficient use of server resources.

Urban mobility is in the midst of a revolution, driven by the convergence of technologies such as artificial intelligence, on-demand ride services, and Internet-connected and self-driving vehicles. Technological advancements often lead to new hazards. Coupled with the increased levels of automation and connectivity in the new generation of autonomous vehicles, cybersecurity is emerging as a key threat affecting these vehicles. Traditional hazard analysis methods treat safety and security in isolation and are limited in their ability to account for interactions among organizational, sociotechnical, human, and technical components. In response to these challenges, the cybersafety method, based on System Theoretic Process Analysis (STPA and STPA-Sec), was developed to meet the growing need to holistically analyze complex sociotechnical systems. We applied cybersafety to coanalyze safety and security hazards, as well as identify mitigation requirements. The results were compared with another promising method known as Combined Harm Analysis of Safety and Security for Information Systems (CHASSIS). Both methods were applied to the Mobility-as-a-Service (MaaS) and Internet of Vehicles (IoV) use cases, focusing on over-the-air software updates feature. Overall, cybersafety identified additional hazards and more effective requirements compared to CHASSIS. In particular, cybersafety demonstrated the ability to identify hazards due to unsafe/unsecure interactions among sociotechnical components. This research also suggested using CHASSIS methods for information lifecycle analysis to complement and generate additional considerations for cybersafety. Finally, results from both methods were backtested against a past cyber hack on a vehicular system, and we found that recommendations from cybersafety were likely to mitigate the risks of the incident.

Audio Data

Interviews are an established research method across multiple disciplines. Such interviews are typically transcribed orthographically in order to facilitate analysis. Many novice qualitative researchers’ experiences of manual transcription are that it is tedious and time-consuming, although it is generally accepted within much of the literature that quality of analysis is improved through researchers performing this task themselves. This is despite the potential for the exhausting nature of bulk transcription to conversely have a negative impact upon quality. Other researchers have explored the use of automated methods to ease the task of transcription, more recently using cloud-computing services, but such services present challenges to ensuring confidentiality and privacy of data. In the field of cyber-security, these are particularly concerning; however, any researcher dealing with confidential participant speech should also be uneasy with third-party access to such data. As a result, researchers, particularly early-career researchers and students, may find themselves with no option other than manual transcription. This article presents a secure and effective alternative, building on prior work published in this journal, to present a method that significantly reduced, by more than half, interview transcription time for the researcher yet maintained security of audio data. It presents a comparison between this method and a fully manual method, drawing on data from 10 interviews conducted as part of my doctoral research. The method presented requires an investment in specific equipment which currently only supports the English language.
