Optimizing-strategies for a time-efficient evaluation of position-specific communication aspects in disaster relief scenarios

Satellite systems may integrate Standardized Digital Professional Mobile Radio systems into an existing infrastructure over long distances without the need of dedicated transport networks, even in disaster relief situations. Simulation-based decision support can predict possible interferences like shadowing or multipath effects, but especially in time-critical emergency scenarios, a trade-off between minimizing the simulation time and maximizing the accuracy of the modeled scenario needs to be determined. Both factors have significant influence on the degree of accuracy in the results. Therefore, this paper presents a pre-simulation routine called Optimization Matrix, which reduces the simulation time to a certain value (e.g. journey time of the rescue forces) but keeping the resulting simulation error acceptable for the given case of application. In addition, the Optimization Matrix was integrated into a framework to enable an evaluation of a selected area-of-interest and a result visualization in an interactive 3D map view.
