Enhancing user experience in 5G networks through dynamic mode selection in D-2-D mobility management scheme

The neediness of cordless apps and offerings with high bandwidth requirements over the years has increased the demand for high-speed internet and data volumes exponentially. Current wireless networks like 4G LTE technology face issues from this increase in demand as they battle to keep up with users’ growing demands. To satisfy the rising demand for wireless data, 5G cellular networks have been created as a solution to this issue. D-2-D communication has emerged as a brand-new cellular communication paradigm. This technology enables the User Equipment (UE) in 5G cellular networks to instinctively communicate without going through the evolved Node-B (eNB). D2D communications enhance the efficiency and capacity of wireless networks and play a crucial part in ensuring the level of service quality (QoS). However, several unresolved issues, such as mode selection, need to be addressed and mobility management for better performance. It should be managed wisely so that it provides lower latency, less complexity, lower power consumptions, and minimum potential data continuity connection which are primary for cell phone networks of the future. In this paper, we proposed an updated D-2-D mobility management protocol that is performance-based and enhances the user experience in 5G networks utilizing mode selection. The proposed scheme considers the user’s travel between different locations which is the mobility patterns of devices and dynamically selects the optimal mode of communication to minimize the handover delay.

Институциональные основы аудита

The article presents an overview of the development of the system of institutional regulation of auditing activities in Russia. A comparison was made of previously adopted Russian auditing standards and international auditing standards that are currently in force in the Russian Federation. At the same time, the question was raised about the advisability of introducing international auditing standards in the Russian Federation and abolishing Russian auditing standards, which were already developed taking into account international auditing standards, but in Russian and adapted to Russian accounting and auditing practice. The article presents the dynamics of the number of legal entities and individuals eligible to carry out audit activities in Russia and the dynamics of their income for the period from 2018 to 2022. Based on the eight principles of institutional design formulated by E. Ostrom at the end of the 20th century, the authors propose the basic principles necessary for determining the institutional framework for audit, the observance of which will ensure the development of audit activities and maintaining a high level of audit services quality.

Lifting a regulatory millstone around 5G investors’ neck – 5G network slicing versus EU-net neutrality?

Highly quality-sensitive 5G use cases, such as metaverse-type applications, connected and autonomous driving or digitalised health applications, are the future of the mobile internet. These use cases will rely on 5G network slicing technology to ensure scalability and individually calibrated Quality of Service (QoS) levels. New electronic communications services ensuring specific QoS levels are subject to EU-net neutrality rules laid down in Regulation (EU) 2015/2120 and are currently being assessed by national regulatory authorities (NRAs) on a case-by-case basis. As acknowledged by the European Commission (EC) in its recent report on the implementation of the provisions of Regulation (EU) 2015/2120, this case-by-case approach results in legal uncertainty and acts as barrier to investments and innovation. In particular, it is often unclear to internet service providers (ISPs) if innovative quality-sensitive content, applications or services may be delivered via specialised services in accordance with Article 3 (5) of Regulation (EU) 2015/2120. The purpose of the article is to show a way to enhance legal certainty in the application of Article 3 (5) of Regulation (EU) 2015/2120 while preserving the fundamental digital rights of end-users regarding equal and non-discriminatory treatment of data traffic by ISPs as well as transparency. Specifically, striking this delicate balance could be achieved by introducing rebuttable presumptions to shift the burden of proving that “optimisation is necessary in order to meet requirements of the content, applications or services for a specific level of quality” (Article 3 (5) subpara. 1 of Regulation (EU) 2015/2120) and that specialised services are “not […] to the detriment of the availability or general quality of internet access services for end-users” (Article 3 (5) subpara. 2 of Regulation (EU) 2015/2120) away from ISPs and towards NRAs.

