The widespread proliferation of handheld devices enables mobile carriers to be connected at anytime and anywhere. Meanwhile, the mobility patterns of mobile devices strongly depend on the users' movements, which are closely related to their social relationships and behaviors. Consequently, today's mobile networks are becoming increasingly human centric. This leads to the emergence of a new field which...
In typical Opportunistic Networking (OppNets) scenarios, mobile devices collaborate to cooperatively disseminate data toward interested nodes. However, the limited resources and knowledge available at each node, compared to possibly vast amounts of data to be delivered, makes it difficult to devise efficient dissemination schemes. Recent solutions propose to use data dissemination algorithms built...
Ashesi University College moved to a peri-urban area from the center of the city of Accra, Ghana in 2011, where we were confronted with the lack of services in the new location. This challenge presented an opportunity for the university to use the resources it has - mainly experienced human resources and knowledge - to work on some of the difficulties faced by the immediate community that welcomed...
This study aims to explore innovation model of mobile cloud services based on the perspective of five-dimensional model of mobile cloud service. The findings are suggested as follows. 1. The benefit of MCaaS can be enhanced by integrating IaaS, SaaS, and PaaS; 2. Community and MCaaS are independent systems in mobile device services; 3. Due to IaaS resource commitment, the customer stickiness on the...
For children to benefit from education programmes, they need to be healthy. The provision of healthcare services in schools thus responds to the need of children but also increases the efficacy of other investments in child development, ensures better educational outcomes, achieves greater social equity and is a highly cost effective strategy. One such a strategy is South Africa's Integrated School...
With the increasing popularity of mobile devices and data demands, it seems appropriate to provide mobile users with tools to understand information on their devices. Visualisations can be quick and powerful aids for data analysis and information acquisition. This paper discusses the visualisation and interaction techniques that exist on the mobile platform. It further discusses the design and development...
Marginalized Rural Areas (MRAs) practice farming and in most cases lack basic resources and skills to improve yields, which are often poor. This has led to famine, poverty, crime and rural to urban migration. Agricultural activities when practiced very well can alleviate such challenges in the country. We are therefore, developing a cloud computing model that seeks to improve agriculture as an activity...
Rural Africans have poor access to clean and safe water compared to other developing areas. Many Information and Communication Technology (ICT) interventions have been implemented to address the information gaps that hinder improved service delivery but have subsequently failed. The inability to provide suitable content, failure to address priority needs of communities and foster local buy-in are...
The identification of epidemiological risk areas is one of the major problems in public health. Information management strategies are needed to design prevention and control of disease in the affected areas. This paper presents a model to optimize geographical data collection of suspected or confirmed disease occurrences using the USSD mobile technology, considering its wide adoption even in developing...
In this paper we describe nibble.io, an offline information kiosk that has been designed for deployment within the rural communities of developing countries. We show how a pervasive technology such as sound can be used as a method of interaction between low-end feature phones and information kiosks built using standard PC monitors. By connecting an embedded computer to a monitor we show how we are...
Today, more than half of the world's population spend their lives in cities, and this number will jump to 70 percent by 2050. Increasing population density in urban environments demands adequate provision of services and infrastructure. This explosion in city population will present major challenges including air pollution, traffic congestion, health concerns, energy and waste management. Solution...
The Internet and mobile phones are rapidly diffusing throughout communities, and it is important to understand what people are actually doing with their access to these technologies. This study seeks to improve our understanding of the motivational factors and social and economic consequences of such use among the urban poor, which is examined through the Diffusion of Innovations Theory (DoI) and...
A marketing application can provide a solution for merchants to promote their products. In the business world, often merchants as a business entity to engage in the sale of goods and / or services have difficulty in getting and keeping customers. For that the company will present a mobile marketing app that uses LBS (Location Based Service) technology. But in its development, a company increasingly...
The growing awareness that human communications and social interactions are assuming a stratified structure, due to the availability of multiple techno-communication channels, including online social networks, mobile phone calls, short messages (SMS) and e-mails, has recently led to the study of multidimensional networks. In this context we perform the first study of the multiplex mobile social network,...
In developing countries, classroom lessons are theoretical and concepts are sometimes not entirely understood within the allocated lesson time for students. There is therefore a gap between classroom lessons and students often have to supplement what is taught in class outside the classroom. A study was conducted in Zimbabwe, which uses the same textbooks countrywide, to identify the prevalent issues...
In low and middle-income countries (LMIC), providing healthcare services to the rural population has been a challenge. The distribution of the pool of skilled healthcare resources is uneven with a large concentration in cities. People from the rural areas have to travel to the cities to avail even basic healthcare facilities. In order to provide universal healthcare access, various Governments, hospitals,...
A key input to any responsible energy development project is the current state of energy consumption in the local community as well as the associated expenses. This information can be used to guide the design of the system and to plan for the project's long-term financial viability. This paper describes residential energy use and costs in Muhuru Bay, Kenya. The results are based on a 2013 household...
In spite of several efforts in the last decade by researchers and educators, expected potential from the use of mobile device technology (MDT) to effect learning transformation is largely unfulfilled. Quantifying benefits of MDTs in learning, either through achievement of learning objectives or enhancement of the process, remains problematic. Rapid changes in development and manufacture also continue...
