Design Secure and Application-oriented Vanet

Vehicular ad hoc network (VANET) is recognized as an important component of Intelligent Transportation Systems. The main benefit of VANET communication is seen in active safety systems, which target to increase safety of passengers by exchanging warning messages between vehicles. Other applications and private services are also permitted in order to lower the cost and to encourage VANET deployment adoption. To successfully deploy VANET, security is one of the major challenges that must be addressed. Another crucial issue is how to support different applications and services in VANET. In this paper we propose a secure and application-oriented network design framework for VANET. We consider both security requirements of the communications and the requirements of potential VANET applications and services. The proposed framework consists of two basic components: an application-aware control framework and a unified routing scheme. Besides the network design framework, we further study a number of key enabling technologies that are important to a practical VANET. Our study can provide a guideline for the design of a more secure and practical VANET.
