  • Blignaut, Rénette; Venter, Isabella M.; Cranfield, D.J. (Computer Society of South Africa, 2000)
    A computer-based training (CBT) system was used to teach Computer Literacy to full-time students at the University of the Western Cape. This approach was successful in creating computer literate students as well as creating ...
  • Chitedze, Zimani; Tucker, William D. (Telkom, 2012)
    This paper shows that mobility management protocols for infrastructure Internet may be used in a wireless mesh network environment. Mesh topology tends to be an unplanned graph and routes change dynamically and in this ...
  • Benjamin, Anita; Tucker, William D. (Telkom, 2003)
    We have built a hybrid voice/text web–board that utilizes floor control for handling resources such as microphone and interface events. The aim of this research is to determine the most appropriate floor control mechanism ...
  • Paulse, Tania M.; Tucker, William D. (Telkom, 2000)
    The multi-service, multi-architecture nature of NGNs is so complex that the management of services, in addition to networks, emerges as a research challenge. Despite QoS limitations, VoIP (as opposed to VoATM), dominates ...
  • Tucker, William D.; Keats, Derek (Telkom, 1998)
    Grafting an ATM network onto an existing Ethernet network is a non-trivial exercise in network configuration. The process of mating ATM technology to an Ethernet network without tampering the underlying backbone and network ...
  • Julius, Elroy P.; Tucker, William D. (Telkom, 2005)
    This paper presents an empirical solution for guaranteeing the delivery of synchronous and asynchronous messages within a semi-synchronous IPbased communication domain. The communication infrastructure that is needed between ...
  • Julius, Elroy P.; Tucker, William D. (Telkom, 2004)
    This research aims to find an empirical solution for guaranteeing the delivery of synchronous and asynchronous messages within a semi-synchronous IP-based communication domain. The communication infrastructure that is ...
  • Adesemowo, A. Kayode; Tucker, William D. (Telkom, 2003)
    As mobile devices and networks become more data-centric, text messaging requires an extension of co-presence capabilities for better interactive discussion between input/output handicapped handheld users and their free ...
  • Agbele, Kehinde K.; Nyongesa, Henry O.; Adesina, Ademola Olusola (Medwell Journals, 2010)
    This study examines issues pertinent to the rapidly evolving use of information as a currency of modern economies. Access to information has important benefits that can be achieved in many areas including, social-economic ...
  • Motlhabi, Michael B.; Tucker, William D.; Parker, Mariam B.; Glaser, Meryl (ACM, 2013)
    The computing for development community knows how to build user interfaces using qualitative methods for text il- literate users, especially on mobile devices. However, lit- tle work has been done speci cally targeting ...
  • Henney, Andre J.; William D. Tucker (ACM, 2013)
    This work in progress paper reports on initial research into the protection of information of the individuals that make use of video relay services. Our research team has developed an application called SignSupport, to aid ...
  • Adesemowo, A. Kayode; Tucker, William D. (Telkom, 2004)
    A text only Instant Messaging (IM) built on the IETF open standard SIP/SIMPLE has been developed in line with our proposed introduction of a user-defined text Hotkey feature. These act as an on-click Affective Gesture (AG): ...
  • Adesemowo, A. Kayode; Tucker, William D. (SAICSIT in association with ACM, 2005)
    Text communication can be perceived as lacking in chat spontaneity, or plastic, due to medium limitations during interaction. A form of text messaging, Instant Messaging (IM), is now on the uptake, even on mobile handhelds. ...
  • Naidoo, Vaughn; Tucker, William D. (Telkom, 2000)
    With QoS available on IP-dominant NGNs, Policy-based Network Management (PBNM) is an effective mechanism for managing services as opposed to actual devices. IP is ubiquitous, and any NGN must contend with legacy devices ...
  • Kobo, Hlabishi Isaac; Tucker, William D.; Norman, Michael (Telkom, 2010)
    This paper discusses a way of offering voice instant messaging based on Internet Protocol using Session Initiation Protocol. The purpose of this investigation is to enhance the modern social communication amongst the people ...
  • Jeffries, Michael; Tucker, William D. (Telkom, 2001)
    The Session Initiation Protocol and H.323 dominate the Voice over IP world. These signaling protocols are responsible for call setup and call tear down by IP telephony solutions. This project analyses and discusses the ...
  • Jeffries, Michael; Tucker, William D. (Telkom, 2000)
    Current VoIP signaling protocols are interoperable with the PSTN SS7 via H.323-to-SS7 or SIP-to-SS7 gateways. As we move toward the Next Generation Network, the PSTN falls away and we work toward carrier-grade VoIP ...
  • Vuza, Xolisa; Tucker, William D. (Telkom, 2004)
    We intend adding video messaging and conferencing to Multimodal Telemedicine Intecommunicator (MuTI), a previous system that has already been in place in the target environment. This is to allow a semi-synchronous communication ...
  • Yi, Long; Connan, James (Association for Computing Machinery, 2007)
    Self-tuning has been an elusive goal for operating systems and is becoming a pressing issue for modern operating systems. Well-trained system administrators are able to tune an operating system to achieve better system ...
  • Yi, Long; Tucker, William D. (Telkom, 2008)
    This paper describes Kiara, an open source SIPbased communication system that provides the building blocks to enable Deaf relay services. We have implemented a prototype that provides real-time text, voice and video to a ...