The construction of hotel information management mode under the trend of low carbon tourism

Abstract The management of hotels in the context of low-carbon tourism tends to be more and more information-based, and there is an urgent need to build a management model in line with information technology. In this paper, a hotel informatization management system considering customer satisfaction is established, the system objectives are designed based on the demand analysis of travelers, and the functions of subsystems are designed based on the information management activities of the system. For the analysis module of customer satisfaction, the satisfaction index system of hotel travelers is constructed based on the ACSI model, and the satisfaction index is analyzed using the PLSR method. For the database structure of the system, the system tables were divided into several interrelated information tables. In the system test, this system’s read/write rate improved by 8.26% compared with the Green Cloud system and 7.53% compared with the Golden Swan system. Regarding the fit of satisfaction analysis, this system improved by 5.53%, 18.90%, 12.29%, and 1.33% over the quadratic graph method, the Carnot model, the CCSI model, and the ECSI model, respectively. Regarding the optimization rate of services, this system improves by 8.03% compared to the Opera system. The information-based management system helps improve the hotel’s service quality and management level and also provides a solution for operators to develop users in the hotel industry.

THE IMPACT OF SERVICE QUALITY ON THE EMOTIONAL WELL-BEING OF STUDENTS: A STUDY AMONGST COLLEGE STUDENTS IN KUALA LUMPUR, MALAYSIA

The emotional well-being and mental health of students in the higher education sector have been greatly researched over the past few years since students are increasingly subjected to various stressors in their daily lives. One element of such stressors would be the impact of service quality within the educational institution itself. However, previous studies had mainly focused on the influence of service quality regarding student satisfaction or motivation and completely overlooked their emotional well-being. The purpose of this study is to examine the effect of service quality on the emotional well-being of students in higher learning institutions by employing the HESQUAL model to discern on whether emotional well-being is affected by service quality and if so, the level of its impact. Primary data have been utilised and collected through a questionnaire created according to the model discussed, and were analysed with a sample size of 105 students. The findings of this study showed that Service Quality Factors such as Physical Environment Quality, Administrative Quality and Quality of Support Facilities has an effect on the emotional wellbeing of students, supporting the objective of this study. The data illustrates how each change in the level of service quality influences a change in emotional well-being. However, it is clear that further investigations are required in the future since there are variables that could be improved upon.

Service quality dealer identification: the optimization of K-Means clustering

Service quality and customer satisfaction directly influence company branding, reputation and customer loyalty. As a liaison between producers and consumers, dealers must preserve valuable consumer relationships to increase customer satisfaction and adherence. Lack of comprehensive measurement and standardization regarding service quality emerges as a consideration issue towards the company service excellence. Therefore, identifying the service quality performance and grouping develops into valuable contributions in decision-making to control and enhance the company's intention. This study applies the K-Means Algorithm by optimizing the number of clusters in identifying dealer service quality performance. Hence, the ultimate service quality formation will be performed. The analysis found three dealer identification categories, including Cluster One, with 125 dealers grouped as good performance; Cluster Two, with 30 dealers grouped as very good performance; and Cluster Three, with 38 dealers grouped as not good performance. In order to evaluate the efficacy of optimum k value, the lists of testing approaches are conducted and compared, whereby Calinski-Harabasz, Elbow, Silhouette Score, and Davies-Bouldin Index (DBI) contribute in k=3. As a result, the optimum clusters are determined through the highest performance of k values as three. These three clusters have successfully identified the service quality level of dealers effectively and administered the company guidelines for corrective actions and improvements in customer service quality instead of the standardized normal distribution grouping calculation.

