Secure Fog-Cloud of Things Architectures, Opportunities and Challenges
(CRC Press ,Taylor & Francis Group, 2022-01-24) Adam A . Alli; Kassim Kalinaki; Mutwalibi Nambobi; Hamid Habiba; Ibrahim LWEMBAWO
The paradigm of the Internet of Things (IoT) has emerged due to recent advances in computer hardware, software, embedded computing technologies, and communication together with reduced costs and a drastic improvement in the performance of interacting devices. IoT has become a formal means of connecting people, things, and information systems to the Internet through cyber-physical devices. This has resulted in a new breed of systems that allow real-world solutions to be implemented across countless Internet infrastructures and services such as cities, health, and agriculture
Video conferencing as a teaching mode in higher educational institutions in Uganda: teacher perception
(Inderscience Publishers (IEL), 2022-12-22) Yasin Magombe; Adam A . Alli; Mutwalibi Nambobi; Juma KASADHA
Recently, Information Communication Technologies (ICT) have gained significant usage in enabling institutions to continuously deliver education even during the COVID-19 pandemics lockdown. Its significant application in the education sphere has resulted in new capabilities at all levels of educational institutions. In Uganda, the use of video-enabled teaching is increasingly being established in universities especially during the COVID-19 lockdowns. In this study, we examine teachers’ perception of the use of video conferencing, as a mode of teaching in higher educational institutions. The findings of this study show that teachers are of the high opinion about Video Conferencing (VC) as a mode of teaching at Higher Education Institution (HEI). In the study, several challenges that included poor ICT infrastructure, slow internet connection and those related to the cost of establishing a reasonable ICT infrastructure that can support VC were revealed. We conclude our study by providing recommendations required to improve infrastructure and to create policies to support online education as a whole and in particular VC as a teaching model that bridges in person, in class and remote learning.
A Big Data Adaptability Framework in Developing Democracies, Challenges and Opportunities
(IST-Africa 2023 Conference, 2023-05-05) Adam A . Alli; Fahadi MUGIGAYI; Juma KASADHA; WALUSANSA Y. Yahya
As oil and electricity shaped prospects of many developed economies in the previous centuries, the information age is shaped by big data analytics and artificial intelligence-related mechanisms to propel future economies. Big Data analytics provide a bountiful platform of real-time facts derived from data accumulated from the government’s information and communications technologies (ICTs). In this paper, we reflect on the opportunities big data creates in reconceptualizing governance in Africa’s developing democracies. Through wellstructured systematic literature survey, we explore the applications and adaptability of big data in developing democracies and their structures of governance. We connote that governments are likely to create significant value from structured, semistructured and unstructured big data that appear naturally because of using respective ICTs governance through a big data lens. This value is in terms of inclusive egovernance, provision of government services among others.
Review of Cloud Computing Framework for the Implementation of eLearning Systems
(Uganda Higher Education Review journal, 2024-02-05) SADIKI HABIBU ASABA; Adam A . Alli; SURAJUDEEN ADEBAYO OLAWALE; YAHAYA UMAR; ABDALLAH KASULE; RASHID RAMADHAN BWAMBALE
The rapid growth in Information and Communication Technology (ICT), combined with recent events such as the Covid-19 lockdown, has had a significant impact on traditional educational systems. Today, eLearning has become a widely accepted method for delivering educational services. As a result, the ICT infrastructure needed to be expanded to keep up with the increasing numbers of users, a wide range of learning services, and the growth of educational content. However, the volatile user load and the massive storage and transfer of rich data have led to a need for the effective utilisation of server-side system resources in providing eLearning services. Cloud computing offers a dynamic provision of virtualised resources, elasticity, scalability, pay-per-use and measured service with the ability to dynamically provision and de-provision computing resources as needed. In this paper, a review of cloud-based eLearning frameworks is conducted to identify the state of the art. Different frameworks for the implementation of cloud computing-based eLearning are identified and presented. Additionally, the review provides insights into the use of cloud computing in education, current challenges in eLearning implementation, deployment strategies, and the benefits of using cloud computing for eLearning implementation.
Teaching as a Service: An Exploration of Educational Framework for Technology driven teaching for Higher Education Institutions
(IST-Africa 2024 Conference, 2024-05-24) Adam A . Alli; Ibrahim LWEMBAWO; Fahadi MUGIGAYI; Juma KASADHA
This study examined Teaching as a Service and explored the educational framework for technology-driven teaching in Higher Education Institutions (HEI) in Uganda. This was done by looking at status of ICTs in terms of device ownership, internet utilization for instructional purposes, information technology adoption, Learning Management Systems (LMS) and Enterprise Resource Planning Systems (ERP), available resources, and capacity-building initiatives as signals for utilization of technologies for teaching. A deductive approach was used to select 30 individuals from public, private, and institutionally affiliated universities, organized into groups of ten who participated in the study. The first cohort contributed insights into the initial components of TaaS framework, which were iteratively refined until a stable framework emerged. Subsequently, an examination was conducted to ascertain the presence of these components within higher education institutions (HEIs). The investigation revealed that up to 80% of the respondents predominantly utilized ICTs individually or through institutional provisions. Access to ICT was primarily facilitated via personal laptops and smartphones, bolstered by robust infrastructure and widespread broadband connectivity within most institutions. Internet accessibility was pervasive across various campus locations, with most respondents engaging with online resources daily up to 90% of use time. The study revealed that HEI are in the initial phases of adopting technologies for teaching. Adapting TaaS framework can go a long way in helping HEIs to adopt technology effectively.
Nature inspired computational offloading in fog-cloud of things ecosystem for smart city applications
(Not published, 2024-07-05) Adam A . Alli; Alam Muhammad Mahbub; Yasin Magombe
Studies leading to optimization of resources and applications in the fog-cloud of things ecosystems have gained importance. This is because these studies form the basis upon which improved performance of Internet of Things(IoT) infrastructure can be realized. In this study, we explore heuristic approach that permits offloading to optimal offsite fog by developing modified dynamic PSO(mDyPSO) mechanism. We compared our results with the traditional simple PSO(SiPSO). Our simulation results show that mDyPSO out performs SiPSO in terms of application latency, network usage and energy utilization. We note that our mDyPSO offloading mechanism improves network performance up to one third. We conclude that mDyPSO mechanism performs well in fluctuating topology. This further proves that considering multiple computational parameters to modify PSO yield better offloading Results.
