  • FHMIPv6-based handover for wireless mesh networks 

    Chitedze, Zimani; Tucker, William David (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 ...
  • Floor control arbitration for a hybrid voice/text web-board 

    Benjamin, Anita; Tucker, William David (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 ...
  • A framework and toolkit for the collection and analysis of QoS statistics for voice traffic in Next Generation Networks 

    Paulse, Tania (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 ...
