Invited Talk: Location as key enabler for a Railway Collision Avoidance System based on direct vehicular ad-hoc communications

Kurzfassung

Safety of Life (SoL) services in transportation systems, e.g. for applications like collision avoidance of vehicles, requires reliable and instantaneous information exchange. In this talk we present the design of an infrastructureless ad-hoc inter-vehicle communication system that fulfills these requirements with respect to the boundary conditions in the railway environment, where a limited communication range and relatively high speed of nodes cause the network to be highly dynamic. One particular interesting aspect of the talk is how location information can contribute to increase robustness and reliability to the system design.
