- ItemContext-Aware VoIP Congestion Control Service(LINK Centre, University of the Witwatersrand (Wits), Johannesburg, 2011-02-15) Agutu, Gordon; Djouani, Karim; Biermann, Elmarie; Noel, GuillaumeIP networks can have difficulty coping with delay-sensitive VoIP traffics during emergency situations caused by fires and related disasters. During emergencies there is a huge increase in voice and video traffic, causing a huge strain on the network. The strain on the network is as a result of both essential and non-essential traffic. In such crisis situations, calls originating from or destined for rescue personnel, such as doctors and police, are considered essential. Any other calls from eyewitnesses and the public are considered non-essential, since they degrade the quality of service for the emergency response teams by consuming the scarce network resources. Providing the rescue team with the quality of service that they require necessitates network access restriction for non-essential traffic. In this paper, the authors present a voice and video service that uses Context-Awareness and Semantic Web technologies to restrict network access to privileged users during crisis situations. The service monitors the network for crisis conditions, enables the network to respond appropriately when a crisis occurs, detects the end of the crisis and reverts to its default state.
- ItemServicing Advocacy in E-Government: Small Business Development Services in Cape Town(LINK Centre, University of the Witwatersrand (Wits), Johannesburg, 2011-02-15) Mitrovic, Zoran; Bytheway, AndySmall businesses are widely regarded by national and international bodies, including the South African government, as an “engine of economic growth”. However, much available evidence suggests that establishing a new small business in South Africa is difficult because of a lack of appropriate support. The research reported here sets out to examine the actual support that has been available, and the viewpoints of both the support service providers and the intended beneficiaries – small business owners and managers. It was found that government-based support services were predominant in the minds of small businesses and other involved parties, and that much of the interest in these services was based on accessibility via the Internet, a form of electronic government service. However, despite claims of success by e-government service providers, it is found that many small businesses are not aware of available support services, and that, where they are known, there is scepticism about the benefits of engaging with them. As the problems have been found to be centred around a lack of awareness of available services, this article reports on a possible solution, based on a concept referred to here as Servicing Advocacy.
