  • 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) ...
  • Azeez, Nureni A.; Abidoye, Ademola P.; Adesina, Ademola Olusola; Agbele, Kehinde K.; Iyamu, Tiko; Venter, Isabella M. (Akamai University, 2011)
    Currently, both Peer-to-Peer Computing (P2P) and Grid Computing have remained the most vibrant and useful forms of distributed computing all over the world. Their applications are such that they cut across both academia ...
  • Bidwell, Nicola J.; Lalmas, Mounia; Marsden, Gary; Dlutu, Bongiwe; Ntlangano, Senzo; Manjingolo, Azola; Tucker, William D.; Jones, Matt; Robinson, Simon; Vartiainen, Elina; Klampanos, Iraklis (Product & Systems Internationalisation, Inc, 2011)
    Designers and developers are naïve about the ways impoverished people in rural Africa innovate new uses of mobile technology to circumvent access difficulties. Here, we report on the local appropriation of an USSD ‘Callback’ ...
  • Naidoo, Vaughn; Tucker, William D. (Telkom, 2001)
    Next Generation Networks use policy-based network management and QoS protocols to provide voice services on IP networks. Large numbers of older equipment still push IP packets. We present several solutions that include ...
  • Glaser, Meryl; Tucker, William D.; Mashao, Daniel (Telkom, 2004)
    Following on the development of several prototypes, we have built a semi-automated Deaf Telephony prototype on the SoftBridge platform. This prototype relays text and speech between Deaf users on the Internet and hearing ...
  • Adesina, Ademola Olusola; Agbele, Kehinde K.; Azeez, Nureni A.; Abidoye, Ademola P. (Blue Eyes Intelligence Engineering & Sciences Publication Pvt. Ltd., 2011)
    Mobile technology has contributed to the evolution of several media of communication such as chats, emails and short message service (SMS) text. This has significantly influenced the traditional standard way of expressing ...
  • Segers, Vaughn; Connan, James (2009)
    This paper discusses an implementation for gesture recognition using eigenvectors under controlled conditions. This application of eigenvector recognition is trained on a set of defined hand images. Training images are ...
  • Tucker, William D.; Blake, Edwin H.; Marsden, Gary; Pearson, Murray; Westerveld, Rudi (Telkom, 2007)
    This paper reports on three years of research and fieldwork with a rural wireless Internet Protocol communication project. We built a long-range WiFi network and custom communication software to support a rural telehealth ...
  • Rai, Idris; Rodrigues, Anthony; Venter, Isabella M.; Mills, Godfrey; Suleman, Hussein; Edumadze, John (2011)
    The principle objective of this research was to establish what computing curricula are required for the Sub-Saharan Africa region. Input from academics, businessmen and the analyses of curricula from several African ...
  • Daniels, Francois; Tucker, William D. (Telkom, 2008)
    This paper presents a fully decentralised peer-topeer voice communication tool intended for use across mobile ad hoc networks (MANET) by distributed groups who desired collaboration. We examined the synergy between MANETs ...
  • Tucker, William D.; Blake, Edwin H. (International Information Management Corporation, 2008)
    We describe the use of Outcome Mapping to guide the design of a rural telemedicine consultation system in South Africa. While Outcome Mapping was not primarily intended to guide design, we show that it tied in well with a ...
  • Poroye, Adeola; Tucker, William D.; Norman, Michael (Telkom, 2009)
    This paper presents work in progress to explore the utility of Near Field Communication technology to secure mobile financial services. The objective is to evaluate the potential of this approach as an upcoming technology ...
  • Wu, Wilson; Radovanovic, Aleksandar; Tucker, William D. (Telkom, 2005)
    This paper presents an innovative use of the Session Initiation Protocol (SIP) for the subscription and notification of geographic information in order to provide a privacy concerned location-based service. SIP is a signaling ...
  • Kobo, Hlabishi Isaac; Tucker, William D.; Liu, Xiao Ming (Telkom, 2011)
    Situation-aware routing seeks to improve quality of service on hybrid wireless mesh networks by making routing decisions based on the current situation of the network. BATMAN-adv is a mesh routing protocol that counts ...
  • Kobo, Hlabishi Isaac; Tucker, William D. (IIMC International Information Management Corporation, 2012)
    This paper describes a situation-aware algorithm based on the current situation of a mesh network with mobile nodes that improves quality of service. After running laboratory performance tests, we concluded that a ...
  • Blake, Edwin H.; Tucker, William D. (IIMC International Information Management Corporation, 2006)
    While the social effects of Information Technology (IT) have received much attention there is very little work on targeted methodologies to develop IT applications and content in a developing world environment. This paper ...
  • Roro, Zukile; Rey-Moreno, Carlos; Tucker, William D.; Siya, Masbulele Jay (Telkom, 2012)
    This paper describes work in progress towards developing a business case and preliminary design for an 802.11-based mesh network in the remote rural community of Mankosi in the Eastern Cape province of South Africa. Aside ...
  • Lewis, John; Tucker, William D.; Blake, Edwin H. (Telkom, 2003)
    Instant Messaging is traditionally a text only a air. However, there are instances when it would be useful to bridge to other types of media, like speech. The SoftBridge is an application framework that enables this kind ...
  • Lewis, John; Tucker, William D.; Blake, Edwin H. (Telkom, 2002)
    Users and computing equipment have varying capabilities that include the abilities to exchange text and audio, engage in high bandwidth communication, etc. As the technological options increase, e ective communication ...
  • Tucker, William D.; Glaser, Meryl; Lewis, John (Telkom, 2003)
    Following on several partial prototypes, we built an automated Deaf Telephony bridging application with the SoftBridge platform. The SoftBridge performs multi-modal bridging in real-time using Text-to-Speech (TTS) and ...
