  • Abstract:
    The main objective of this project is to develop a secure, reliable, high throughput and integrated wireless network for Vehicle-To-Vehicle (V2V), Vehicle-To-Infrastructure (V2I) and intra-vehicle communications. Novel techniques and communication protocols were developed to ensure that safety messages are transmitted reliably, securely and efficiently.

    The secure network protocols using IEEE 802.11i authentication and anti-jamming dynamic channel hopping protocol were implemented and the results show an improved performance. These security mechanisms will avoid not only attackers from disrupting critical vehicle communication but also enable high connectivity and performance even in the presence of benign transmissions that may interference with the vehicle network transmissions. The adaptive multi-hop routing ensures end-to-end connectivity by considering the connectivity of each wireless links. These protocols demonstrated how to transmit high priority urgent messages reliably. The rate adaptation algorithm was implemented and the results show improved performance since it avoids packet collisions and tolerate channel fading in the harsh vehicle environment. The precise vehicle positioning technique is integrated with the wireless vehicle networks that provide reliable, secure and high throughput transmissions of GPS messages.

    The results of our studies on the integrated wireless vehicle networks for V2V, V2I and intra-vehicle networks show that the integrated network can satisfy the security, reliability and throughput performance requirements of Electronic Stability Control (ESC) systems and other connected vehicle safety applications. The demonstration of the intra-vehicle wireless networks on the commercial tractor trailers at the National Center for Asphalt Technology (NCAT) test track for supporting ESC systems showed that this is feasible in real-world vehicle networks under normal operating conditions.
