Topological arrangement of nodes in wireless networks suitable for the implementation of network coding
(North-West University, 2010)
Network coding refers to the implementation of coding methods to utilize network connections more efficiently. Network coding is commonly researched in the information theory field, but very little research is being done ...
A network traffic model for wireless mesh networks
(North-West University, 2013)
Design and management decisions require an accurate prediction of the performance of the network. Network performance estimation techniques require accurate network traffic models. In this thesis we are concerned with the ...
Comparing network coding implementations on different OSI layers
(North-West University, 2010)
Network coding is a technique used to increase the capacity of a network by combining messages sent over the network. The combined messages could be separated by using sufficient original messages which were used to combine ...
An improved error correction algorithm for multicasting over LTE networks
(2014)
Multicasting in Long-Term Evolution (LTE) environments poses several challenges if it is to be reliably implemented. Neither retransmission schemes nor Forward Error Correction (FEC), the traditional error correction ...
A topological reliability model for TCP/IP over Ethernet networks
(2014)
Network failures can originate from or be located in any one of several network layers as described by the OSI model. This investigation focuses on the role of physical topological design parameters in determining network ...
An investigation into the use of kriging for indoor Wi-Fi received signal strength estimation
(2014)
Kriging is proposed as a tool for Wi-Fi signal strength estimation for complex indoor
environments. This proposal is based on two studies suggesting that kriging might be
suitable for this application. Both of these ...
Applying genetic algorithm techniques in network intrusion detection systems
(North-West University, 2011)
The Internet has grown to an essential media for human beings that facilitate communication, information searching, banking, marketing, online education and advertising among the numerous use cases that it offers. The ...
An approach to authenticate magnetic stripe bank card transactions at point-of-sale terminals
(North-West University (South Africa) , Potchefstroom Campus, 2015)
Magnetic stripe card technology has been deployed for more than five decades worldwide and is extensively used in banking. Data embedded in them are often relied upon as a benchmark for user authentication. As such reliance ...
Design of effective decoding techniques in network coding networks
(North-West University, 2013)
Random linear network coding is widely proposed as the solution for practical network coding applications due to the robustness to random packet loss, packet delays as well as network topology and capacity changes. In order ...
Wideband spectrum sensing using sub–Nyquist sampling
(2014)
Spectrum sensing is the process of identifying the frequencies of a spectrum in which Signals Of Interest (SOI) are present. In case of continuous time signals present in a
wideband spectrum, the information rate is seen ...
