This paper investigates the interaction between network coding and link-layer transmission rate diversity in multi-hop wireless networks. By appropriately mixing data packets at intermediate nodes, network coding allows a single multicast flow to achieve higher throughput to a set of receivers. Broadcast applications can also exploit link-layer rate diversity, whereby individual nodes can trans...

We propose two design methodologies for synthesis of area-eecient Data Format Converters (DFCs) with high throughput rate. DFCs are grouped into various classes according to the speciication of design parameters. The rst design methodology is suitable for design of many representative classes of DFCs. The designs using this methodology are based on a two-dimensional architecture. They have maxi...

During the past few years science faculties at tertiary education institutions in South Africa have had to face increasing pressure from national as well as provincial government bodies to improve the student throughput rate. Various suggestions have been made to achieve this goal. This paper investigates the viability of two of these suggestions for solving the throughput problem. It is part o...

Space Time Adaptive Processing (STAP) techniques that are being developed for the next generation radar systems require very high computing power. In order to meet the real-time requirements in STAP applications, High Performance Computing (HPC) systems are used. In this paper, we present a methodology to design high throughput-rate parallel algorithms for STAP on HPC platforms. Data remapping ...

The cost of harvesting is one of the constraints in improving biofuel economics. Adjusting the ground speed of harvesting machines to maximize their throughput rate in relation to yield level is one of the ways to reduce harvesting cost. To control the ground speed of a baler, a real-time sensor that can predict the swathed-biomass yield in front of the baler would be an invaluable tool. It was...

The relative delay tolerance of data applications, together with the bursty traffic characteristics, opens up the possibility for scheduling transmissions so as to optimize throughput. A particularly attractive approach, in fading environments, is to exploit the variations in the channel conditions, and transmit to the user with the currently ‘best’ channel. We show that the ‘best’ user may be ...

The emergence of several IEEE 802.11 Physical Layer (PHY) standards such as IEEE 802.11 a, b & g operating in the range of 2.4 GHz unlicensed Industrial Scientific Medical (ISM) and 5.8 GHz UNII frequency band may lead to delays and multi-rate shifting over a large distance in a multi-hop wireless network environment; result in significance throughput degradation when devices coexist in the wir...
