Cost-effective mobile based learning content delivery in resources and network constrained environments
(IEEE, 2014-07-14) Mahenge, Michael; Mwangoka, Joseph; Simba, Fatuma
The advancement in Information and Communication Technologies (ICTs) has brought opportunities for new ways of learning in Higher Learning Institutions (HLIs) through e-learning systems. While these opportunities exist, e-learning contents delivery and accessibility in third world countries like Tanzania is still a challenge due to resource and network constrained environments. The challenges include: high cost of bandwidth connection and usage; high dependency on the Internet; limited mobility and portability features; inaccessibility during offline period and shortage of ICT facilities. So there is a need for a technology to bridge these gaps. This paper explores the opportunities brought by mobile technologies to find out a cost-effective solution for e-learning content delivery and accessibility in HLIs of Tanzania. Specifically, the paper proposes a Cost-effective Mobile Based Learning Content Delivery approach for resource and network constrained environments. The proposed solution has the potential to reduce the cost of bandwidth usage, and cut down server's workload and Internet usage overhead by synchronizing contents from a remote server to a local database in the user's device for offline use. It will also improve the quality of experience and participation of learners as well as facilitate mobility and portability in learning activities.
Mobile-based system for cost-effective e-learning contents delivery in resource and bandwidth constrained learning environments
(Hong Kong Bao Long Accounting And Secretarial Limited, 2014-12-01) Mahenge, Michael; Mwangoka, Joseph
The advancement in Information and Communication Technologies (ICTs) has brought opportunities for the development of Smart Cities. The Smart City uses ICT to enhance performance and wellbeing, to reduce costs and resource consumption, and to engage more effectively and actively with its citizens. In particular, the education sector is adopting new ways of learning in Higher Education Institutions (HEIs) through e-learning systems. While these opportunities exist, e-learning content delivery and accessibility in third world countries like Tanzania is still a challenge due to resource and network constrained environments. The challenges include: high cost of bandwidth connection and usage; high dependency on the Internet; limited mobility and portability features; inaccessibility during the offline period and shortage of ICT facilities. In this paper, we investigate the use of mobile technology to sustainably support education and skills development particularly in developing countries. Specifically, we propose a Cost-effective Mobile Based Learning Content Delivery system for resource and network constrained environments. This system can be applied to cost-effectively broaden and support education in many cities around the world, which are approaching the 'Smart City' concept in their own way, even with less available technology infrastructure. Therefore, the proposed solution has the potential to reduce the cost of the bandwidth usage, and cut down the server workload and the Internet usage overhead by synchronizing learning contents from some remote server to a local database in the userâ€™s device for offline use. It will also improve the quality of experience and participation of learners as well as facilitate mobility and portability in learning activities, which also supports the all-compassing learning experience in a Smart City.
Multi-agent based IoT smart waste monitoring and collection architecture
(International Journal of Computer Science, Engineering and Information Technology (IJCSEIT), 2017-10) Likotiko, Eunice David; Nyambo, Devotha; Mwangoka, Joseph
Solid waste management is one of the existing challenges in urban areas and it is becoming a critical issue due to rapid increase in population. Appropriate solid waste management systems are important for improving the environment and the well-being of residents. In this paper, an Internet of Things(IoT) architecture for real time waste monitoring and collection has been proposed; able to improve and optimize solid waste collection in a city. Netlogo Multi-agent platform has been used to simulate real time monitoring and smart decisions on waste management. Waste filling level in bins and truck collection process are abstracted to a multi-agent model and citizen are involved by paying the price for waste collection services. Furthermore, waste level data are updated and recorded continuously and are provided to decision algorithms to determine the vehicle optimal route for waste collection to the distributed bins in the city. Several simulation cases executed and results validated. The presented solution gives substantial benefits to all waste stakeholders by enabling the waste collection process to be more efficient
Using Game-Based approach to enhance language learning for preschoolers in Tanzania
(IEEE, 2014-07-14) Ongoro, Catherine; Mwangoka, Joseph
This paper presents a Game-Based approach to E-Learning that tries to mimic games to harness motivational properties in Tanzanian Preschools. A prototype system was developed, using a rapid development approach. The system was evaluated by twelve preschools across three regions in Tanzania namely Arusha, Iringa and Dar es Salaam to give an indication of the system's ability to make work with exercise in alphabetical sound articulation more engaging and fun. The pedagogical model of the application was based on learning theories. The results of the study have shown that the learning outcomes of the integrated digital-learning activities of alphabetical sound articulation among preschoolers improved. It projected that innovative digital content framework can serve as a means to inform policy makers, educators, and teachers about the potential use of Game-Based method in preschoolers' education and offer ideas and means to standardize sound articulation and language learning thus, improve the overall quality of education.
