A Novel Approach for Realistic Emulation of Vehicle-2-X Communication Applications

New applications in future intelligent transportation systems are to enhance both safety and traffic efficiency. Wireless vehicular communication is to provide the basis for the new Vehicle-2-X communication applications. However, field tests are necessary to make them usable and validate the improvements that are to be achieved. Since the realization of the field tests is rather complex and expensive, detailed simulations are essential to prepare the tests in the real world and reduce their costs. Currently, software simulators do not support all aspects necessary for a proper validation of Vehicle-2-X applications. In this paper, an integrated software simulation environment that fulfils the special requirements of Vehicle-2-X applications is presented. Furthermore, our testbed architecture that allows simulating Vehicle-2-X communication under real physical conditions is introduced.
