    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.

    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.
