Pitfalls when using parallel streams in OMNeT++ simulations

By means of a simple OMNeT++ simulation scenario, which uses parallel streams of random numbers, we want to point out several technical pitfalls when applying different random number generators and using different initialization values for them. We describe shortcomings of the built-in random number generator (RNG) and describe traps when using modern RNGs. Quantitative and qualitative analyses of simulation results expose the danger of a careless simulation setup with regard to random components
