  • Zulu, Docas Dudu; Tucker, William David (Telkom, 2010)
    This paper describes work in progress on call capacity optimization for voice over Internet Protocol on wireless mesh networks. In a developing country such as South Africa, evidence has shown that rural inhabitants find ...
  • Mutemwa, Muyowa; Tucker, William David; Norman, Michael (Telkom, 2009)
    This paper discusses how an Instant Messaging application on a computer can use Bluetooth in order to provide vibration notification on a mobile phone. The initial motivation was to aid Deaf1 office workers to know when ...
  • Abdalla, Taha; Rey-Moreno, Carlos; Tucker, William David; Bagula, Antoine (Telkom, 2015)
    Wireless Mesh Networks (WMNs) have emerged as an alternative option to the wired networks in areas where wired deployment is unfeasible and/or costly. They have been widely adopted in community networks as these networks ...
  • Rey-Moreno, Carlos; Ufitamahoro, Marie Josee; Venter, Isabella; Tucker, William David (ACM, 2014)
    Access to information and communication technologies re- mains una ordable for many in rural areas despite recent progress in providing voice services to remote communities. The sustainability of alternative technical ...
  • Reitmaier, Thomas; Bidwell, Nicola J.; Siya, Masbulele Jay; Marsden, Gary; Tucker, William David (IIMC International Information Management Corporation, 2012)
    We describe designing an asynchronous, oral repository and sharing system that we intend to suit the needs and practices of rural residents in South Africa. We aim to enable users without access to personal computers to ...
  • Rey-Moreno, Carlos; Roro, Zukile; Tucker, William David; Siya, Masbulele Jay (ACM, 2013)
    Given the needs for a clean and easy way to maintain and secure powering wireless networks in rural areas and to gen- erate revenue to guarantee the sustainability of its intended goals, an innovative approach to leverage ...
  • Blignaut, Renette; Venter, Isabella M. (Stellenbosch University, 2011)
    Summary: The new school-leaving certificate, the National Senior Certificate (NSC), was awarded for the first time in 2008. This necessitated a relook at the entrance requirements for university, as the school subjects ...
  • Tucker, William David (ACM, 2004)
    Connecting people across the Digital Divide is as much a social effort as a technological one. We are developing a community-centered approach to learn how interaction techniques can compensate for poor communication across ...
  • Agbele, Kehinde K.; Adesina, Ademola Olusola; Azeez, Nureni A.; Abidoye, Ademola P. (Institute of Electrical and Electronics Engineers (IEEE) Inc., 2012)
    There is a growing interest in the use of context-awareness as a technique for developing pervasive computing applications that are flexible and adaptable for users. In this context, however, information retrieval (IR) is ...
  • Blake, Edwin H.; Tucker, William David; Glaser, Meryl; Freudenthal, Adinda (Wiley, 2011)
    The process of community-based co-design is one that explores various solution configurations in a multi-dimensional design space whose axes are the different dimensions of requirements and the various dimensions of designer ...
  • Blake, Edwin H.; Tucker, William David; Glaser, Meryl; Freudenthal, Adinda (Wiley, 2011)
    The process of community-based co-design is one that explores various solution configurations in a multi-dimensional design space whose axes are the different dimensions of requirements and the various dimensions of designer ...
  • Azeez, Nureni A.; Abidoye, Ademola P.; Agbele, Kehinde K.; Adesina, Ademola Olusola (Academic Journals Inc., 2012)
    Grid computing is an emergent computing innovation which offers endless access to computing infrastructure across various organizations (academia and industry). Since this technology allows aggregation of various computer ...
  • Renaud, Karen; Blignaut, Renette; Venter, Isabella M. (Springer, 2013)
    Designing for diversity is a laudable aim. How to achieve this, in the context of mobile phone usage by South African seniors, is a moot point. We considered this question from two possible perspectives: universal ...
  • Chetty, Marshini; Tucker, William David; Blake, Edwin H. (SAICSIT, in assocation with ACM, 2004)
    The digital divide between rural and urban areas within developing countries is vast. We investigate how to address this divide by introducing Information and Communication Technologies (ICTs) into remote rural areas. Our ...
  • Adesina, Ademola Olusola; Nyongesa, Henry O.; Agbele, Kehinde K. (IIMC International Information Management Corporation, 2010)
    Digital watermarking is the art of embedding data, called a watermark, into a multimedia object such that the watermark can be detected or extracted later without impairing the object. Concealment of secret messages inside ...
  • Iraba, M. Louise; Venter, Isabella M. (ACM, 2011)
    This paper discusses how to empower rural farmers to do business by means of inexpensive mobile technologies. In particular, the aim is to take advantage of the inexpensive features of low-end mobile phones to access market ...
  • Agbele, Kehinde K.; Adesina, Ademola Olusola; Ekong, Daniel; Seluwa, Dele (Institute of Electrical and Electronics Engineers (IEEE) Inc., 2011)
    The association connecting information and communication technologies (ICTs) and well-being or poverty remains vague and research today has resulted to divergent conclusions. This paper defines ICTs as “tools” that facilitate ...
  • Adesina, Ademola Olusola; Agbele, Kehinde K.; Februarie, Ronald; Abidoye, Ademola P.; Nyongesa, Henry O. (Academy of Science of South Africa, 2011)
    The sensitivity of health-care information and its accessibility via the Internet and mobile technology systems is a cause for concern in these modern times. The privacy, integrity and confidentiality of a patient’s data ...
  • Hersh, Marion A.; Tucker, William David (Elsevier, 2005)
    There are a number of pressures on researchers in academia and industry to behave unethically or compromise their ethical standards, for instance in order to obtain funding or publish frequently. In this paper a case study ...
