Some features of computer network modelling in the OMNeT++ environment

There are many currently available tools for computer network simulation. However, all of these are intended for use by network engineers and are not designed for research tasks. Such simulation models have insufficient flexibility and degree of parameter variability to be used for research purposes. Here, it is proposed to create a simulation model for modern computer networks which allows for the research experimentation. It is proposed to use one of the open packages available which facilitate computer network simulation modelling (for example, OMNeT++) as a base platform. Open-architecture packages allow the researcher to create specialized simulation models. With the help of models created specifically for the needs of research, it will be possible to conduct properly rigorous experiments. This paper utilizes one of the existent implementations of the Barabashi-Albert model for generating computer network topologies. This simulation model can be run and tested within the OMNeT++ discrete event simulator. (paper)