Transformation to a patient-centred medical home led and delivered by an urban Aboriginal and Torres Strait Islander community, and association with engagement and quality-of-care: quantitative findings from a pilot study

BackgroundThe patient-centred medical home (PCMH) is a model of team-based primary care that is patient-centred, coordinated, accessible, and focused on quality and safety. In response to substantial population growth and increasing demand on existing primary care services, the Institute for Urban Indigenous Health (IUIH) developed the IUIH System of Care-2 (ISoC2), based on an international Indigenous-led PCMH. ISoC2 was piloted at an urban Aboriginal and Torres Strait Islander Community-Controlled Health Service in South-East Queensland between 2019–2020, with further adaptations made to ensure its cultural and clinical relevance to local Aboriginal and Torres Strait Islander people. Little is known on the implementation and impact of PCMH in the Australian Indigenous primary care setting. Changes in implementation process measures and outcomes relating to engagement and quality-of-care are described here.MethodsDe-identified routinely collected data extracted from electronic health records for clients regularly attending the service were examined to assess pre-post implementation changes relevant to the study. Process measures included enrolment in PCMH team-based care, and outcome measures included engagement with the health service, continuity-of-care and clinical outcomes.ResultsThe number of regular clients within the health service increased from 1,186 pre implementation to 1,606 post implementation; representing a small decrease as a proportion of the services’ catchment population (38.5 to 37.6%). In clients assigned to a care team (60% by end 2020), care was more evenly distributed between providers, with an increased proportion of services provided by the Aboriginal and Torres Strait Islander Health Worker (16–17% versus 10–11%). Post-implementation, 41% of clients had continuity-of-care with their assigned care team, while total, preventive and chronic disease services were comparable pre- and post-implementation. Screening for absolute cardiovascular disease risk improved, although there were no changes in clinical outcomes.ConclusionsThe increase in the number of regular clients assigned to a team and their even distribution of care among care team members provides empirical evidence that the service is transforming to a PCMH. Despite a complex transformation process compounded by the COVID-19 pandemic, levels of service delivery and quality remained relatively stable, with some improvements in risk factor screening.

Dynamic slicing reconfiguration for virtualized 5G networks using ML forecasting of computing capacity

As 5G deployments continue to increase worldwide, new applications can fully leverage the exceptional features of the emerging mobile networks. Ultra-Reliable Low Latency Communications (URLLC) serve as an excellent example of applications highly sensitive to jitter and packet loss. To meet these demanding requirements, 5G relies on network slicing, network virtualization, and software-defined networks. This ecosystem enables the precise allocation of resources for each network slice. However, the applications’ resource demands may vary over time. In this challenging and overwhelming environment, traditional human decision-making for slice reconfiguration is not suitable anymore, due to the multitude of parameters and the need for extremely fast response times. Machine Learning (ML) comes as a tool that can enable better use of the available resources with faster and more intelligent management. This paper introduces an ML model that can predict slices’ traffic and dynamically reconfigure computational capacity. With these forecasting capabilities, the virtualized resources can be fine-tuned to suit the slices’ requirements, guaranteeing their Quality of Service (QoS). By doing so, Mobile Network Operators can make optimized use of the equipment, tailoring their needs to each service while complying with the QoS level. The results obtained demonstrate that the proposed ML model, in combination with a specific set of hysteresis rules, can accurately predict the saturation of virtualized capacity with up to 91% accuracy and proactively adapt it to the network slice requirements.

Multiobjective Optimization for Beam Hopping and Power Allocation in Dual Satellite Cooperative Transmission Networks

Since single satellite capacity is limited for hotspot areas, we propose a dual satellite (DS) cooperative transmission network to increase the number of served cells and improve the quality of service (QoS) in this article. We study the global beam hopping and power allocation in the proposed network, where the conflict between cell priority and latency is balanced. Due to the beam power impacting both cochannel interference and capacity, the two multiobjective problems are coupled. The plural method is introduced to simplify the coupled problems, which obtains a better QoS than the fixed-weight method. As the dimensionality of the beam hopping pattern increases with the number of cells, global beam hopping design is a dimensional explosion problem. The demand-weighted power (DWP)-adaptive particle marching (APM) algorithm includes roulette, stochastic exploration, and nonlinear weights strategies. It is proposed to handle high-dimensional problems and converge fast to better optimal solutions. The simulation results show that the DWP-APM algorithm performs better with a few particles than the four baseline algorithms. Compared with baseline algorithms, the DWP-APM algorithm reduces the computation time by 57% and improves the QoS level by 13.6% at least.

