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 ... -
SignSupport: a limited communication domain mobile aid for a Deaf patient at the pharmacy
(Telkom, 2013)This paper discusses a prototype for a communication aid on a mobile phone to support a Deaf1 person visiting a public hospital pharmacy. The aim is to prevent problems of non-compliance to treatment due to poor communication ... -
SIP presence location service
(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 ... -
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 ... -
Situation-aware routing for wireless mesh networks with mobile nodes
(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 ... -
Socially aware software engineering for the developing world
(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 ... -
Socio-economic aspects of voice-over-IP technology in rural SA
(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 ... -
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 ... -
A Softbridge with carrier grade reliability using JAIN SLEE
(Telkom, 2004)We have built a SoftBridge prototype within a JAIN (Java APIs for the Integrated Network) SLEE (Service Logic Execution Environment). A SoftBridge is a semi-synchronous multimodal IP (Internet Protocol) -based communication ... -
SoftBridge: a multimodal instant messaging bridging system
(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 ... -
SoftBridge: an architecture for building IP-based bridges over the digital divide
(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 ... -
Telecommunications bridging between deaf and hearing users in South Africa
(2004)This paper presents a description of telecommunications for Deaf people in South Africa by contrasting the situation in the developed world. We explain the main motivations for providing a locally appropriate solution. ... -
Telemedicine using VoIP combined with a store and forward approach
(Telkom, 2004)Rural areas in South Africa have unique conditions such as remoteness and scarcity of reliable public facilities. Information and Communication Technologies (ICTs) introduced into these areas must be suitable for these ... -
Telgo323: an H.323 Bridge for deaf telephony
(Telkom, 2002)We have developed a prototype bridge that relays text and speech between Teldem, a text telephone for the Deaf, and a standard telephone or H.323 endpoint. Telgo323 uses modified H.323 media gateways and open source Text ... -
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 ... -
Towards a sustainable business model for rural telephony
(Telkom, 2012)This paper presents the work done thus far towards designing a sustainable business model for rural telephony in the community of Mankosi, located in the Eastern Cape province of South Africa. The pillars of the model are ... -
Towards communication and information access for deaf people
(SAICSIT, 2014)In tightly circumscribed communication situations, an interactive system resident on a mobile device can assist Deaf people with their communication and information needs. The Deaf users considered here use South African ... -
Tuning a mid-range rural WiFi-based mesh network
(ACM, 2013)Little is known about how mid-range, or several km, dis- tances a ect multipoint-to-multipoint links when single ra- dio nodes with omnidirectional antennas are used. In this poster, a real network with these characteristics ... -
