Call capacity for voice over Internet Protocol on wireless mesh networks
(Telkom, 2010)
This paper describes work in progress on call capacity optimization for voice over Internet Protocol on wireless mesh networks. In a developing country such as South Africa, evidence has shown that rural inhabitants find ...
Abstractions for designing and evaluating communication bridges for people in developing regions
(ACM, 2010)
This paper describes two novel abstractions that help soft- ware engineers work in developing regions to align social and technical factors when building communication systems. The abstractions extend two concepts familiar ...
Security of a Mesh Potato Network in Ad Hoc Mode
(Telkom, 2013)
Wireless Mesh Networks can provide low cost and reliable community-owned connectivity in developing rural areas. A rural community can use mesh networks to access a wide range of modern information and communication ...
Beyond traditional ethics when developing assistive technology for and with deaf people in developing regions
(Springer, 2015)
There are limitations to traditional ethical approaches and procedures when engaged in assistive technology (AT) research for Deaf people in a developing region. Non-traditional issues arise as a consequence of employing ...

(IIMC International Information Management Corporation, 2012)
We describe designing an asynchronous, oral repository and sharing system that we intend to suit the needs and practices of rural residents in South Africa. We aim to enable users without access to personal computers to ...
Towards a scalability model for wireless mesh networks
(Telkom, 2015)
Zenzeleni mesh network is a wireless ad-hoc mesh network that provides voice services using public analogue telephones to the Mankosi community in the Eastern Cape
Province. We would like to improve on the network ...
Walking and the social life of solar charging in rural Africa
(Association for Computing Machinery, 2013)
We consider practices that sustain social and physical environments beyond those dominating sustainable HCI discourse. We describe links between walking, sociality, and using resources in a case study of community-based, ...
FHMIPv6-based handover for wireless mesh networks
(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 ...
Mobile Communication Tools for a South African Deaf patient in a pharmacy context
(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 ...
Community-based solar power revenue alternative to improve sustainability of a rural wireless mesh network
(ACM, 2013)
Given the needs for a clean and easy way to maintain and secure powering wireless networks in rural areas and to gen- erate revenue to guarantee the sustainability of its intended goals, an innovative approach to leverage ...