SCHEISB: Design of a high efficiency IoMT security model based on sharded chains using bio-inspired optimizations

Securing Internet-of-Medical Things (IoMT) devices is a multidomain task that involves analysis of attack patterns from data & control packets. Existing security models either work on pre-emptive analysis, real-time analysis or post-processing analysis of different packet types. These operations add to the complexity of data processing, which reduces Quality of Service (QoS) levels of IoMT deployments. To overcome these issues, this paper proposes design of a sharded chain based high efficiency IoMT security model that uses bioinspired optimizations. The proposed model initially deploys a novel single chained Proof-of-Medical-Trust (PoMT) based consensus technique, which assists in identification of high-trust miners. The QoS levels are continuously monitored for each block request, and a Teacher–Learner based Optimization (TLbO) model is deployed to make sharding decisions. These decisions are reconfirmed by a Particle Swarm Optimization (PSO) model, which assists in estimation of shard length under different attack types. These attacks include Spoofing, Spying, and Flooding attacks, which affects the authenticity of data samples from IoT devices under real-time scenarios. The PSO Model also recommends splitting & merging decisions based on the context of IoMT deployments. The PoMT consensus is modified to support sharded chains, and assists in reducing mining delays without compromising miner trust levels. The modified PoMT consensus is capable of selecting overlapping miner nodes, while incorporating load balancing for optimal energy consumption during the mining process. Due to these enhancements, the proposed model is able to reduce mining delay by 8.5%, while reducing energy consumption by 3.2%, and reducing access delay by 4.9% under real-time clinical scenarios.

Ambulance location routing problem considering all sources of uncertainty: Progressive estimating algorithm

The main concern of any emergency medical services (EMS) in the world is to provide quality services to emergency calls in the shortest possible time. In this paper, the Ambulance Location Routing problem (ALRP) is proposed that is a mathematical attempt to obtain optimal cost-oriented strategic decisions (locating EMS centers and allocating ambulance fleet) in a way that guarantees service quality factors like response time, service level, and definite treatment time through optimal ambulance routing. In response to the concerns that emergency medical services deal with, in this research, a novel mixed-integer two-stage stochastic programming model is developed that can consider the uncertain nature of parameters like emergency calls, travel times, and pathways, simultaneously. Considering a heterogeneous fleet of ambulances to provide specialized out-of-hospital services and to use the treatment golden time, and considering different types of patients in terms of the need to be transferred to the hospital, are among the most vital innovations of the proposed ALRP. To tackle the computational complexity, a new decomposition-based heuristic method called the Progressive Estimating Algorithm (PEA) is developed. PEA is a modified version of the classic PHA and solves its drawbacks, like the possibility of being placed in a loop or prolonging the solution time by changing the method of calculating the first stage variables in each iteration. Therefore, by considering a large number of scenarios, PEA can reach feasible near-optimal solutions more efficiently. We have employed the actual data of a city with nearly 800.000 population, as a case study to validate the proposed ALRP model and the PEA method. The obtained results demonstrate that the proposed ALRP solution is valid, and the PEA can reach the near-optimal solution, in a very reasonable time, and with no exception, outperform the PHA. The results also show that the ALRP model reduces costs on average by 30% compared to a benchmark model. In addition, it is found that the solution obtained for the case study can reduce costs by 58% compared to the current state of the EMS in this city while guaranteeing the quality of services. Furthermore, the need to use a heterogeneous fleet of ambulances and scattered stations in the region is recommended to improve the performance of EM services. Finally, the unique way of looking at the integrated problem of location, allocation, and routing in the proposed ALRP and the idea of PEA are attractive for further studies in the field of EMS planning and other optimization problems, and several suggestions for future studies are mentioned in Conclusion Section.
