Hoc Networks

Over the past few years, there has been significant research interest in field of vehicular ad hoc networks (VANETs). Wireless communication over VANETs supports vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I) communication. Such innovation in wireless communication has improved our daily lives through road safety, comfort driving, traffic efficiency. As special version of MANETs, VANETs bring several new challenges including routing and security challenges in data communication due to characteristics of high mobility, dynamic topology. Therefore, academia and the auto mobile industry are taking interest in several ongoing research projects to establish VANETs. The work presented here focuses on communication in VANETs with their routing and security challenges along with major application of VANETs in several areas.

Hoc Networks

Vehicular Ad-hoc NETworks (VANETs) currently provide a prominent field of research, which aims at improving everyday road safety and comfort. To achieve this, the deployment of several potential applications is envisioned, promising to provide extraordinary benefits, but will also represent important security challenges due to the unique characteristics of VANETs. In this chapter, VANET’s security issues are addressed, and the most outstanding security approaches are discussed. As a proof of concept, a PKI -based protocol, able to cope with the interoperability issues among untrusted CA domains is presented, and the trade-offs between security and performance are empirically analyzed and stressed.

Continuous Progression

Recently, vehicular ad hoc networks (VANETs) got much popularity and are now being considered as integral parts of the automobile industry. As a subclass of MANETs, the VANETs are being used in the intelligent transport system (ITS) to support passengers, vehicles, and facilities like road protection, including misadventure warnings and driver succor, along with other infotainment services. The advantages and comforts of VANETs are obvious; however, with the continuous progression in autonomous automobile technologies, VANETs are facing numerous security challenges including DoS, Sybil, impersonation, replay, and related attacks. This paper discusses the characteristics and security issues including attacks and threats at different protocol layers of the VANETs architecture. Moreover, the paper also surveys different countermeasures.
