A framework for sharing broadband infrastructure in South Africa : a case of rural community.

Mkhomazi, Sharol Sibongile. January 2013 (has links)
D. Tech. Computer Science and Data Processing (Business Information Systems) / The research examined the interplay between actors in the deployment of shared telecommunication infrastructures such as broadband. The study was conducted from a social context perspective, in three-fold. This includes understanding of sharing telecommunication infrastructures in rural areas; investigation of the influencing factors; and the roles of the community members. The analysis and interpretation of the empirical data revealed that the interaction amongst actors, which manifests from processes, politics and legislation are critical in the deployment of shared telecommunication infrastructures in South Africa rural areas. Based on the findings from the study, a Telecommunication Infrastructure Sharing framework was developed. The Telecommunication Infrastructure Sharing framework is aimed at guiding shared broadband deployment in the rural areas of South Africa.

Frame Partitioning in WiMax Mesh Mode

Albluwi, QUTAIBA 02 October 2008 (has links)
WiMax or the IEEE 802.16 standard is one of the most promising broadband wireless technologies nowadays. It is characterized by its high data rates, large coverage area, flexible design and QoS support. The standard defines two modes of operation: Point-to- Multi-Point (PMP) and the Mesh Mode. In the first mode, all nodes are connected directly to the base station and communication is not allowed amongst nodes. In the mesh mode, nodes are placed in an ad hoc manner communicating to neighbors and relaying the traffic of other nodes. The goal of this thesis is to design a partitioning scheme for the frame structure of the Mesh mode. Increasing the frame utilization would result in better support for QoS applications and optimized resource allocation, and thus revenue increase from the service provider’s perspective. The mesh frame is divided into control and data, which are further divided into centralized and distributed portions. We propose a novel and efficient scheme for partitioning the data subframe between the two schedulers. We use a Markovian model that studies the system behavior in the long run, and provides predictions based on analysis of previous window of frames. We further enhance the decision by tuning the partitioning through statistical analysis of smaller windows to accommodate demand changes. Our simulations show that the proposed scheme achieves high utilization under different network and traffic conditions and decreases the packet overflow. / Thesis (Master, Computing) -- Queen's University, 2008-10-02 18:41:36.551
