On the effectiveness of W2RP in physical environments
Future V2X applications rely on the exchange of large sensor data samples and are subject to stringent safety and timing constraints. Due to the lossy nature of the wireless radio channel, data exchange of such larger samples has to be protected by a real-time capable reliability mechanism in order to recover from critical data loss in time. However, state-of-the-art V2X technologies so far are primarily designed for exchanging single packet data, which ignores the challenges of reliable transfer of larger data objects. The recently proposed DDSbased W2RP protocol, addresses such issues. Its effectiveness has been extensively tested and proven in an OMNeT++ simulation environment. In this work we developed a proof-of-concept implementation based on the open-source DDS implementation Fast DDS that can be used to validate the W2RP simulative results in a real-world environment. First experiments showed that the reliable exchange of large samples is possible by using W2RP.
