Modeling, simulation, and performance evaluation of telecommunication networks

by Alice S. L. Kwok

Communication technology has been increasingly advancing during the last decade. Network resources are highly demanded by both the users and carriers. Demands on network resources place a potential burden on network performance. This th sis uses object-oriented modeling techniques to abstract the problem domain of a network for analysis. Commercial tools, namely COMNET III and OPNET, were used to build and to simulate the network models. The tools themselves are validated using a Poisson Process. Analytical results are used to help validate the simulations. The thesis also provides a brief description of the telecommunication standards that the models represent, allowing readers a better understanding of the network structure and behaviour.
