- ItemPerformance prediction and analysis of a dynamic, self-configuring IoT network(Stellenbosch : Stellenbosch University, 2022-04) Hershaw, James; Wolhuter, Riaan; Niesler, Thomas; Stellenbosch University. Faculty of Engineering. Dept. of Electrical and Electronic Engineering.ENGLISH ABSTRACT: In this thesis a hypothetical wireless sensor network is modelled in software us ing discrete event simulation before a theoretical predictive model is developed for this hypothetical network using queuing theory. A study of cases in which wireless sensor networks have been implemented both practically and in simulation is conducted before a radio module is se lected with which the models can be parameterised. Various appropriate MAC layer and routing protocols are investigated and the MACAW MAC layer and AODV routing protocols are selected to be implemented in the simulated and theoretical models. The results of both the simulated model and the theoretical model are compared across a number of different possible network topologies and different transmission arrival rates. The theoretical model was able to accurately predict the behavior of the network at duty cycles appropriate for this type of network.
