  • 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 ...
  • 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 ...
  • Chininthorn, Prangnat; Glaser, Meryl; Freudenthal, Adinda; Tucker, William D. (IIMC International Information Management Corporation, 2012)
    This paper presents a case for iterative community-based co-design to facilitate the emergence of an innovative mobile system to address a potentially life-threatening scenario for Deaf people in South Africa. For Deaf ...
  • Mutemwa, Muyowa; Tucker, William D. (Telkom, 2010)
    This paper describes how a deaf to hearing communication aid built for a mobile phone can be used to provide semi-synchronous communication between a Deaf person and a hearing person who cannot sign. Deaf people with access ...
  • Adesina, Ademola Olusola; Nyongesa, Henry O. (Telkom, 2013)
    Patients using the Mobile-Health Information System can send SMS requests to a Frequently Asked Questions (FAQ) web server with the expectation of receiving an appropriate feedback on issues that relate to their health. ...
  • Chitedze, Zimani; Tucker, William D. (Telkom, 2011)
    This paper addresses mobility management issues in an environment with both wireless LAN and wireless mesh networks. We first examine wireless mesh network client side transparency within mesh mobility management protocols ...
  • Tucker, William D.; Vuza, Xolisa; Chetty, Marshini; Blake, Edwin H.; Marsden, Gary; Pearson, Murray; Westerveld, Rudi (2007)
    For four years we have been iteratively evolving MUTI, a rural telehealth system, for hospitals and clinics in a remote rural part of the Eastern Cape in South Africa (Chetty, 2005; Chetty et al., 2003, 2004a; Maunder et ...
  • Agbele, Kehinde K.; Adesina, Ademola Olusola; Nyongesa, Henry O.; Febba, Ronald (Medwell Journals, 2010)
    The significant roles play by ranking function in the performance and success of Information Retrieval (IR) systems and search engines cannot be underestimated. Diverse ranking functions are available in IR literature. ...
  • Agbele, Kehinde K.; Adesina, Ademola Olusola; Azeez, Nureni A.; Abidoye, Ademola P.; Febba, R. (Academic Journals Inc., 2011)
    This study presented DROPT; an acronym for Document ranking Optmization algorithm approach, a new idea for the effectiveness of meaningful retrieval results from the information source. Proposed method extracted the frequency ...
  • Tucker, William D.; Blake, Edwin H.; Marsden, Gary (Telkom, 2004)
    We looked for and found two situations within the South African Digital Divide where constant and severe macro-scale latencies would most likely interfere with the usage of Information and Communication Technology (ICT) ...
