Vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications are gaining increasing importance in vehicular applications. This project will study state-of-the-art service/protocol for V2V and V2I communications and focus on evaluating the reliability and performance of data communication over the wireless channels using Dedicated Short-Range Communication (DSRC). DSRC is a fundamental short to medium range communication channels and a set of protocols and standards that are designed specifically for V2V and V2I communications. IEEE 802.11p is a protocol that has been standardized as the medium access control (MAC) layer of the DSRC standard. Parameters of DSRC service and the IEEE 802.11p protocol can significantly affect the reliability and performances of the V2V and V2I communications. Thus, system designers need systematic methods and tools for performance evaluation and system optimization through parameter tuning for practical vehicular applications. This project will study DSRC communication link-level performance and reliability metrics, including packet delay and packet delivery ratio (PDR). It will also study application-level metrics, including T-window reliability and Time-to Successful Reception (TSR). We plan to investigate the tuning of DSRC protocol parameters by studying their effects on the above reliability and temporal performance metrics, through integrated theoretical modeling, simulation study, and testbed validation. The joint research team at McGill University and General Motors has track records of successful research in areas closed related to this project including wireless communications and networking, and vehicular applications. The team also has successful history and fruitful results in academia-industry collaborations. These necessary expertise and experiences lay a solid foundation to the success of this project on performance and reliability study of DSRC supported applications, which will form a key technology enabler for next generation vehicular systems.
