Abstract
Among the various technologies that are constructing the pillars deep in the field of engineering, ad-hoc networks are one of the major fields of research. On the grounds of history, Mobile ad-hoc Networks (MANETs) played a prominent role in battlefield communication and other important applications, but another emerging network named as Vehicular ad-hoc Networks (VANETs) offered wireless communication led to its popular usage that resulted in the major deployment of adhoc networks. However, in VANET, secure message transmission is still a challenge, so we propose a local blockchain to disseminate the message in vehicular networks to improve the security issues. The public blockchain technique in VANET ensures trustbased secure message transmission in the Vehicular ad-hoc Network.
