The automatic German toll system is both a software-intensive system – relying on the on-board units to collect the toll charges due – and a socio-technical system – the user can influence the system behaviour. The overall dynamic system behaviour emerges both from the technical implementation of the system and the users’ interaction with the system limiting the effectiveness of common software engineering...
Using an existing large-scale realistic discrete event simulation model of a mobile distributed system we model the infrastructure and dependencies of 2G, 3G and 4G mobile data networks. We investigate the effects of the different network generations and of transitioning connections between networks on the typical behaviour of the distributed system. In particular we enable the model to simulate regional...
We are using a detailed realistic discrete event simulation model of the automatic German toll system to study resource usage of the mobile data network for various system configurations. Starting with an existing simulation model [1] we describe the driving patterns used in the simulation and the functionality added to the simulation model. Next we explain enhancements in simulation performance implemented...
