Security and cooperation in vehicular delay tolerant network and its applications

Road safety and efficiency are major concerns worldwide. Therefore, it is crucial to explore new techniques to improve road safety and efficiency. The proposed research program aims to investigate the applicability of emerging vehicular communication networks, also known as vehicular ad-hoc networks (VANETs), as a promising approach to increasing road safety and efficiency. In VANETs, vehicles are equipped with wireless communication, positioning and computation devices with a variety of vehicle applications enabled by communication between vehicles such as emergency braking warning. Unfortunately, VANETs have faced various security threats and privacy concerns which would jeopardize public safety and become the main barrier to the acceptance of such a new technology. As a result, security is crucial to success of VANETs, and so is thereby a prerequisite for market-ready VANETs. In the past, insufficient attention has been paid to this area of research, in particular security in vehicular delay tolerant networks (DTNs), where end-to-end network connectivity between vehicles is not available. Traditional approaches may not be suitable in such a vehicular DTN due to its unique characteristics, such as intermittent connectivity due to high-speed mobility of the network node (or vehicle), resource scarcity, and the extremely large amount of network nodes. The proposed research is envisioned to solve the security and privacy issues in vehicular DTNs, which have not been taken into consideration in previously reported studies. It is expected that this research program will contribute to the discovering of new ideas and the development of innovative automotive products and services. As a result, new business models and revenue streams can be devised to foster growth and promote the troubled automobile industry in Canada. The research will also lead to HQP training in information security and vehicular communication techniques, which will greatly contribute to the Canadian communication, automobile and information security industries.
