Recent Submissions

  • Development consortium: HCI across borders 

    Tucker, William David (Association for Computing Machinery, 2016)
    Though every country and context is unique, and much of HCI research aims to design for situatedness, there are lessons to be learned across borders, across contexts. Questions we ask include: What are common themes ...
  • Making a community network legal within the South African regulatory framework 

    Rey-Moreno, Carlos; Tucker, William David; Cull, Domonic; Blom, R. (ACM, 2015)
    Community networks often operate at the fringe of legality with respect to spectrum, network infrastructure and providing services. We have been involved with such a network in a rural community, and together with them, ...
  • Towards a scalability model for wireless mesh networks 

    Om, Shree; Rey-Moreno, Carlos; Tucker, William David (Telkom, 2015)
    Zenzeleni mesh network is a wireless ad-hoc mesh network that provides voice services using public analogue telephones to the Mankosi community in the Eastern Cape Province. We would like to improve on the network ...
  • Beyond traditional ethics when developing assistive technology for and with deaf people in developing regions 

    Tucker, William David (Springer, 2015)
    There are limitations to traditional ethical approaches and procedures when engaged in assistive technology (AT) research for Deaf people in a developing region. Non-traditional issues arise as a consequence of employing ...
  • Clustered Multi-layer Multi-protocol Wireless Mesh Networks 

    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 ...
  • ICT4D and Local Access 

    Tucker, William David; Westerveld, Rudi (John Wiley & Sons, 2015)
    Local access in the context of regions in the global South continues to undergo transformation due to the growing ubiquity of mobile connectivity and the recent appearance of what have been termed “inverse” telecommunication ...
  • Usability of an authoring tool for generalised scenario creation for signsupport 

    Duma, Lindokuhle; Chininthorn, Prangnat; Glaser, Meryl; Tucker, William David (Telkom, 2015)
    This paper presents the usability testing results for an authoring tool that generalises scenario creation for a tool called SignSupport. SignSupport is a mobile communication tool for Deaf people that currently runs ...
  • Local ownership, exercise of ownership and moving from passive to active entitlement: a practice-led inquiry on a rural community network 

    Rey-Moreno, Carlos; Sabiescu, Amalia; Siya, Masbulele Jay; Tucker, William David (CCIRDT, 2015)
    In this paper, we aim to shed light on local ownership from a double practical and theoretical perspective, and examine its meaning as well as the factors that are bound to influence its development in community based ...
  • A participatory design for a billing system: A South African case study of a community based telephony system 

    Ufitamahoro, Marie Josee; Venter, Isabella; Rey-Moreno, Carlos; Tucker, William David (ACM, 2014)
    This paper describes the role participatory design can play in developing and implementing an information and communication technology for development project in a rural area. It shows how the process of co-designing an ...
  • Rural Wireless Mesh Network Analysis on Mobile Devices 

    Tiemeni, Ghislaine Livie Ngangom; Venter, Isabella; Tucker, William David (Telkom SA, 2014)
    The aim of this research effort is to build an efficient and accurate mobile traffic generator based on open source computer-based traffic generator software. A high performance mobile traffic generator would make the ...
  • An analysis of voice over Internet Protocol in wireless mesh networks 

    Meeran, Mohammed Tariq; Tucker, William David (IEEE, 2014)
    The paper focuses on analyzing the affects of wireless mesh networks with some mobile nodes on Voice over Internet Protocol service quality. Our interest is to examine this in simulation to learn how to better deploy voice ...
  • Co-designing a billing system for voice services in rural South Africa: Lessons learned 

    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 ...
  • Towards communication and information access for deaf people 

    Blake, Edwin H.; Tucker, William David; Glaser, Meryl (SAICSIT, 2014)
    In tightly circumscribed communication situations, an interactive system resident on a mobile device can assist Deaf people with their communication and information needs. The Deaf users considered here use South African ...
  • Optimisation of SlotTime for a single-radio Mid-Range Multi-hop Wireless Mesh Network 

    Rey-Moreno, Carlos; Tucker, William David; Simo-Reigadas, Javier (Telkom SA, 2014)
    This paper presents the business context and results of an optimisation exercise for a single-radio mid-range multi-hop wireless mesh network for the provision of VoIP services. This WiFi mesh network physically covers 30 ...
  • Abstractions for designing and evaluating communication bridges for people in developing regions 

    Tucker, William David; Blake, Edwin H. (ACM, 2010)
    This paper describes two novel abstractions that help soft- ware engineers work in developing regions to align social and technical factors when building communication systems. The abstractions extend two concepts familiar ...
  • Performance Evaluation of a Wireless Network using a VoIP Traffic Generator on a Mobile Device 

    Tiemeni, Ghislaine Livie Ngangom; Venter, Isabella; Tucker, William David (ACM, 2014)
    The problem of generating different patterns of traffic to emulate real user behaviour is receiving considerable attention with the construction of new and more complex network architectures. The theoretical modelling of ...
