    Evaluation of livestock information network knowledge system (LINKS) based on user satisfaction
    (International Journal of Information and Communication Technology Research, 2016-08-08) Mussa, Mussa; Kipanyula, Maulilio J.; Angello, Consolata; Sanga, Camilius A.
    The advancement of technology has brought low cost mobile phones which are affordable to majority of livestock keepers and traders in Kilosa District. The Government of Tanzania has developed livestock market information system which offers markets and market information for different livestock products. The system was established to enhance the bargaining power of livestock keepers to traders and middlemen in livestock markets. Thus the ultimate goal of the developed system was to create a platform to link farmers and lenders, as well as farmers and buyers. Despite the potential of the developed system, few livestock keepers are using it. This study was designed to evaluate the usability of the livestock market information system as well as the causes of its limited use. The Software Usability Measurement Inventory approach for usability was used during system evaluation to gauge user’s satisfaction. The results indicate that development of the livestock market information system was not participatory enough. The majority of respondents indicated that the mapping of information needs was inadequate and therefore, information contents provided by the system do not meet user requirements. The results indicate the need to adopt user centred systems development involving all stakeholders in all phases of software development life cycle. Hence there is a need to improve up to date publication of market information to enable users to get reliable prices via web and mobile phones.

    Towards developing a fast reliable instant e-learning networks of distributed systems (friends) for higher education institutions in Tanzania
    (Nova Science Publishers, 2022) Mahenge, Michael P. J.; Sanga, Camilius A.
    The accessibility, availability and affordability of Information and Communication Technology (ICT) in developing countries has brought new opportunities in improving learning and teaching in Higher Education Institutions (HEIs) through E-Learning. The overwhelming development of resource-intensive contents such as video streaming, simulations, Virtual Reality (VR), augmented reality (AR), 3D graphic visualization, and others emerging educational technologies used for E-Learning applications has not only resulted into enhancing education delivery but also it has caused challenges in performance and capacity of smart mobile devices. Consequently, this chapter proposes a Mobile Edge Computing (MEC) supporting E-learning framework to reinforce learning processes in HEIs which are geographically sparsely distributed systems in different locations. Moreover, by leveraging the advanced capacity of MEC framework such as offloading, content caching closer to users, and ability to collaborate with the cloud computing, it enhances flexibility in learning, content sharing and guarantees cost-efficient learning with minimum response time. Thus in order to determine the potential of the proposed MEC-supported E-learning framework, we designed a case study and configured it in a simulation environment using edgeCloudSim simulator. The results demonstrate that the proposed framework improves average response time and content download time.
