Abstract :
The evaluation of data-dissemination protocols in network simulation is commonly based on statistical averaging. This macroscopic approach does not take into account spatio-temporal effects that may influence protocol behavior on microscopic level. In this paper, we introduce a visualization approach based on ns-2 trace files to graphically reproduce the dissemination process step by step. Our visualizer currently supports the data-dissemination protocol EMDV and can be extended to support other protocols as well.
