Situation-aware routing based on link quality for static mesh networks with mobile nodes
(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 ...
Asynchronous video telephony for the Deaf

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 ...
Using voice over IP to bridge the digital divide: a critical action research approach
(Telkom, 2003)
There is a great disparity between those who have access to Information and Communication Technologies (ICTs) and those that do not. This phenomenon forms part of the Digital Divide. Many ICTs may be used to help overcome ...
SoftBridge in action: the first Deaf telephony pilot
(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 ...
The role of Outcome Mapping in developing a rural telemedicine system

Developing locally relevant applications for rural areas: a South African example
(SAICSIT, in assocation with ACM, 2004)
The digital divide between rural and urban areas within developing countries is vast. We investigate how to address this divide by introducing Information and Communication Technologies (ICTs) into remote rural areas. Our ...
Floor control arbitration for a hybrid voice/text web-board
(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 ...
