As a crucial component of Internet-of-Thing (IoT), vehicular ad hoc networks (VANETs) have attracted increasing attentions from both academia and industry fields in recent years. With the extensive VANETs deployment in transportation systems of more and more countries, drivers' driving experience can be drastically improved. In this case, the real-time road information needs to be disseminated to the correlated vehicles. However, due to inherent wireless communicating characteristics of VANETs, authentication and group key management strategies are indispensable for security assurance. Furthermore, effective road message dissemination mechanism is of significance. In this paper, we address the above problems by developing a certificateless authentication and road message dissemination protocol. In our design, certificateless signature and the relevant feedback mechanism are adopted for authentication and group key distribution. Subsequently, message evaluating and ranking strategy is introduced. Security analysis shows that our protocol achieves desirable security properties. Additionally, performance analysis demonstrates that the proposed protocol is efficient compared with the state of the art.

A novel kind of ad hoc network is defeating the roads: Vehicular Ad Hoc Networks. In these networks, vehicles communicate with each other and perhaps with a roadside infrastructure to provide a long list of requests varying from transit safety to driver support and Internet access. Security is a vital concern for many Vehicular Ad-hoc Network applications. One specific serious attack, known as Sybil attack, against ad hoc networks involves an attacker illegally claiming multiple identities. In these networks, information of the real-time position of nodes is a supposition made by most protocols, algorithms, and requests. This is a very reasonable assumption, since GPS receivers can be fitted easily in vehicles, a number of which already comes with this technology. In this method, each Road Side Unit calculates and stores different parameter values (Signal Strength, distance) after receiving the inspiration packets from nearby vehicles.

“…Even though VANETs are feasible for disseminating event information, it is still a challenge to disseminate critical messages timely and reliably to a targeted area under a dynamic vehicular environment. This is due to the limited transmission range of DSRC, as well as the Contentionbased Carrier-Sense Multiple Access with Collision Avoidance (CSMA/CA) scheme in the IEEE 802.11p protocol [6]. The critical messages face delays due to MAC contention, which is not suitable for VANETs.…”

.Vehicular ad hoc networks (VANETs) have been studied intensively due to their wide variety of applications and services, such as passenger safety, enhanced traffic efficiency, and infotainment. With the evolution of technology and sudden growth in the number of smart vehicles, traditional VANETs face several technical challenges in deployment and management due to less flexibility, scalability, poor connectivity, and inadequate intelligence. Cloud computing is considered a way to satisfy these requirements in VANETs. However, next-generation VANETs will have special requirements of autonomous vehicles with high mobility, low latency, real-time applications, and connectivity, which may not be resolved by conventional cloud computing. Hence, merging of fog computing with the conventional cloud for VANETs is discussed as a potential solution for several issues in current and future VANETs. In addition, fog computing can be enhanced by integrating Software-Defined Network (SDN), which provides flexibility, programmability, and global knowledge of the network. We present two example scenarios for timely dissemination of safety messages in future VANETs based on fog and a combination of fog and SDN. We also explained the issues that need to be resolved for the deployment of three different cloud-based approaches.
