Graphical processing of data derived from network simulation Comparative analysis of tools as a complement to the NS-2 simulator

Data processing obtained from the study of a phenomenon is one of the fundamental activities in any research. In the network simulation, in particular, the format of visual representation, through graphic tools, offers a better interpretation of the simulated scenario and allows a clearer understanding of the parameters analyzed. Choosing the right tools to perform this task, as well as the development of the necessary skills to handle them, are essential in the study and teaching of concepts related to computer networking. This paper presents in a comparative way some tools that are used in the NS-2 simulator graphic representation results. There's also an explanation of advantages and disadvantages, scope, limitations and requirements for the use of each one of them.
