A comparison of wireless node topologies for network coding using practical path-loss models
Böning, F.J.; Helberg, A.S.J.; Grobler, M.J. (IEEE, 2010)In this paper, we discuss the physical arrangement of wireless nodes to form topologies suitable for the implementation of Network Coding. Boundaries for the most favorable placement of the nodes to form Bow-Tie and Butterfly ... -
Error correction with the implicit encoding capability of random network coding
Von Solms, Suné; Grobler, Magdalena J.; Helberg, Albert S.J. (Springer, 2010)In this paper, we present a technique for a network error correcting code using Random Network Coding. We introduce a novel error correction scheme that uses the implicit encoding capability of Random Network Coding. This ... -
An evaluation of configuration parameters affecting network coding on the data link layer in a wireless network
Van Wyk, J.L.; Helberg, A.S.J.; Grobler, M.J. (IEEE, 2011)Network Coding, introduced in [2], promises significant theoretical capacity gains in multicast networks. Practical implementations in underlay networks are however quite complex in practice and performance is subject to ... -
The intuitive approach to engineering design of a multi-cultural group of engineering students
Grobler, M.J.; Helberg, Albert S.J. (IEEE, 2011)We all acknowledge the importance of design in the world of an engineer, and much effort goes into teaching the best practices to our students. We however seldom examine what their intuitive approach to engineering design ... -
Optimal passive optical network planning under demand uncertainty
Van Loggerenberg, S.P.; Ferreira, M.; Grobler, M.J.; Terblanche, S.E. (SATNAC, 2014)As a result of ever-increasing demand for access level bandwidth, long deployment cycles and the popularisation of more economically viable Point-to-Multipoint (P2MP) networks, service providers are moving to extensively ... -
Received power prediction of a terrestrial TV broadcasting transmitter using ordinary kriging interpolation
Boshoff, Willem H.; Grobler, Magdalena J.; Ferreira, Melvin (SATNAC, 2014)Radio Environment Mapping (REM) provides information useful for many different applications in the telecommunications field. In this paper, the authors evaluate the ability of ordinary kriging (OK) to produce a REM ... -
Warm-start heuristics for solving the passive optical network planning problem
Luies, Ruan; Terblanche, Stephanus; Grobler, Magdalena (Univ Stellenbosch, 2018)The use of automated network planning systems is crucial for reducing the deployment cost and planning time of passive optical telecommunication networks. Mixed integer linear programming is well suited for the purpose of ...
