Enhancement of Communication Model for Driving Simulators by Relevant Physical Effects of Radio ropagation.

Kurzfassung

Vehicle-2-Vehicle (V2V) and Vehicle-2-Infrastructure (V2I) communication has been an emerging area of interest in the recent times. It offers applications ranging from road safety (e.g.: collision avoidance) to infotainment (e.g.: multimedia, navigation, traffic information etc.). Due to growing number of driver assistance systems, it is very important to evaluate the interaction with users and acceptance of these systems. Suitable tools for doing this are driving simulators. The goal of this master thesis is to enhance an already existing communication model for V2V communication scenarios that is used for the driving simulators of the DLR-Institute of Transportation Systems. The current communication simulation implements a simple propagation model based on free space communication and is already integrated in the simulator environment that provides all necessary information and parameters. This work focuses on the enhancement of existing communication model with two major physical effects: the multi-path propagation to provide "urban canyon" effects and the directional antenna (main lobe) to take the direction of the communication into account. Algorithms for assessing the environment are developed based on the open source graphics engine "OpenSceneGraph" and the prototype implementation is later integrated in the DLR Institute’s own system architecture called "Dominion".
