Design and Analysis of a Bandwidth Aware Adaptive Multipath N-Channel Routing Protocol for 5G Internet of Things (IoT)
Publication Name: Emerging Science Journal
Publication Date: 2024-02-01
Volume: 8
Issue: 1
Page Range: 251-269
Description:
Large numbers of mobile wireless nodes that can move randomly and join or leave the network at any moment make up mobile ad-hoc networks. A significant number of messages are delivered during information exchange in populated regions because of the Internet of Things' (IoT) exponential increase in connected devices. Congestion can increase transmission latency and packet loss by causing congestion. More network size, increased network traffic, and high mobility that necessitate dynamic topology make this problem worse. An adaptive Multipath Multichannel Energy Efficient (AMMEE) routing strategy is proposed in this study, in which route selection strategies depend on forecasted energy consumption per packet, available bandwidth, queue length, and channel utilization. While multichannel uses a channel-ideal assignment process to lessen network collisions, multipath offers various paths and balances network strain. The link bandwidth is split up into a few sub-channels in the multichannel mechanism. To reduce network collisions, several source nodes simultaneously access the channel bandwidth. The cooperative multipath multichannel technique offers several paths from a single source or from several sources to the destination without colliding or becoming congested. The AMMEE routing approach is the basis for path selection. A load-and bandwidth-aware routing mechanism in the proposed AMMEE chooses the path based on node energy and forecasts their lifetime, which improves network dependability. The outcome demonstrates a comparative analysis of various multichannel medium access control (MMAC) techniques, including Parallel Rendezvous Multi Channel Medium Access Protocol (PRMMAC), Quality of Service Ad hoc On Demand Multipath Distance Vector (QoS-AOMDV), Q-learning-based Multipath Routing (QMR), and Topological Change Adaptive Ad hoc On-demand Multipath Distance Vector (TA-AOMDV) and the proposed AMMEE method. The results show that the AMMEE approach outperforms alternative systems.

Description:
The educational system of the twenty-first century is student-centered. Students are the generation that has seen firsthand the enormous expansion of online media represented by the Internet, virtual reality, and artificial intelligence, which has increased the relevance of digital competence in higher education. This is because they are the ones who have grown up with the rapid development of computer networks and who have firsthand knowledge of those technologies. Additionally, the epidemic has raised public awareness of the need of for digital literacy. The increasing digitalization and modernization of every area of our lives to satisfy the needs of modern education is creating new chances for both teaching and learning. The world over, more and more technology is being used to improve training and education, which eliminates the need to take into account regional factors that are associated with traditional education. More and more educational establishments are using technology to improve instruction. The paper’s primary objective is to pinpoint the internet-related and digitalization-related variables that have an impact on higher education in European nations using the following indicators: patent applications, resident population, high-tech exports, research and development spending, and school enrollment at the tertiary level (% gross). Due to data availability, the sample includes 40 nations over the period 1996-2020. The World Bank database is the source of the information. Panel-data VAR and panel Granger causality were the methodologies we used. Our findings suggested that the Internet and digitalization considerably impact higher education because high-technology exports represent both the internet and digitalization.

Publication Name: Future Internet
Publication Date: 2023-10-01
Volume: 15
Issue: 10
Page Range: Unknown
Description:
Information and communications technologies play a vital role in achieving the Sustainable Development Goals (SDGs) and bridging the gap between developed and developing countries. However, various socioeconomic factors adversely impact the deployment of digital infrastructure, such as 5G networks, in the countries of Oceania. The high-speed broadband fifth-generation cellular network (5G) will improve the quality of service for growing mobile users and the massive Internet of Things (IoT). It will also provide ultra-low-latency services required by smart city applications. This study investigates the planning process for a 5G radio access network incorporating sub-6 GHz macro-remote radio units (MRRUs) and mmWave micro-remote radio units (mRRUs). We carefully define an optimization problem for 5G network planning, considering the characteristics of urban macro-cells (UMa) and urban micro-cells (UMi) with appropriate channel models and link budgets. We determine the minimum number of MRRUs and mRRUs that can be installed in each area while meeting coverage and user traffic requirements. This will ensure adequate broadband low-latency network coverage with micro-cells instead of macro-cells. This study evaluates the technical feasibility analysis of combining terrestrial and airborne networks to provide 5G coverage in Oceania, with a special emphasis on Fiji.

Description:
Understanding and predicting the relationship between big data analytics (BDA) and knowledge management (KM) and how they complement each other is still an ambiguous and strategically crucial issue. This study aims to investigate the interrelationships between BDA and KM in fostering green innovation practices (GIP) and organizational performance and, in addition, to explore the mediation effect of KM and how it can boost the impact of BDA on GIP. Based upon the underpinning theories that cover the study’s research model, several hypotheses were proposed and then examined. Using a cross-sectional research design, 174 questionnaires were collected from medium and large Algerian manufacturing firms. The study applied smart PLS-SEM for data analysis. The sorted results show that BDA positively impacts KM and GIP. The results also indicate that GIP positively influences and increases firm performance. In addition, the findings reveal that government support plays a significant part in leveling up firms’ GIP. Furthermore, the study emphasizes the critical impact of KM to polish the impact of BDA on GIP. This study highlights the necessity of improving the technological and managerial aspects of BDA by determining valuable capabilities, such as KM processes, to enhance organizational performance. Tracking business opportunities and predicting their relevant threats has become a severe concern to knowledge-extensive firms. Therefore, BDA can enable managers to absorb a large amount of data to increase the efficiency of a business decision to ensure survival and advancement. The study discusses both practical and theoretical implications.

Organizational Change and Workplace Incivility: Mediated by Stress, Moderated by Emotional Exhaustion
Publication Name: International Journal of Environmental Research and Public Health
Publication Date: 2023-02-01
Volume: 20
Issue: 3
Page Range: Unknown
Description:
Modern organizations continuously undergo change processes. The focus of the organizations remains on the macro level, but the micro level (i.e., employee’s perspective) is neglected. Using the conservation of resource theory (COR), this study examines the association between organizational change and workplace incivility. This study also proposes mediating and moderating mechanisms of stress and emotional exhaustion. The data were collected from 262 respondents working in public sector organizations in Pakistan using a time-lagged technique. The results proved that change significantly impacts workplace incivility. Moreover, stress mediates their relationship and emotional exhaustion moderates it. Furthermore, emotional exhaustion also moderates the stress–incivility relationship. Public sector organizations must focus on well-planned, inclusive, and adequately managed change processes to achieve the desired outcome; otherwise, adverse behaviors, including incivility, manifest. To the best of the authors’ knowledge, the organizational change and incivility relationship has not been explored in the past. Additionally, their relationship with stress and emotional exhaustion also requires empirical investigation. This study also adds to the literature on the conservation of resource theory.
