Cognitive radio adhoc vehicular network (CRAVENET): Architecture, applications, security requirements and challenges

Abstract

This paper proposes and discusses the topic of cognitive radio ad-hoc vehicular networks (CRAVENET) and their architecture along with applications, security requirements and challenges that arise in architecting such networks. With the ever grower demand for spectrum, there exists an urgent need to improve spectrum utilization in wireless networks. Cognitive radio technology, which serves as a means to improve spectrum utilization, is expected to become an important part of diverse fields including the field of vehicular ad-hoc networking. The CRAVENET paradigm introduces entirely new challenges and security threats. This paper proposes an architecture with reliable authentication scheme to enhance security in CRAVENET.
