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 on the physical implementation
thereof. One exception is COPE where network coding is implemented in wireless
networks for unicast transmission sessions.
In this dissertation, we discuss the physical arrangement of wireless nodes to form
topologies suitable for the implementation of network coding. We implement linear
network coding in wireless ad hoc networks for multicast transmission sessions.
We calculate the areas in which each wireless node must be located for a specific network
coding suitable topology to be formed. The identified topologies are simulated
in OPNET Modeler and then implemented on a six node testbed, to analyse the effect
of implementing network coding in these topologies.
We provide results indicating the trade-off between reduced network load and higher
end-to-end delay when our developed network coding algorithm is active in the respective
topologies. The results indicate that the developed network coding scheme
will produce better overall performance when implemented in sensor networks or
highly congested ad hoc networks. / Thesis (M.Ing. (Computer and Electronical Engineering))--North-West University, Potchefstroom Campus, 2011.
