Building a semantic web-based e-health component for a multipurpose communication centre

Rural communities have limited access to health information which is made available on the internet. This is due to poor infrastructure (i.e., lack of clinics or Internet access) and that gives them problems in accessing information within the domain of health. The availability of Information and Communication Technologies (ICTs) in a rural community can provide the community with a number of beneficial solutions to their problems as they maximize the potential of knowledge sharing and delivery. This research seeks to make use of ICTs deployed in the community of Dwesa, in order to contribute to improving the health standards of the community. It seeks to accomplish this by carrying out an investigation and literature review with the aim of understanding health knowledge sharing dynamics in the context of marginalized communities. The knowledge acquired will then be used in the development and implementation of a semantic web-based e-Health portal as part of the Siyakhula Living Lab (SLL) project. This portal will share and deliver western medical knowledge, traditional knowledge and indigenous knowledge. This research seeks to make use of a combination of Free and/or Open Sources Software in developing the portal to make it affordable to the community

Real-Time Multicast Tree Visualization and Monitoring

The exponential growth of the Internet combined with the increasing popularity of streaming audio and video are pushing Internet bandwidth constraints to their limits. Methods of managing and more efficiently utilizing existing bandwidth are becoming increasingly vital. Using IP multicast to deliver content, especially streaming audio and video, can provide enormous bandwidth savings. A decade of effort at deploying multicast, combined with the rising need for better traffic management for bandwidth-hungry applications has led to significant momentum for multicast use and deployment. One of the remaining barriers to widespread adoption is the lack of multicast monitoring and debugging tools. To address this need we introduce MHealth, a graphical, near real-time multicast monitoring tool. MHealth utilizes existing tools to collect comprehensive data about Realtime Transport Protocol (RTP) based streaming audio/video sessions. By using a combination of application-level protoco..

MHealth: A real-time multicast tree visualization and monitoring tool

A decade of efforts at deploying multicast combined with the rising need for better traffic management for bandwidth-hungry audio and video applications has led to significant momentum for multicast implementation. One of the remaining barriers to widespread adoption of multicast in the Internet is the lack of multicast monitoring and debugging tools. To address this need we introduce MHealth, a graphical, near real-time multicast monitoring tool. MHealth utilizes existing tools to collect comprehensive data about Real-Time Protocol (RTP) based streaming audio/video sessions. By using a combination of application-level protocol data for participant information and a multicast route tracing tool for topology information, MHealth is able to present a multicast tree's topology and information about the quality of received data. 1
